Integrated wiring projects, horizontal cabling subsystem, vertical main trunk cabling subsystem and complex wiring subsystem of construction materials in addition to the cable material, the most important thing is that tube slot and bridge.
steel tube
The steel pipe used in the dark compress system is welded steel pipe.
Plastic pipe is made of resin, stabilizer, lubricant and filling agent.
Currently used in telecommunication cable protection sleeve basically has the following products: PVC pipes (PVC - U tubes), high-density polyethylene pipes (HDPE pipe), double-wall corrugated pipe, tube, aluminous model multiple tube, silicon core pipe and concrete, etc.
The integrated wiring system usually adopts soft, hard polyvinyl chloride tube, and is a solid wall plastic pipe inside and outside.
The system protects the children's tubes
composite material pipe
The weight is light, the same diameter pipe weighs 1/3 of the steel pipe.
At the same time, it also has good flammability characteristics, small linear expansion coefficient, aluminum alloy has good electrical conductivity.
The metal detector can also detect the location of the aluminum plastic pipe and facilitate the repair and management of the pipes.
Silicon core pipe can be directly buried cable casing, permanent lubrication lining, the lining preset has a small friction coefficient, cloth cable, gas method in pipe fast, one-time wear line 500 ~ 2000 m in length, along the joint, manhole, hand hole.
Plastic trough is the integrated wiring project Ming pipe groove when a kind of widely used material, it is a tube with cover plate enclosed tank material, cover plate and tank through the slot and solutions.
PVC wire slot accessories
The bridge is divided into three types according to its structure: step, pallet and slot.
If the bridge is handled according to its surface craft:
Suitable for general use of normal environment.
It is suitable for use in the environment of acid, alkali and other strong corrosive gases.
Apply to the environment of suntan, dust.
Fully enclosed cable bridge is suitable for the control cables of computer cables, telecommunication cables, thermocouple cables and other high sensitive systems.
The step bridge space is decorated with a schematic design
Stent is a major part of the support cable bridge, it is made up of columns, column base, bracket, etc, can satisfy the different environment conditions of installation forms (suspension type, vertical type, unilateral, bilateral and multi-layer, etc.) of the bridge.
