A lightweight structural electrical support device called a cable tray protects against overheating and fire buildup issues while permitting the safe harnessing and transportation of lines and electrical flexible conduits across open spans.
Insulated electrical cables used for power distribution, control, and communication are supported by a cable tray system. In marketable and industrial construction, cable trays are constantly used for cable operation as an alternative to open wiring or electrical conduit systems.
Since new cables can be installed by placing them in the tray rather than pulling them through a pipe,
they're especially helpful in instances when changes to a wiring system are planned.
Types of cable trays
Ladder cable tray
It has rungs connecting its two side rails.
This kind of cable tray works well because you can fluently reach the cables from either the top or bottom thanks to
the ladder rungs. When the locations of the cables in horizontal cable charger runs must be maintained or
in horizontal cable tray runs, the rungs of the ladder cable trays serve as ideal anchors for tying down the cables.
The perforated type comprises side rails and a bottom vent. Compared to the ladder type, it provides cables with further support.
Solid bottom cable tray
Solid-bottom (non-ventilated) cable trays are preferred for
fiber-optic cable installations when the performance of the system may be impacted by cable drooping. still,
a concern for electromagnetic/radio-frequency interference protection is the fundamental
justification for choosing solid-bottom trays.
Wire mesh cable tray
Stainless steel wires are welded together to produce a
mesh that resembles a basket to produce a type of cable tray that's also known as a basket cable tray.
Cable Trays are mainly used for low voltage, telecommunication, and fiber optic cables supported on short spans.
a metal tray that can be utilized for extremely tiny cable installations is all that it is
What type of cable tray to choose and why?
There are three different types of cable trays ladder, ventilated trough,
and solid bottom. What factors led you to choose a certain style of cable tray?
The kind of cable tray that has the attributes that best meet the requirements of the project
should be chosen by the engineer or developer.
Ladder cable tray
About 75 of the cable tray wiring system installs employ ladder cable trays. Due to its numerous appealing qualities, it's the most common form of cable tray.
The most amount of air can freely travel through the cables in a ladder cable tray without covers. This enables the cable's conductors to effectively disperse the heat they produce. Under these circumstances, a correctly built cable tray wiring system's conductor insulation will not heat up over its maximum operating temperature. The cables will not deteriorate too soon from high operating temperatures.
The ladder cable tray's most typical rung distance is 9 elevation. All sizes of cables can be supported by this gap. Since the support distance prevents any discernible sagging of the small cables between rungs, this spacing is ideal for the small diameter Type PLTC and TC lines. Although the 12 18-inch rung spacing provides enough string support, some installations may find the tiny amount of small-diameter string sagging between rungs to be uncomely.
Ventilated trough cable tray
Aesthetics are the only consideration when choosing between a ventilated trough cable tray and a ladder-type cable tray. There's no evidence of minor cables sagging. There's some additional support for the cables in the ventilated trough cable tray over the ladder cable tray, but it isn't much. It doesn't affect the cables' service history or lifetime.
Solid bottom cable tray
Concern regarding EMI/ RFI shielding protection for extremely sensitive
circuits is the primary driver for choosing a solid bottom cable tray( with covers). However, a solid bottom steel cable
tray with steel covers offers a good amount of shielding, If the installation is complete with no breaks or holes. According
to some engineers and contrivers, all electrical circuits must be completely contained by metal, hence they specify solid bottom
cable trays (sometimes with coverings). Just supporting cables that are intended for such setups are contained in the cable trays. Rarely do cables in a cable tray run to fail.
There are no cable failures brought on by poor cable support in cable trays.
