Cable tray

Cable trays are divided into trough, tray, ladder, and network formats, and are composed of brackets, support arms, and mounting accessories. The bridge in the building can be erected independently, or it can be attached to various structures (structures) and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. , Installed in the open-air bridge outside the building.
Features:
The full name of a rigid structural system with tightly supported cables (such as bridges) is composed of trough, tray, or stepped straight line sections, bends, tees, crosses, and supporting arms (arm brackets), hangers, etc. . Shishang Bridge has been continuously recognized by the market and accepted the localization efforts of the cable bridge industry. The product uses high-quality cold-rolled steel. The product has received wide attention. The product uses high-quality cold-rolled steel. Fireproof paint, baking paint, etc.
Product number
1. Cascade cable tray
CQ1-T stepped cable bridge is improved and designed according to relevant domestic and foreign materials. It has the advantages of light weight, low cost, unique shape, convenient installation, heat dissipation and good ventilation. It is suitable for laying large diameter cables in general, and is suitable for laying high and low voltage power cables.
2.Tray type cable tray
Tray type cable tray is the most widely used in petroleum, chemical, light industry, telecommunications and other aspects. It has the advantages of light weight, large load, beautiful appearance, simple structure and convenient installation. It is suitable for both power cable installation and control cable laying.
3.Slotted cable tray
The trough cable tray is a fully enclosed cable tray. It is most suitable for laying computer cables, communication cables, thermocouple cables, and control cables for other highly sensitive systems. It has a good effect on shielding interference of control cables and protection of environmental cables in heavy corrosion.
The advantages and disadvantages of the step type, tray type and trough type cable bridge: the step type bus bridge has good ventilation performance, and is not dustproof or anti-interference. Slot-type and tray-type cable trays are dustproof and anti-interference.
4.Long-span cable bridge
At present, large-span cable trays are generally assembled from pultruded glass fiber reinforced plastic profiles, which are suitable for power cables, control cables, lighting cables and accessories. Compared with iron bridges, it has a long service life (generally designed life is 20 years), easy installation and low cost (the proportion is only 1/4 of carbon steel, no fire is required during construction, and the length of a single bridge can reach 8 Meters, or even longer), convenient cutting, no maintenance required, etc.
5.Combined cable tray
Combined cable tray is a new type of bridge tray, and it is the second generation product in the cable tray series. It is suitable for the laying of various projects, various units and various cables. It has the characteristics of simple structure, flexible configuration, convenient installation and novel form.
As long as the combined cable tray adopts three basic types with a width of 100, 150, and 200mm, it can form a cable tray of the size you need. It does not need to produce accessories such as bends, tees, etc., and can be turned, widened, Point up and down. In any position, it can be drawn out with a pipe without drilling or welding. It is not only convenient for engineering design, but also convenient for production and transportation, and more convenient for installation and construction. It is the most ideal product in cable trays.
