Importance of Using Tested Accessories for AB Cable Power Distribution Lines

Aerial Bundled Cable (ABC) is an innovative concept for Over Head (OH) power distribution. When compared to the conventional bare conductor OH distribution system, ABC provides higher safety and reliability, lower power losses, stability in voltage regulation and ultimate system economy by reducing installation, maintenance, and operation cost.

The construction and mechanical properties of the AB Cable system originate from the HD 626 standard. The AB Cable itself is available in several constructions including the Insulated Messenger system, the Self-Supporting System (2 core or 4 core), and the uninsulated messenger system. The commonality amongst all these systems is that the current-carrying high strength aluminum alloy phase conductors are insulated with PE or XLPE material and then twisted around the messenger cable (insulated messenger and uninsulated messenger systems) or twisted amongst themselves (self-supporting system). You can read more about the cable construction of AB Cables in our article here: Components of an LV AB Cable Distribution Line

As mentioned in our article on the ‘Lifespan of ABC Lines in Moist / Wet Environments’, the most influential factor in aging ABC cables is the use of non-standard cable connectors, accessories and clamps because they allow water ingress which slowly damages the cable.

Thus, as with any power distribution system, if the goal is to minimise downtime of the line and extend its lifetime, then the accessories that are used along with a LV AB Cable system should be tested according to the relevant testing standards. The following article goes into detail on the testing standards and their requirements for the various accessories and components used along with a LV AB Cable Power Distribution system.

Testing of AB Cable Accessories

The testing of Accessories to Low Voltage AB Cable systems can be broken down into 3 major testing buckets:

Mechanical Testing

Electrical Testing

Environmental Testing

The major products that are used as accessories to Low Voltage AB Cable systems are as follows:

Suspension Clamps:

Suspension Clamps are used along with a bracket or other supporting hardware to suspend and grip, without damaging, a LV AB Cable system. As shown in the images below, they can also be used in conjunction with insulation piercing connectors to provide service connections by tapping the mainline.

Anchoring Clamps:

Anchoring Clamps are used along with a bracket or other supporting hardware to strain the messenger or cable to terminate the line or to provide an angle of up to 90 degrees for the LV AB Cable system without damaging the cable’s insulation.

Service Clamps

Service Clamps are used along with a bracket or other supporting hardware to strain the insulated service conductor of a LV AB Cable system to provide turn angles, anchor service lines on walls, or support tap-offs for the service lines without damaging the cable’s insulation.

Insulation Piercing Connectors (IPC’s)

Insulation Piercing Connectors are used on all AB cable systems (messenger wire & supporting system) to take a tap connection. This tap can be used to continue the line, distribute the line, used in street lighting or in-service connections to households. The design allows the connection to be completely sealed against any water ingress, thus acting as a waterproof connector

Midspan Joints or Insulated Bimetallic Lugs

Pre-insulated midspan joints are used for the insulated AB cables phase or neutral to join two cables.

Pre-insulated Bimetallic lugs are used for insulated AB cables phase or neutral to terminate the cables.

Low Voltage Distribution Boxes

A distribution box is a key component of an electrical supply system. From a single, common enclosure, it helps to divide an electrical power main feed into multiple subsidiary outgoing connections that can be used to provide electrical connections to individual homes, buildings, or other requirements.

Mechanical Testing

The clamps and connectors mentioned above undergo load tests, slip tests & endurance tests to ensure that the device can withstand the load conditions of the AB Cable in real-world scenarios without slippage. The midspan joints and pre-insulated bimetallic lugs are put through their mechanical tests after the crimping of the products.

The insulation piercing connectors also have to make their connection without causing damage to the conductor. Thus, the tap and main conductor are put through a tensile strength test after the application of the IPC to ensure that cable strands have not been cut through the application of the product which would weaken the conductor.

