With the rapid development of power cable buried laying engineering, higher requirements are put forward for cable protection. The cable protection sleeve is made of polyethylene PE and high-quality steel pipe, which is pre-treated by sandblasting and shot blasting, dipped or painted, and heated and cured. Crafted. It is the most commonly used electrical insulating tube for protecting wires and cables. It is widely used because of its good insulation properties, high chemical stability, no rust, no aging, and adaptability to harsh environments.
Using cable protection sleeves to protect cables can achieve the following advantages: 1. Good corrosion resistance, long service life, and can be used in humid saline-alkali areas. 2. It is flame-retardant and heat-resistant. It can be used for a long time at a high temperature of 130 degrees without deformation and will not burn in fire. 3. High strength and high rigidity. It is used for direct burial under the carriageway without adding a concrete protective layer, which can speed up the progress of the cable project construction. 4. The cable protection sleeve has a certain degree of flexibility, whether it is a pipe or a pipe fitting, and can resist damage caused by external heavy pressure and foundation settlement. 5. It has good anti-interference performance of external signals. 6. The inner wall is smooth and does not scratch the cable. The design adopts the socket connection mode, which is convenient for installation and connection. The rubber sealing ring seal at the joint not only adapts to thermal expansion and contraction, but also prevents mud and sand from entering.
