Cable troughs are straight and can be found everywhere.

Will use the wiring of the construction site. The length is usually 2 meters. Usually when you look up in a public parking lot, you will see these things, wires and cables are placed in this area. During construction there are many wires and cables to be led from one center to another, so cable bridges will be used at this time. 　　Cable ducts are used for laying cables. A common specification is 200mm wide * 100mm high and above, this is known as a tray.

The raw data are all galvanized steel, with a zinc coating on the steel surface for simple rust and corrosion protection. However, this galvanized layer turns white quickly when exposed to water and rusts when exposed to water for a long time. Therefore, it should be used indoors rather than outdoors. For outdoor use, the cable tray should be hot dip galvanized (hot dip galvanized), that is, “hot dip galvanized cable tray”, the galvanized layer reaches 67um or more or change to stainless steel cable tray and aluminum cable tray cable tray can also be sprayed on the outside surface, with a certain degree of waterproof and anti-corrosion ability, but also can be sprayed a variety of colors, more beautiful.

More beautiful.

Weak power project commonly used cable tray: trough bridge, tray bridge, aluminum alloy bridge and mesh bridge cable trough and cable trough is the difference between the cable trough and cable trough can be laid power cables. The cross-section and structure are different clogged wire channel boxes, uncovered cable channels and ladders all belong to cable channels. These three types of tower trays have different structures and different properties. For example, troughs are well protected, ladders are poorly protected, but ventilation and cooling are opposite.
