The cable tray is divided into a trough type, a tray type, a ladder type, a net format and the like, and is composed of a bracket, a support arm and a mounting attachment. The bridge inside the building can be erected independently, or it can be attached to various building (structure) and pipe brackets. It should be characterized by simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. , installed in the open-air bridge outside the building.
The full name of the rigid structural system with closely connected support cables (hereinafter referred to as bridge) consisting of trough, tray or step type straight section, bend through, tee, four-way assembly and support arm (arm bracket), hanger, etc. . The Shangyong Bridge has been continuously recognized by the market and accepted the localization of the cable tray industry. The products use high-quality cold-rolled steel sheets and have received extensive attention. The products are made of high-quality cold-rolled steel sheets. The surface processes include cold-galvanizing, hot-dip galvanizing and electrostatic spraying. Fireproof coatings, baking varnishes, etc.
1. The stepped cable tray CQ1-T stepped cable tray is improved 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 the laying of large diameter cables and is suitable for laying high and low voltage power cables. 2, tray cable tray tray cable tray is the most widely used in petroleum, chemical, light industry, telecommunications and other aspects. The utility model has the advantages of light weight, large load, beautiful appearance, simple structure and convenient installation. It is suitable for the installation of power cables and for the laying of control cables. 3. Trough cable tray The trough cable tray is a fully enclosed cable tray. It is ideal for laying computer cables, communication cables, thermocouple cables, and other control cables for highly sensitive systems. It has a good effect on the shielding interference of the control cable and the protection of the environmental cable in the heavy corrosion. Advantages and Disadvantages of Cascade, Pallet, and Trough Cable Tray: The stepped wire bridge has good ventilation performance, and is not dustproof or interference-proof. The trough and tray type wire bridges are dustproof and anti-jamming. 4, large span cable tray The current large span cable tray is generally assembled from pultruded FRP profiles, suitable for power cables, control cables, lighting cables and accessories. Compared with the iron bridge, it has a long service life (general design life of 20 years), easy installation and low cost (the specific gravity is only 1/4 of carbon steel, no need for moving fire during construction, the length of a single bridge can reach 8 Meters, even longer), easy to cut, no maintenance and other advantages. 5, combined cable tray combined cable tray is a new type of bridge, is the second generation of cable bridge series. It is applicable to 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 of widths of 100, 150 and 200mm, it can form a cable tray of your required size. It can be arbitrarily turned and widened according to the on-site installation without the need to produce accessories such as bends and tees. Divide and lead. In any part, no need to punch holes, welding can be taken out by the tube. It is convenient for engineering design, convenient for production and transportation, and more convenient for installation and construction. It is the most ideal product in the current cable tray.
