It's becoming more common to see a lot of data and communication cabling crammed into a small space to meet bandwidth and throughput demands. To control the I2R temperature rise, all of this may necessitate powerful air conditioning, not to mention clean electric heat and ventilation where temperature control is critical. Thus there is huge demand and importance of cable tray in industries, and is also one of the main components suggested under government norms.
The cable tray is a fantastic tool for organizing all of these wires. A single, large cable tray installation can route a large amount of wiring by using a grounded metal barrier along the centerline to separate power wiring and data/communication cabling. It prevents the formation of a disorganized mass of conductors that is difficult to trace when changes or faults are needed. It's important to understand the difference between cable trays and raceways. A cable tray system, according to the NEC, is a unit or assembly of units or sections, as well as associated fittings, that forms a structural system for securely fastening or supporting cables and raceways. Raceways, on the other hand, are typically installed on a wall in a room where power and communications cables are terminated. Cable trays, which are usually found above or beneath raised floors, carry open wiring. They're used to get cables from the source to where they'll be used.
Because the cable tray follows the room's perimeter, power and data conductors can enter and exit at various points, then travel through the raceway to their destinations. A listed cable tray clamp or adapter secures raceways terminating at a tray to the cable tray system. Cable trays come in a variety of sizes, styles (such as ladder, ventilated trough, ventilated channel, solid bottom, and similar structures), and materials (metal and non-metal). The cable tray is one of the permitted types of equipment grounding conductors if it is made of conductive material. Paint should be scraped off and jumper wires installed where sections bolt together to ensure ground continuity.
Ladder trays are typically used where larger bundles or heavier cables are present. Two side rails are connected by cross members, or rungs, on the ladder cable tray. The rungs serve as useful anchors for securing the cables. A trough cable tray is a prefabricated structure with side rails and a ventilated bottom. The ventilated trough cable tray provides better cable support than the ladder type, but the difference is minor. Because drooping fiber-optic cables can degrade system performance, solid-bottom cable trays are frequently used in fiber-optic cable installations. However, choosing solid-bottom trays is primarily motivated by the desire to reduce electromagnetic/radio-frequency interference or to protect sensitive circuitry.
Cable trays are a type of mechanical support for electrical cables that are used for power distribution, control, and communication. They're ideal for running large amounts of power or data cables overhead or beneath the floor. Cable trays come in a variety of shapes and sizes, and some regulations necessitate the use of specific accessories such as sides or covers. Steel, aluminum, or fiber reinforced plastic can be used. When looking at different types of cable trays for your machine or customer facility, it's important to know what cables you'll be installing and how long they'll run.
Cable fires can spread along a cable tray within a structure if combustible cable jackets catch fire. This can be easily avoided by using fire-resistant cable jackets or fireproofing coatings on installed cables. Because such fireproofing measures may reduce the heat dissipation of installed cables, heavy coatings or long fire-stops may necessitate a change in cable current ratings. Because cable trays are frequently installed in difficult-to-reach places, regular house cleaning is essential for safety. If the trays are not checked and kept clean on a regular basis, flammable dust and clutter can build up. Combustibility of plastic and fiberglass reinforced plastic
