Of course, the armored high-voltage cable is mainly used for being buried in the ground, can resist the compression with high strength on the ground, and can prevent other external force from damaging. The cable crush caused by the cable thermal expansion results in a breakdown. When the load of the crosslinked cable is high, the temperature of the wire core rises, the cable expands under heat, the cable is propped against the vertical surface of the bracket at the turning position in the tunnel, the creep force of the cable is very large when the cable is operated under a large load for a long time, the vertical surface of the bracket breaks the outer sheath and the metal sheath of the cable, and the cable is extruded into the insulating layer of the cable to cause the breakdown of the cable. The cable sleeve is also called as a protection tube and a conduit, and is a pipeline for protecting wires and cable wiring in electrical installation, and allows the wires and the cables to be penetrated and replaced. The cable sleeve is a novel sleeve material which is popularized and used in the power engineering.
