Wear resistant and heat resistant cable

Abstract

A wear resistant and heat resistant cable disclosed by the present invention belongs to the cable field and is composed of a cable core and a protection layer. The cable core is located in the center of the protection layer, and the protection layer is arranged into an inner layer, an intermediate layer and an outer layer. The inner layer is an insulating layer, and the insulating layer is made of a crosslinked polyethylene material. The intermediate layer is a heat insulation layer, and the interior of the heat insulation layer is filled with asbestos. The outer layer is a wear resistant layer, and the wear resistant layer is made of rubber. The wear resistant and heat resistant cable provided by the present invention can be used normally at a region of which the temperature is not a normal temperature because of the heat insulation layer, and the outer layer of the cable is equipped with the wear resistant layer, so that the cable can be protected from being damaged on a bad condition.

Description

technical field [0001] The invention relates to the field of cables, in particular to a wear-resistant and heat-resistant cable. Background technique [0002] At present, wires and cables are relatively common equipment in the fields of electric power and communication, and cables are also used in various occasions. However, in extremely cold or extremely hot areas, the cables in the prior art cannot meet their requirements, and often Because the conductivity of the cable is too high and too low, the conductivity of the cable changes greatly, and in the construction site, or outdoor laying and other places, the wire and cable are often dragged around, and they have to contact and rub frequently with the objects on the bottom surface. Just cause the wear and tear of the outer surface of electric wire and cable to varying degrees, especially in the relatively bad place of condition, the wear and tear degree of electric wire and cable is heavier, even causes unusable result. ...

[0002] At present, wires and cables are relatively common equipment in the fields of electric power and communication, and cables are also used in various occasions. However, in extremely cold or extremely hot areas, the cables in the prior art cannot meet their requirements, and often Because the conductivity of the cable is too high and too low, the conductivity of the cable changes greatly, and in the construction site, or outdoor laying and other places, the wire and cable are often dragged around, and they have to contact and rub frequently with the objects on the bottom surface. It leads to different degrees of wear on the outer surface of the wire and cable, especially in places with harsh conditions, the wear of the wire and cable is heavier, and even leads to unusable results.
