In the process of construction, it is often applied to the cable maintenance pipe, but the detailed impact on the cable maintenance tube, each can clearly? The above business treasure for you to introduce what the cable maintenance tube and cable maintenance tube influence.
In the process of construction, it is often applied to the cable maintenance pipe, but the detailed impact on the cable maintenance tube, each can clearly?
The cable maintenance pipe is named as cable pipe, power cable pipe, cement cable pipe, power line pipe, power cable maintenance pipe and so on. Cable maintenance device inserted in the secondary communication cable and power line area, avoid power line disconnection attack forms a short circuit accident, cause communication cable and wire rope charged, in order to maintain cables, switches, circuit board, so that parts will not be burnt, also to sever impact of inevitable to the power line magnetic field interference.
At the same time the use of plastic cable maintenance maintenance cable can reach the following disadvantages of casing:
1, good corrosion resistance, long service life, can be used in saline and alkaline areas.
2 、 high ampacity of cable maintenance and low thermal resistance coefficient.
3, flame retardant, heat resistance is good, can be used at 130 degrees low temperature temporary use without deion, fire is not burning.
4, the use of cable maintenance tube, and between the cable friction coefficient is low, cable wear more convenient.
5, high strength, high stiffness. The utility model is directly buried under the driving way without adding a concrete maintenance layer, and can speed up the construction progress of the cable project.
6 、 the cable maintenance Pipe lengthens the well spacing, reduces the number of working wells and reduces the cost of the project.
7, plastic cable maintenance casing for pipe fittings are still has certain flexibility, can resist the external stress and foundation settlement caused by the destruction of.
8, with good anti signal interference function.
9, smooth inner wall, no scratches on the cable. The idea is to accept the plug in connection method and facilitate the device connection. Rubber seals are added at the discussion site to conform to both thermal expansion and cold shrinkage and to prevent mud penetration.