Electrical Testing

The clamps and connectors are put through a 6 kV test to ensure that none of the components of the product become electrified during the test. The reason for this test is to ensure the safety of the power line worker or any other person who may accidentally touch the product while the line is live.

As mentioned earlier in the article, the most influential factor in aging ABC cables is the use of non-standard cable connectors, accessories, and clamps because they allow water ingress which slowly damages the cable. Since the primary function of the Insulation Piercing Connector is to pierce through the XLPE insulation covering the aluminium conductor to form an electrical connection, water ingress on an AB Cable is most likely at the location of the IPC if non-standard products are used. Axis IPC’s are tested to a 6kV underwater test to ensure a waterproof connection without any electrical leakage.

Environmental Testing

Since these products are used on outdoor overhead power distribution systems, the clamps must undergo corrosion & climatic aging to ensure that the clamps can withstand the harsh conditions that exist outdoors such as direct sunlight, rain, etc.

Distribution Boxes

Low voltage distribution boxes for AB Cable Systems are a complex product that requires testing as per many different standards including IS 14772, IS 8623, UL 746C & IEC:60695-2.

Mechanical Testing

The distribution boxes are put through several mechanical testing including impact tests, IP tests, glow wire tests and flammability tests. The purpose of the impact tests is to ensure that the product is not brittle and can endure some physical damage in the outdoor environment. IP testing ensures safety from water and dust ingress. The glow wire and flammability test are both conducted to make sure that, in case of a fire, the box is able to self-extinguish a fire and not propagate the fire.

Electrical Testing

Axis Low Voltage Distribution Boxes are also put through electrical tests where they are tested for surges from 2 kV to 4 kV. The purpose of the test is to ensure that there is no leakage current and therefore no chance of a human suffering an electrical shock in case they touch the product. This test also showcases that the box would be intact without any failure in case of an electrical surge.

Environmental Testing

As with all the other products in the system, these distribution boxes are used outdoors and are thus tested to check for the effect of UV rays on the product.

Conclusion

At Axis, we conduct an intensive system of testing for all our products as per the appropriate international testing standards during design, validation, and final production. We are confident of our products and offer them to our customers with the assurance that our products will not fail on the line. It is paramount that contractors use tested products along with their AB Cable systems. To learn more about Axis’s range of tested AB Cable Accessories, please read our catalogue here or contact us through this form.

Along with using the correct products, it is also important that the products are installed correctly. To watch how to correctly install our range of AB Cable Accessories, please watch our series of videos here.

Electric vehicle high-voltage wiring harness structure design and its function?

New energy vehicle high-voltage wiring harness is mainly composed of connectors, terminals, cables, coverings and other parts.

Introduction of high-voltage connector standards. At present, connector manufacturers basically refer to the four major European OEMs: Audi, BMW, Daimler, and Porsche jointly developed the industry standard LV series standards; in North America, they mainly implement the relevant standards of SAEuscar, in order to better adapt to More and more HEV requirements, the SAE-USCAR 2 standard was updated in 2008, and the voltage level was raised from the original 20V to 600V. China also has its own high-voltage connector standard: GB standard. In terms of content and standards, there are still many areas that need to be improved.

Introduction to the structure of high-voltage connectors. It is mainly composed of four parts: contacts, insulators, shells and accessories. Among them, the contacts are the core components of the connector to complete the optical and electrical signal connection. The optical and electrical signals required by the vehicle during driving are completed by the insertion of the contacts. The insulator and the shell mainly play the role of fixing, insulating and mechanical protection; the accessories are divided into structural accessories and installation accessories, such as clamps, cable clamps, sealing rings, gaskets, etc. Mounting accessories such as screws, nuts, spring rings, etc.

