along withpower cable The rapid development of underground laying projects has put forward higher requirements for cable protection. Cable protection sleeves are made of polyethylene PE and high-quality steel pipes through sandblasting and shot blasting pre-treatment, immersion or coating, and heating and curing processes. It is the most commonly used electrical insulation tube for protecting wires and cables. Due to its excellent insulation performance, high chemical stability, non rusting, non aging, and adaptability to harsh environments, it has been widely used.

The use of cable protection sleeves to protect cables can achieve the following advantages: 1. Good corrosion resistance, long service life, and can be used in humid and saline alkali areas. 2. Flame retardant and heat-resistant, can be used for a long time at a high temperature of 130 degrees without deformation, and does not burn when exposed to fire. 3. High strength and rigidity. Used for direct burial under the roadway without the need for a concrete protective layer, it can accelerate the construction progress of cable projects. 4. Cable protection sleeves, whether made of pipes or fittings, have a certain degree of flexibility and can resist damage caused by external pressure and foundation settlement. 5. Has good resistance to external signal interference. 6. The inner wall is smooth and does not scratch the cable. The design adopts a plug-in connection method for easy installation and connection. Adding rubber sealing rings at the joint not only adapts to thermal expansion and contraction, but also prevents mud and sand from entering.
