Safety protection measures when using Guangxi wire cable

1. When the Guangxi cable is crossed, the high-voltage cable should be under the low-voltage cable. If within 1m before after the intersection, one of the cables is protected by pipes separated by partitions, the minimum allowable distance is 0.25m.Guangxi cable

2. When the cable is close to crossed the heating pipe, if there are thermal insulation measures, the small distances of parallel cross are 0.5m 0.25m respectively.

3. When the cable crosses the railway highway, there should be pipeline protection. The protection tube should extend 2m the track road.

4. The distance between the cable the foundation of the building should ensure that the cable is buried outside the water of the building; when the cable is introduced into the building, there should be pipeline protection, the protection pipe should also extend beyond the water surface of the building.Guangxi wire cable

5. The distance between the directly buried cable the general grounding device should be 0.25~0.5m; the buried depth of the directly buried cable should generally be less than 0.7m, should be buried below the frozen soil layer.

With the rapid development of power cable buried laying projects, higher requirements are put forward for cable protection. The cable protective sleeve is made of polyethylene PE steel pipe, which is pretreated by sandblasting, shot blasting, dipping painting, heating curing. Crafted. It is a commonly used electrical insulating tube used to protect wires cables. It is widely used because of its good insulation performance, high chemical stability, no rust, no aging, adaptability to harsh environments.

Protecting the cable with a cable cover can achieve the following advantages:

1. It has good corrosion resistance long service life, can be used in humid saline-alkali areas.

2. Flame retardant heat resistant. It can be used for a long time at a high temperature of 130 degrees without deformation, it will burn in case of fire.

3. High strength high rigidity. It is used for direct burial under the roadway without adding a concrete protective layer, which can speed up the construction progress of the cable project.

4. The cable protective sleeve has a certain flexibility, whether it is a pipe a pipe fitting, it can resist the damage caused by external pressure foundation settlement.

5. Good anti-interference performance to external signals.

6. The inner wall is smooth will scratch the cable. The design adopts socket connection method, which is convenient for installation connection. The rubber sealing ring seal at the joint only adapts to thermal expansion contraction, but also prevents sediment entering.Guangxi cable manufacturer
