Mining fire-retardant corrosion-resistant woven cable

Abstract

The invention relates to a mining fire-retardant corrosion-resistant woven cable. The mining fire-retardant corrosion-resistant woven cable comprises a cable core and a protection sleeve which wraps the cable core; the cable core is a conductor, wherein a plurality of electric units wind together to form the conductor; every electric unit comprises a metal bare wire and an ethylene propylene rubber insulation layer which wraps the metal bare wire; the protection sleeve comprises a polycarbonate protection sleeve, a woven layer and a mica lapping layer from outside to inside; a fireproof heat insulation reinforcement part is arranged inside the cable core. According to the mining fire-retardant corrosion-resistant woven cable, the polycarbonate serves as an outer layer protection sleeve of the protection sleeve and accordingly the flame retardancy, the tensile performance and the corrosion resistance are good; the woven layer is a fiber woven layer and accordingly the underground oxidation is effectively prevented and the flame retardant effect is achieved; every ethylene propylene rubber insulation layer wraps the corresponding metal bare wire and accordingly the melting point is high, the flame retardancy is good, and the shielding effect is good; the fireproof heat insulation reinforcement part is arranged inside the cable core and accordingly the long-term use of underground vertical cables is facilitated and the deformation and the tearing of the underground vertical cables are avoided.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to a flame-retardant and anti-corrosion braided cable for mining. Background technique [0002] At present, with the continuous improvement of coal mine mechanization and automation, electric control technology has a very important meaning in coal mines. The cable is mainly composed of PVC outer sheath, because the PVC insulation and the PVC outer sheath are extremely flammable and will produce a large amount of hydrogen chloride poisonous gas to suffocate people, so the existing coal mine control soft cable Difficult to adapt to underground safety requirements. At the same time, when the mine cable is used for vertical laying in the mine, it will be deformed or torn after long-term use due to the heavy weight of the cable itself. The metal shielding layer of cables is often made of iron wire, which is prone to oxidation and rust in a dark and humid environment fo...

The cable is mainly composed of PVC outer sheath, because the PVC insulation and the PVC outer sheath are extremely flammable and will produce a large amount of hydrogen chloride poisonous gas to suffocate people, so the existing coal mine control soft cable Difficult to adapt to underground safety requirements

At the same time, when the mine cable is used for vertical laying in the mine, it will be deformed or torn after long-term use due to the heavy weight of the cable itself. The metal shielding layer of cables is usually made of iron wire, which is prone to oxidation and rust in a dark and humid environment for a long time, which affects its shielding effect
