Abstract

The invention discloses an insulating high-temperature resistant high-strength low-halogen smoke power cable, comprising a cable core, wherein the surface of the cable core is coated with an insulating layer, the surface of the insulating layer is coated with a mica tape layer, and the surface of the mica tape layer is movably connected with a rubber ball. As that mica belt lay is arranged, A micatape lay is directly wound or sheathed on that insulate layer, subject that cable core to flame retardancy, at the same time, the rubber ball and the filling layer can have certain cushioning and compression resistance, so that it passes through that radiation shielding lay, Flame retardant and wear resistant coatings, so that the cable core has certain radiation protection inside, Flame retardancy and wear resistance, At that same time, the steel re can reduce the damage under the condition of surface drag, and the flame retardant rub inside the flame retardant layer is filled with a halogen-free crosslinked polyethylene flame retardant material, which not only has bet flame retardancy characteristics, but also is environmentally friendly, so that halogen smoke is reduced, and the practicability of the insulated high-temperature resistance high-strength low-halogen smoke power cable is further enhanced.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an insulating, high-temperature, high-strength, low-halogen smoke power cable. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. [0003] In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the backbone lines of power systems, including 1-500KV and above various voltage levels, and various insulated power cables, but the cables currently on the market have disadvantages insufficient: [0004] 1. At present, it is mostly used in PVC insulated cables for its advantages of light weight, low price, good elect...
