Generally speaking, the cable tray is used to protect the cable, and the cable warp is placed inside to play a protective role. Isn't it OK to use trunking for cable? Cable tray is specially used for laying large diameter cables, and wires are laid in trunking. Therefore, cable trays usually appear in some environments with high safety requirements. The appearance and shape of cable trays made of different materials are the same, but the specifications and sizes are different.            

(1) Determine the bridge width, the number of layers, the type and spacing of support points, and the distribution of cables on each layer of bridge.

(2) Calculate the uniformly distributed load (kn/ m2) of each layer of cable, and preliminarily determine the model and specification of the bridge.

(3) The bridge strength is checked and calculated according to the maximum total uniformly distributed load value of the cable

This product is aluminum alloy trough cable tray, which 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 the shielding interference of control cables and the protection of cables in heavy corrosive environment. Type selection design of cable tray: strong and weak current lines shall be laid in separate slots. When strong and weak current intersect in junction boxes (boxes), metal separation plates must be used to separate them. Strong and weak current conductors shall not be directly contacted in the trunking. All kinds of wiring in the ground trunking can only be connected at the outlet of the junction box. During the construction and installation of ground trunking, all trunking pipes are required to be connected into a reliable grounding whole.
