With the rapid development of buried power cable laying project, higher requirements are put forward for cable protection. Cable protection sleeve is made of polyethylene PE and steel pipe through sandblasting and shot blasting, dipping or coating, heating and curing process. It is a common type used to protect control cables. Because of its excellent insulation, chemical stability, anti-aging, anti-corrosion, and can adapt to harsh environments, it is widely used.



Using a cable protection sleeve to protect a cable can achieve the following advantages:

1, good corrosion resistance, long service life, can be used in wet saline-alkali zone.

2, flame retardant, good heat resistance, can be used at 130 degrees high temperature for a long time without deformation, in case of fire does not burn.

3, high strength, high stiffness. In ordinary areas, it can be directly buried in the ground without adding a concrete protective layer, which can speed up the project progress.

4, cable protection sleeve whether pipe or pipe fittings have a certain flexibility, can resist the damage caused by external pressure and foundation settlement.

5, with good resistance to external signal interference performance.

6, the inner wall is smooth, does not scratch the cable. The design adopts socket type connection mode, convenient installation connection. And the joints at both ends are sealed with rubber sealing rings, which can not only ensure its normal thermal expansion and contraction function, but also prevent other external debris from entering.

Storage method:

If the control cable is to be stored for a long time, the following considerations should be made according to the location of the cable:

1. Under the eaves. Cables should not be exposed to direct sunlight or high temperatures, and piping is recommended.

2. Exterior wall. Should pay attention to avoid the sun for a long time exposure to the wall and man-made damage.

3, in the pipe (plastic or metal). For pipeline storage, check the thermal conductivity and integrity of the pipeline in time.

4, suspension application/overhead cable. According to the requirements of the cable application, the appropriate fixing method is adopted according to the characteristics and whether the cable can be directly exposed to sunlight.

5, directly laid in the underground cable trench, this is to limit the environmental factors in a controllable range. The cable trench should be checked regularly to ensure that it meets the conditions of use.

6. Underground pipes. For the sake of future cable upgrades, auxiliary pipes are a better way to place cables. But the pipeline can not always keep dry or the right temperature, so the choice of cable should be considered in many aspects.
