By groove type, tray type or stepped straight segment, bend, tee, four-way components and bracket timbering (arm), hanger, etc have contact support the full name of the rigid structure of the cable system.
1, the cascade type cable tray
CQ1 -t cascade type cable tray is according to the relevant data at home and abroad and design improvements. It has light weight, low cost, does not have modelling, easy installation, heat dissipation, good ventilation, etc. He is suitable for general larger diameter of cable laying, suitable for high and low voltage power cable laying.
2, tray type cable tray
Tray type cable tray is petroleum, chemical industry, light industry, telecommunications, etc, one of the most widely used. It has light weight, large load, beautiful shape, simple structure, easy installation, etc. It is suitable for the installation of power cable, also suitable for control cable laying.
3, groove type cable tray
Groove type cable tray is a fully enclosed cable tray. It's apply to computer cable, communication cable, themocouple cable and other highly sensitive system, control cable, etc. It to control cable shielding interference and heavy corrosion protection environment in the cable, there is good effect.
Ladder type, tray type, slot type cable tray their respective advantages and disadvantages: Cascade type to collect ark with good ventilation performance, no dust, no interference. Groove type, tray type ark with dust, anti jamming performance.
4, large span cable tray
The current large span cable tray is generally made by pultrusion FRP profiles have been assembled, suitable for power cable, control cable, lighting cables and accessories. Compared with the iron bridge, has a long service life (general design life for 20 years), convenient installation and low cost (weight is only 1/4 of carbon steel, not hot in the construction, single bridge can be up to 8 meters in length, or longer), such as cutting convenient, do not need to maintain superiority.
5, combined cable tray
Combined cable tray is a new type of bridge, is the second generation of cable tray series products. It projects, all kinds of units, apply to all kinds of cable laying, it has simple structure, flexible configuration, easy installation, innovative forms, etc.
Combined cable tray as long as the 100, 150, 200 mm wide of three kinds of base type can be all you need to size of the cable tray, it does not need to produce fittings such as bending, tee can be according to the on-site installation any steering, widen, and lead the upward. In any place, do not need to punching, welding can be used in derivation. It is easy and convenient on engineering design, production more convenient transportation, installation, is the most ideal products in the cable tray.
