Abstract

The invention discloses a wear-resisting and compression-resistant isolation cable. The wear-resisting and compression-resistant isolation cable comprises an outer sheath, wherein a plurality of compression-resistant bodies are distributed on the surface of the outer sheath in an annular direction; the compression-resistant bodies are integrally connected on the outer sheath, and the outer sides of the compression-resistant bodies are coated with a wear-resisting material structural layer; the wear-resisting material structural layer is fixed on the compression-resistant bodies; a general metal shielding layer is arranged in the outer sheath; the general metal shielding layer is connected with the outer sheath in a sealing manner; a fireproof isolation sleeve is arranged in general metal shielding layer; the fireproof isolation sleeve is fixed on general metal shielding layer; and flame-retardant fillers are arranged between the fireproof isolation sleeve and the general metal shielding layer. By virtue of the wear-resisting and compression-resistant isolation cable, the problem of surface wearing in dragging can be effectively avoided, and replacing frequency is lowered; in addition, the cable has the compression resistance effect and can bear certain gravity, so that conditions of cable deformation caused by extrusion can be reduced; and meanwhile, the cable has shielding and flame-retardant effects and higher safety coefficient.

Description

technical field [0001] The invention relates to a cable, in particular to a wear-resistant and pressure-resistant isolation cable. Background technique [0002] Fire-resistant cables refer to cables that can maintain safe operation for a certain period of time when the fire source is burning. The national standard GB / T12666.6 divides the fire resistance test into two grades, A and B. The temperature of the fire source is 750 ~ 800 ℃, and the continuous fire supply time is 90 minutes. During the whole test period, the sample should withstand the rated voltage value specified by the product, and keep the circuit unblocked. At present, most of the fire-resistant cables at home and abroad are magnesium oxide mineral insulated fire-resistant cables and mica tape wrapped fire-resistant cables. The structure of the magnesium oxide mineral insulated fire-resistant cable is made of an electrical copper rod as the conductor, a seamless copper tube as the sheath, and the sheath is fil...
