The bridge is a support for supporting and placing the cable. The bridge is widely used in engineering. It has the characteristics of wide variety, wide application, strong intensity, light structure, low cost, simple construction, flexible wiring, installation standard and beautiful appearance.
Basic classification:
Ladder type cable bridge
The CQ1-T type ladder type cable bridge is designed according to the relevant data at home and abroad. It has the advantages of light weight, low cost, different modeling, convenient installation, heat dissipation, good air permeability and so on. He is suitable for laying large cables with larger diameter and suitable for the laying of high and low pressure internal chain power cables.
Tray type cable bridge
Tray type cable bridge is widely used in oil, chemical, light industry, telecommunications and other aspects. It has the advantages of light weight, large load, beautiful shape, simple structure, easy installation and so on. It is suitable for the installation of power cables, and is also suitable for the laying of control cables.
Grooved cable bridge
Trough cable tray is a fully enclosed type cable tray, which is suitable for laying computer cable, communication cable, thermocouple cable and other highly sensitive system control cables, the cable control cable shielding interference and heavy corrosion environment protection in a good effect. The shield of the trough type cable bridge is supplied with the slot body, and the other accessories are common to the ladder type and tray type bridge. Other specifications if users need trough cable tray to map a letter or Mianqia order.
Large span cable bridge
The large span remittance bridge can be divided into ladder type, tray type and slot type. The ladder type remittance bridge has good ventilation performance, no dust prevention and interference. The surface treatment of pallet cable bridge can be divided into three types, zinc plating, electrostatic spraying and hot-dip galvanizing according to users' needs. It can be specially treated in heavy corrosive environment. Slotted and pallet type remittance bridges have dustproof and anti-jamming performance. Trough cable tray is a fully enclosed type cable tray, with cover, use a small amount of bolts, it is suitable for laying computer cable, communication cable, thermocouple cable and other highly sensitive system control cables, cable to control cable shielding interference and heavy corrosion environment protection in the very good effect.
