Abstract

The invention discloses a high-temperature resistant sector conductor cable which comprises multiple tinned copper conductors. The tinned copper conductors are stranded to form three sector wire cores, the three sector wire cores are distributed in an annular structure, a Y-type nylon framework is arranged among the three sector wire cores, high-temperature resistant fiber filaments are lapped and overlapped on the outer surface of the Y-type nylon framework, an insulating layer covers the three sector wire cores, and a high fire resistant fiber band isolation layer, an alkali-free glass fiber cloth wrapping tape layer, a metal shielding layer and a sheath layer wrap the insulating layer in sequence. The high-temperature resistant sector conductor cable is ingenious in structure improvement, the sector wire cores are arranged compactly, the framework with the high-temperature resistant fiber filaments is arranged, and the high-temperature resistance performance and the mechanical properties of the cable are improved integrally.

Description

technical field

[0001] The invention relates to cables, mainly a high-temperature-resistant fan-core cable. Background technique

[0002] The cables used in coal mines should have good flame retardant and high temperature resistance, but at the same time, they must also have certain pressure resistance and maintain good overall mechanical properties, so as to be able to adapt to the coal mine environment; the inner core of existing high temperature resistant cables is buried in the within the high temperature material, but this still does not address its mechanical resistance to compression.

[0003] Traditional cable sheathing materials have insufficient tensile strength, impact strength, corrosion resistance, creep resistance and wear resistance. Contents of the invention

[0004] The technical problem to be solved by the present invention is to provide a high temperature resistant cable with ingeniously improved structure, compact arrangement of multiple fan-shaped cor...