Introduction of high-voltage wire harness crimp terminals. The metal conductor inside the terminal is the core part of the terminal, which transmits the voltage, current or signal from the external wire and cable to the corresponding contact of the corresponding connector. Therefore, the contacts must have excellent structure, stable and reliable contact retention force and good electrical conductivity; the function of the insulator is to keep the contacts in the correct position, and to make the contacts between the contacts and the shell. Insulators are insulated from each other, so the insulating parts must have excellent electrical properties, mechanical properties and process forming properties; the insulator not only acts as insulation, but also provides accurate alignment and protection for the protruding contacts. A feature that is tightly secured to the device. The terminals need to be well fixed to ensure the normal operation of the power transmission and signal control of the control system.

Introduction of high-voltage cables for new energy vehicles. The high-voltage cable material is affected by the environment and function. The temperature near the generator and power battery is high, and there are many corrosive liquids and gases. The cable needs to have high temperature resistance, acid and alkali resistance, corrosion resistance and other properties; the wire on the automatic transmission It needs to have oil resistance, high temperature resistance and other properties; weak signal sensors need to use shielded wires… Automobile wiring harnesses usually use stranded copper wires, and the products need to be flexible, small bending radius, high temperature resistance, acid and alkali resistance, oil resistance, wear resistance, Halogen-free flame retardant and other characteristics, Paige Rui is a manufacturer of energy storage wiring harnesses and new energy electric vehicle wiring harnesses.

Introduction of high voltage wiring harness cover. The covering is mainly divided into corrugated tube and heat shrinkable tube. The temperature resistance level is -40°C-125°C. It needs to meet good elasticity and flexibility, and play a role in insulating and protecting the cable.

The Features and Components of Low Voltage Switchgear!

Due to the success of new researches various new and latest technologies have been introduced in the market. In the electrical world, the Low Voltage Switchgear and Portable Generators are the latest technology to which everyone wants to install in their homes and offices for various reasons.

A wide variety of LV power distribution equipment is available on the market to meet the different needs of the specific residential building, commercial and industrial facilities. High-quality manufacturers are specialized to develop the increasing array of LV power distribution equipment options, and also they have enough knowledge and skills to understand the specific needs of end-users in order to provide tailored guidance on how best to meet their specific needs.

What is Low Voltage Switchgear?

Low voltage switchgear is used to control, monitor, and protect low-voltage distribution systems. It is an intelligent combination of electrical power distribution with automation system and energy management system which increases the energy efficiency of residential buildings and commercial or industrial plants. Moreover, the maintenance and operational processes can be continuously improved by using intelligent switchboards, communication, and capable components.

Low voltage switchgear or LV distributes power throughout a facility while simultaneously protecting a system's electrical equipment. Low-voltage breakers allocate power and sense faults within a system. A quality new or rebuilt low-voltage circuit breaker can either function separately or as part of a larger unit to clear faults and maintain power within a facility.

Most of the people don’t have proper knowledge of LV switchgear and hesitant to buy circuit breaker equipment or rebuilt switchgear. If you want to know more about LV switchgear in details then stay with us to the end of this article:

LV switchgear is useful and beneficial equipment where the production of power frequently fluctuates. It provides centralized control of low voltage power circuits and other equipment for industrial, commercial and utility installations including transformers, power feeder circuits Portable Generators, and motors.

While on the other hand, the low voltage distribution equipment is required to protect the area where whole the systems have been installed as it monitors critical power electrical distribution safely and efficiently. The LV switchgear provides an optimum solution in such situations.

Unlike the other alternatives reviewed, switchgear uniquely endures short-circuit currents for 30 electrical cycles. It allows the downstream protective device nearby to the fault to open and resolve it.

This potential of the device referred to as short time ratings. Molded case circuit breakers in Low Voltage switchboard assemblies do not provide these ratings. The components of Low-voltage switchgear are circuit breaker compartments, structures, secondary control compartments, low voltage drawout power circuit breakers, primary and secondary power connections, and busbars and customer termination areas.

Low voltage drawout power circuit breakers protects the electrical circuit from damage due to the short circuit or overloading power. The term drawout states to the ability to connect to the primary and secondary power connections without using connector kits, bolts, nuts, or other mechanical means.

