Cable Trays are Ideal for use in Home, Building, and other Construction sites

What is Cable Tray?

Cable trays are ideally used for building and construction purposes. Cable trays are used to hold up and distribute cables. Steel, plastic, aluminum, Fiberglass are mostly used to make cable trays.

These trays are easy to customize because of its variety in sizes and shapes. The user can choose from Straight, L-shape, T-shape, and X-shape cable trays that can also be mixed and matched. These different shapes of cable trays can be interconnected using common splice washer clamps. They all provide ease in cable routing because of its 2x4 inch grid and factory fabricated junction that cuts down time and cost of installation. Cable trays can be installed on ceilings, walls, or under raised flooring.

Importance of cable tray-

In any electrical installation, the structure type used to support, fasten, direct, and protect the installed wire and cable runs is critical. That's why choosing the appropriate pathway is so important.

Various places where cable trays are preferably used:

• Houses
• Stores
• Buildings

Types of cable tray available:

• Ladder
• Solid Bottom
• Trough
• Channel
• Wire Mesh
• Single Rail

Other types of cable tray include:

Solid Bottom Cable Tray Trough Cable Tray Channel Cable Tray Wire Mesh Cable Tray Single Rail Cable Tray

Perforated type cable tray

These various types of cable tray are used for varied and multiple purposes. The uses are varied and can be used extensively.

A cable tray normally is used and functions for the following purposes:

• Cable trays support cable the way that roadway bridges support traffic.
• A bridge is a structure that provides safe passage for traffic across open spans.
• Cable tray is the bridge that allows for safe transport of wires across open spans.
• Therefore, think of cable tray as the structural component of a building's electrical system.

Cable Trays can be used outdoor and because of their powder coating they are corrosion protected, however they do not have a specific approval and they should not be used in an environment where there is extreme salt content because it will eventually corrode.

The types of cables permitted by the 2005 NEC for installation in cable tray systems are indicated in Section 392.3 uses permitted, (a) Wiring Methods. They include:

• Power and Control Tray Cable (Type TC)—NEC Article 336
• Power Limited Tray Cable (Type PLTC)—NEC Sections 725-61(C) and 725.82(E) Instrument Tray Cable (Type ITC)—NEC Article 727
• Optical Fiber Cables—Article 770
• Fire Alarm Circuit Conductors—Article 760
• Communication Cables—Article 800
• Mineral Insulated (MI) Cable—Article 332
• Metal Clad (MC) Cable—Article 330
• Other cables, including those specially approved for installation in cable trays. Medium voltage (type MV) and single conductor cables in sizes 1/0 and larger are permitted with some restrictions in Industrial Establishments where qualified persons service the installation.

These guidelines permit engineering companies to select and install the necessary type of Cable tray. These regulations entrust proper usage and no misuse of the cable tray.
