In the electrical wiring of buildings, a cable tray system is used to support insulated electrical cables used
for power distribution, control, and communication. Cable trays are used as an alternative to open wiring or electrical conduit systems,
and are commonly used for cable management in commercial and industrial construction. They are especially useful in situations where changes
to a wiring system are anticipated, since new cables can be installed by laying them in the tray, instead of pulling them through a pipe.
A cable tray is a unit or assembly of units or sections and associated fittings forming a rigid structural system used to securely fasten or support cables and raceways.
Several types of tray are used in different applications. A
Common cable trays are made of galvanized steel, stainless steel, aluminium, or glass-fibre reinforced plastic . The material for a given application is chosen based on where it will be used. Galvanized tray may be made of pre-galvanized steel sheet fabricated into tray, or may be hot-dip galvanized after fabrication. When galvanized tray is cut to length in the field, usually the cut surface will be painted with a zinc-rich compound to protect the metal from corrosion.
The last point is about the flexibility of the cable tray manufacturer you have set for the company. Are they willing to customize the product or service model to meet your requirements? Flexibility is important to ensure that you get the product you are looking for rather than the general product.
A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough.
Trough Tray is a cable tray consisting of ventilated or solid bottom contained within longitudinal side members. Our solid bottom trough tray is used to carry smaller instrumentation, data communications, computer, telephone, control and fiber optic cable from one location to another.
A deep, solid enclosure for cables is called a cable channel or cable trough. ... Channel Tray provides an economical support for cable drops and branch cable runs from the backbone cable tray system. Channel cable tray is used for installations with limited numbers of tray cable when conduit is undesirable.
Wiremesh cable trays are made out of steel wires of higher strength. The trays are manufactured by welding wires and creating a net. The net is further fabricated to form a channel followed by finishing process.
Generally used for low voltage and power cable installations where maximum cable freedom, side fill and speed to install are factors.