Components of an LV AB Cables Distribution Line

Low Voltage Aerial Bundled Cables, which have an insulating layer of XLPE, are an innovative concept for the distribution of electricity to households, street lights or other low voltage applications. These electrical distribution systems are practical not only in congested cities where the insulation provides safety and manoeuvrability but are also useful in rural areas where live line maintenance is much easier than using bare conductors. You can read more about this in our article on the “Advantages of Low Voltage Aerial Bundled Cables for Overhead Power Distribution”.

According to research published in 2017, “XLPE cables are expected to last or service well beyond the 40-year design life under normal circumstances”. However, this long lifespan can be severely reduced if improper clamps and connectors are used along with the AB Cable. According to the research, the most influential factor in ageing ABC cables is the use of non-standard cable connectors, accessories and clamps because they allow water ingress which slowly damages the cable.

The appropriate components to be used along with the AB Cable system are listed below.

1. Aerial Bundled Cable (ABC)

a. Insulated Messenger System: An insulated messenger system (also called the French system) consists of 3 black, weather-resistant XLPE or PE insulated phase conductors twisted along with an insulated messenger conductor made of a high strength Aluminum alloy which serves as a dual purpose earthing and/or neutral messenger wire.

b. Self-Supporting System (Two Core or Four Core System): The self-supporting cable system consists of 2 or 4 PE or XLPE black, weather-resistant insulated conductors. The mechanical strength of all the cables is equal such that, when strained, all the cables will equally bear the load of the system.

c. Uninsulated Messenger System: An uninsulated messenger system (also called the Finnish system) consists of 1-4 black, weather-resistant PE insulated phase conductors twisted around a messenger conductor made of a high strength Aluminum alloy.

2. Poles

a. Wooden Poles

b. Cement (RCC – Reinforced Cement Concrete, PCC – Plain Cement Concrete Poles)

c. Steel Tubular Pole (Stepped pole, Swaged pole).

d. Rail Pole.

3. Suspension System:

a. Suspension Clamps for LV AB Cables are used along with a bracket or other supporting hardware to suspend and grip, without damaging, the insulated or uninsulated messenger or the self-supporting system of a LV ABC system by means of an adjustable lock that accommodates a range of cable sizes.

4. Anchoring System:

a. Anchoring Clamps for LV AB Cables are used along with a bracket or other supporting hardware and are used to strain the insulated or uninsulated neutral messenger or the self-supported system to terminate into transformer leads or mains for industrial/residential supply. They are also used to provide angles to a LV ABC system without damaging the cable’s insulation.

5. Taking service lines or tap connections:

a. Service Clamps are used along with a bracket or other supporting hardware and is used to strain the insulated service conductor of an LV-ABC system without damaging the cable’s insulation. The main application of Service Clamps is to bring service connections to households or street lights.

b. Insulation Piercing Connectors are used on all AB cable systems (messenger wire as well as self-supporting system) to take tap connections. This tap can be used to continue the line, distribute the line, be used in street lighting or in-service connections to households.

6. Service line distribution

a. Distribution Boxes are used to take multiple connections from a single enclosure. These connections can be used for distribution to households.

7. Other Hardware

a. Midspan Joints are used for insulated ABC cables on stranded phase and neutral to join two cables.

b. Insulated BM Lugs are used for insulated ABC cables on stranded phase and neutral to terminate the cables.

c. Elastomeric or Heat Shrinkable End Caps are used to safely terminate the ends of the AB Cable. Elastomeric End Caps are usually supplied with insulation piercing connectors.

d. Fixing Nails are used to support Aerial bundled cable on façades.

e. Stainless Steel straps are used along with the Fixing Nails to accommodate an additional bundle if required. Stainless Steel Cable ties are also used to fix brackets and distribution boxes onto the electric pole.

f. Tensioner is used to tension the steel straps which are mounted on the poles to hold the brackets or distribution boxes in place.
