Cascade, tray cable tray (T, P) ladder, cable tray tray can be widely used in petroleum, chemical, electric power, light industry, television, telecommunications, coal and other cabling. The utility model has the advantages of beautiful appearance, simple structure, convenient installation (heat dissipation, good air permeability, etc.). Ladder type cable tray applicable to the requirements of the power cable, also applies to the laying of control cable and is also available in the partition with a layer of cable bridge laying power cables and control cables. Cascade, tray cable bridge surface treatment points for electrostatic spray, galvanized, hot-dip zinc and zinc spraying four and can be used for different environments and in severe corrosion environment should be for a special anti-corrosion treatment.

Existing network bridge open structure can not only let the ventilation and heat dispersion of the maximum range of the cable, save energy, optimize the performance of the cable and can prevent the accumulation of water, dust, debris, bacteria breeding is not easy, more clean, reduce the risk of fire or other security hazards. These unique features to the Chinese customers a surprise. Summary down: light weight, light 30% - 60% than the traditional bridge; 90% open space; high mechanical strength, be convenient to shear; can give full play to your imagination free configuration style; without screws and nuts; data cable design accessories; with a convincing carrying capacity; for customers to save space and time, than traditional bridge to save the installation time of 1 / 3; unique bending method, fast and beautiful; at 1000 degrees Celsius temperature can also be stay for 90 minutes, safety protection tray is certified the largest tray and so on.

Fireproof glass steel cable tray mainly made of glass fiber enhanced materials and inorganic adhesive composite fireproof board and metal skeleton composite and other fireproof material. Outer fire paint, fireproof cable tray in the event of a fire will not burn, thus blocking the spread of fire, has the extremely good of fire retardant effect, and with fire, oil resistance, corrosion resistance, non-toxic, non polluting, convenient installation and overall, reasonable structure, use, long service life and beautiful, cable installation in the cable tray, the environment clean and tidy, convenient cleaning. The design of cable tray should be considered closed bridge. Intelligent building weak electricity system, there are usually more information monitoring and communication facilities such as Ba building automation) OA office automation) Ca Communication Automation) and other corresponding system composition, Ba, for example, in addition to the power supply of the building itself, for drainage, air conditioning, elevator and parking and other facilities equipped with necessary information monitoring and SA security automation FA) Fire Automation) and several subsystems to achieve system integration or part of the system integration, cable tray surface anti-corrosion technology have a variety of ways, commonly used coating door is metal and organic and inorganic matter three categories. Metal method is divided into five kinds, plating, powder coating, spray, hot dip, metal coating, organic coating for a variety of resin and its mixture of inorganic coating is composed of a variety of chemical substances. These coatings are based on environmental conditions and engineering requirements of the configuration of science, and the thickness of the coating and adhesion, etc. also should be taken into account.
