Know All About Cable Trays
Cable trays are the best alternatives to wire ways and electrical conduits. The sole objective of cable trays is to enclose and safeguard the cables.
Cable trays are efficient in safeguarding different types of wires like
· High-voltage power lines
· Power distribution cables
· Control cables
· Telecommunication cables
· Fiber optical cables
Cable Tray’s Objectives:
Cable trays are the crucial components of protective power and communication wires and cables.
Not only do cable trays support and protect power and signal cables, but they also assist in upgrading, expanding, reconfiguring and relocating the networks.
The majority of cable tray systems are open and supports efficient heat distribution and convenient access for repair or replacements.
Most of the cable trays are typically suspended from celling or affixed to walls, but there are cable trays that can be used for underfloor use.
Major types of cable trays:
The popular types of cable trays are-
· Perforated type
· Solid-bottom type
· Wire mesh
An engineer or construction professional determines the type of cable trays required for the project. The cable trays type selection depends on the situation and environment.
The cable tray selection also depends on the total number of the cables, size, spacing and overall weight of the cables.
Now here we are going to talk about different types of cable trays-
Ladder cable tray:
This type of cable tray comes with two side rails connected by rungs. This particular type of cable tray is highly effective as it provides easy accessibility to the cables, both from top and bottom.
The rungs provide perfect anchors for tying down the cables in the non-horizontal cable tray runs or one place the cables in the horizontal cable tray runs.
Perforated Cable Trays:
It comes with a ventilated bottom with side-rails. Perforated cable trays ensure more support than the ladder-type of cable trays.
Solid-bottom cable trays:
When it comes to installing fiber-optic cables where drooping of cable may affect the system performance, solid-bottom cable trays can be the right choice.
Choosing solid-bottom cable trays is a great decision for protecting electromagnetic/radio-frequency interference protection.
Wire-mesh cable trays:
Wire-mesh cable trays are also known as a basket-cable trays. This kind of cable trays is made of stainless steel wires that are connected with wielding. It forms a basket-like mesh.
Channel Cable Tray:
It’s a metal cable tray and this kind of cable trays are primarily used for small cable installation.
Different Types of Cable Tray Materials:
Aluminum: Aluminum is popular for its corrosion-efficient ability and high strength-to-weight ratio. Another advantage of using aluminum is its lightweight nature.
Steel: it allows electric shielding and comes with low thermal expansion.
Stainless steel: This material is popular for its super corrosion resistance and it can easily withstand high temperature.
Fiberglass: This is the only non-metallic material used in cable trays. It is non-conductive and corrosion-resisting. Fiberglass is used for its lightweight nature.
The cable trays should be cleaned on a regular wise otherwise, it may accumulate dust particles and clutters.
