Today, we are here to briefly introduce relevant knowledge about Trough Cable Trays. We believe many people are not familiar with them, so let's take a look!

Trough cable tray is the full name of a rigid structural system that supports tight connections between trays, consisting of straight sections, curved sections, components, arms, and ladder hangers. The connection resistance between tray ends shall not exceed 0.00032 ohms, and the grounding holes shall have the insulation coating removed.

For the comprehensive wiring of trough cable trays, a necessary distance shall be maintained between the cables and nearby electrical equipment such as motors and power transformers that may generate high-level electromagnetic interference. They shall not be laid in parallel with the following pipelines. When unavoidable, the position of the cable tray shall meet the following requirements or corresponding protective measures shall be taken.

Trough Cable Trays

Trough cable trays adopt measures such as applying fire-resistant coatings on the surface of the trays and their supports/hangers, and their overall fire resistance performance shall meet the requirements of relevant national specifications or standards. They have good effects on shielding interference of control cables and protecting cables in heavily corrosive environments.

Trough cable tray products can effectively meet the requirements of engineering environmental protection and durability. Moreover, the use of cable trays can effectively ensure the progress of our daily life. "Trough metal raceways" have the advantages of light weight, low cost, convenient installation, good heat dissipation and air permeability, etc.

It is usually suitable for laying cables with large diameters, especially for laying high and low voltage power cables.
