Abstract

The invention discloses an environmentally-friendly flexible power cable for a coal mine. The environmentally-friendly flexible power cable is composed of grounded cable cores, a tin-plated steel wire armored layer, a tin-plated aluminum wire shielding layer, an FEP insulating layer, a polyester fiber layer, a neoprene sheath layer and an aluminum tape armored polyethylene sheath layer. The number of the grounded cable cores is seven. The seven grounded cable cores are wrapped in the tin-plated steel wire armored layer in an extruded mode. The tin-plated steel wire armored layer is wrapped in the tin-plated aluminum wire shielding layer. The tin-plated aluminum wire shielding layer is wrapped in the FEP insulating layer. The FEP insulating layer is wrapped in the polyester fiber layer. The installing and laying temperature of the cable is low, the cable is long in service life and environmentally friendly and does not pollute the environment, and the cable has the advantages of being resistant to high temperature, good in insulating property and flexible. Meanwhile, the cable further has the advantages that in a high-temperature environment, electrical stability is excellent, and conductivity is excellent.

Description

A kind of Coal Electricity power environmental protection flexible cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of Coal Electricity power environmental protection flexible cable.

Background technology

Cable refers to the wire of conduction current, is widely used in every field, in the middle of Coal Electricity cable, indices to cable is had relatively high expectations, heat-resisting such as requiring to have, insulation, the characteristic of heat-resisting quantity and electric conductivity, just can be applied in the middle of field, colliery, ensures safety.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of environmental protection, have heat-resisting, good insulation preformance, the Coal Electricity power environmental protection flexible cable of resistant to elevated temperatures advantage.

The present invention takes following technical scheme to realize: a kind of Coal Electricity power environmental protection flexible cable, it is by ground connection cable core, tin plated steel wire armour, zinc-plated aluminium wire screen, perfluoroethylene-propylene insulating barrier, layer of polyester fiber, chloroprene rubber sheath layer and aluminium strip armouring pe sheath layer composition, described ground connection cable core is set to seven groups, seven groups of ground connection cable cores are extruded in tin plated steel wire armour inside, outside described tin plated steel wire armour, wrap up the zinc-plated aluminium wire screen of one deck, outside described zinc-plated aluminium wire screen, wrap up one deck perfluoroethylene-propylene insulating barrier, outside described perfluoroethylene-propylene insulating barrier, wrap up one deck layer of polyester fiber.

Described zinc-plated aluminium wire screen inside is extruded with 40 copper conductors.

Described layer of polyester fiber inside is extruded with 16 groups of nickel conductor thread cores.

The present invention has following beneficial effect in sum: this kind of cable installation temperature is low, long service life, and environmental protection is free from environmental pollution, have high temperature resistant, good insulating, soft advantage, also there is hot environment electric stability excellent, the feature that electric conductivity is excellent simultaneously.
