Abstract

The invention discloses a metallurgical electric power environmental protection flexible cable which is formed by grounding cable cores, a nonmagnetic metal armor layer, a tinning aluminum wire shielding layer, an FEP insulating layer, a polyester fiber layer, a carbon fiber band layer and an aluminum strip armor polythene sheathed layer. Seven sets of the grounding cable cores are arranged, the seven sets of the grounding cable cores are packaged in the nonmagnetic metal armor layer in a squeezing mode, the nonmagnetic metal armor layer is wrapped by the tinning aluminum wire shielding layer, the tinning aluminum wire shielding layer is wrapped by the FEP insulating layer, and the FEP insulating layer is wrapped by the polyester fiber layer. The cable has the advantages of being low in temperature during installation and laying, long in service life, environmentally friendly, free of pollution to the environment, resistant to high temperature, good in insulativity, soft, and excellent in electrical stability and conductivity in the high-temperature environment.

Description

A kind of metallurgical power environment protection flexible cable of using

Technical field

The invention belongs to field of cables, relate in particular to a kind of metallurgical power environment protection flexible cable of using.

Background technology

Cable refers to the wire of conduction current, is widely used in every field, in the middle of metallurgy is used 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 of metallurgy, 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 metallurgy of resistant to elevated temperatures advantage power environment protection flexible cable.

The present invention takes following technical scheme to realize: a kind of metallurgical power environment protection flexible cable of using, it is by ground connection cable core, nonmagnetic metal armour, zinc-plated aluminium wire screen, perfluoroethylene-propylene insulating barrier, layer of polyester fiber, carbon fiber belt 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 nonmagnetic metal armour inside, outside described nonmagnetic metal 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 aluminium conductor 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.
