Trunking type cable tray, also known as trough type cable tray, is a fully enclosed cable tray. It is most suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has a good effect on shielding interference of control cables and cable protection in heavily corrosive environments.
The most direct difference between tray type cable tray and trunking type cable tray is that the trough type cable tray is fully enclosed, the tray type cable tray is that there are many waist shaped holes at the bottom of the cable tray, and the trough type cable tray and tray type cable tray are different at the bottom, with holes and no holes Trough type cable tray is not conducive to heat dissipation, and tray type cable tray is slightly better There are heat dissipation holes at the bottom of tray tray, but there are no in tray tray. Due to the heat dissipation holes, the thickness of tray tray plate should be thicker Trough type cable tray is most suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. Trough type cable tray has a good effect on shielding interference of control cables and cable protection in heavily corrosive environment. Tray type cable tray is widely used in petroleum, chemical industry, electric power, light industry, television, telecommunications and other fields. It has light weight, large load, beautiful shape, simple structure and convenient installation. It is suitable for both power cable installation and control cable laying The surface treatment of tray type bridge can be divided into galvanizing, electrostatic plastic spraying and hot galvanizing according to the needs of users. It can be used for special anti-corrosion treatment in heavy corrosive environment However, the applicable field of tray type cable tray is wider than that of trough type cable tray, and trough type cable is mainly suitable for laying wires and cables with small cross-section but a very large number, while tray type cable tray is mainly used for laying power cables with large cross-section but a relatively small number
