The existing CFRP carbon thread protective sleeve of Weifang manufacturer is 100mm power pipe

  Brief introduction of CFRP carbon threaded protective sleeve: carbon threaded pipe is a new type of power cable protective pipe produced by basic forming and unique rotary forming technology with high-density polyethylene and modified carbon as the main raw materials
With its unique spiral shape, it has many advantages, such as high strength, high toughness, corrosion resistance, high temperature resistance, high insulation resistance, good flame retardancy, light weight, long service life, not easy to deformation, etc
the product is widely used in urban street lamp line buried engineering, electrified railway power, communication cable laying buried engineering, highway power The construction and reconstruction project of communication facilities, the construction project of residential quarters and the buried cable project of parks and large entertainment places are the most ideal buried cable sheath pipes at present
1、 Construction method:
1
Selection of carbon pipe diameter
It shall be selected according to cable outer diameter, allowable voltage, current and other engineering conditions

2
Trench excavation
According to the regulations of relevant departments and user requirements, the width and depth of trench excavation shall be determined according to the number of cables laid
The distance between pipes and trenches is 50mm, and the distance between pipes is 30mm

3
Laying
After putting the carbon pipe into the ditch, the place with large bending shall be sealed with cement to prevent it from winding or extrusion
At the junction of two protective sleeves, the protective sleeve pipe head must be built with bricks and fixed with cement

4 connection
When two carbon pipes need to be butted, first screw the joint to one end of the connected pipe, then screw it back to the other end of the connected pipe, and then wrap it with PVC sealing tape

5
Backfilling after the carbon pipe is laid as required, it can be backfilled with the original soil during trench excavation, and the backfill shall be compacted
