Sitong cable "quality first, customer supreme principle” invite you to pay attention to today's new information.

1. When the cable lines cross each other, the high voltage cable should be below the low voltage cable. If one of the cables is protected by a pipe within 1 m before and after the intersection or separated by a partition, the minimum allowable distance is 0.25 m.

2. When the cable is close to or intersected with the heat pipe, the minimum distance of parallel and intersected is 0.5m and 0.25m, respectively, if the insulation measures are taken.

3. when cables are crossed with railways or roads, they should be protected by pipes, and the protective pipes should extend beyond the track or 2m.

4. The distance between the cable and the foundation of the building should ensure that the cable is buried outside the scattered water of the building; when the cable is introduced into the building, it should be protected through the pipe, and the protective pipe should also be beyond the scattered water of the building.

5. The grounding distance between the cable directly buried in the ground and the grounding device should be 0.25-0.5m. The buried depth of the cable directly buried in the ground should not be less than 0.7m and should be buried under the permafrost.

Safeguard

With the rapid development of the power cable buried laying project and the higher requirements for cable protection, the cable protective sleeve is made of polyethylene PE and high quality steel pipe, pre-treated by sand blasting, dip or coating, and cured by heating. Crafted. It is the most commonly used electrical insulation tube for protecting wires and cables. Because it has good insulation performance, high chemical stability, no rust, no aging, and can adapt to harsh environments, it is widely used.

Protecting the cable with a cable protection sleeve can achieve the following advantages:

1, good corrosion resistance, long service life, can be used in wet salt and alkali.

2, flame retardant, heat resistance, can be used for a long time at 130 °C without deformation, not burning in case of fire

3. High strength and high rigidity. It can be used directly under the carriageway without the need to add a concrete protective layer.

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

5. It has good resistance to external signal interference.

6. The inner wall is smooth and does not scratch the cable. The design adopts a socket type connection for easy installation and connection. The rubber seal ring at the joint is suitable for both thermal expansion and contraction, and prevents mud and sand from entering.
