Introduction:

A cable typically consisting of several or sets of wires (at least two in each group) twisted together to form a rope like cable. Each set of wires is insulated from each other and often twisted around a center, with a highly insulated outer covering. Cables have the characteristics of internal electrification and external insulation.

The use of cable protective 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. 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 stiffness. Used for direct burial under traffic lanes without the need for concrete protection layer, it can accelerate the construction progress of cable projects. 4. Cable protective sleeves, whether in pipes or fittings, have a certain degree of flexibility and can withstand 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 method, which is convenient for installation and connection. Adding a rubber sealing ring at the joint not only adapts to thermal expansion and contraction, but also prevents mud and sand from entering.
