Abstract

The invention discloses an LSZH flame retardant environment-friendly flexible cable which is composed of nickel conductor cable cores, an EPR insulating layer, a copper strip shielding layer, an aluminium strip armor layer, a polyester fiber layer, a butyronitrile insulation layer and an LSZH polyethylene sheath layer. Twenty four sets of nickel conductor cable cores are arranged to be twisted together and then covered with the EPR insulating layer, the copper strip shielding layer is wrapped outside the EPR insulating layer, the aluminium strip armor layer is wrapped outside the copper strip shielding layer, the polyester fiber layer is wrapped outside the aluminium strip armor layer, and the butyronitrile insulation layer is wrapped outside the polyester fiber layer. The LSZH flame retardant environment-friendly flexible cable is low in mounting and laying temperature, long in service life, environmentally friendly and capable of not polluting the environment, has the advantages of high temperature resistance, good insulation and softness, and meanwhile has the advantages of being excellent in electrical stability in a high-temperature environment and excellent in magnetic disturbance prevention performance.

Description

A kind of low-smoke non-halogen flame-retardant environmental protection flexible cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of low-smoke non-halogen flame-retardant environmental protection flexible cable.

Background technology

Cable refers to the wire of conduction current, be widely used in petrochemical industry, metallurgical generating, square, tunnel every field, these fields require all high to the indices of cable, heat-resisting such as requiring to have, insulation, softness, diamagnetic interference, tension is firmly durable, and the excellent and characteristic that conducts electricity very well of heat-resisting quantity, just can ensure 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, there is softness, good insulation preformance, the low-smoke non-halogen flame-retardant environmental protection flexible cable of resistant to elevated temperatures advantage.

The present invention takes following technical scheme to realize: a kind of low-smoke non-halogen flame-retardant environmental protection flexible cable, it is by nickel conductor cable core, ethylene propylene rubber insulated layer, copper strip shielding layer, aluminium strip armour, layer of polyester fiber, butyronitrile insulating barrier and low smoke and zero halogen pe sheath layer composition, described nickel conductor cable core is provided with 24 groups and wraps up the ethylene propylene rubber insulated layer of one deck outside twisting together, outside described ethylene propylene rubber insulated layer, wrap up one deck copper strips screen, outside described copper strip shielding layer, wrap up one deck aluminium strip armour, outside described aluminium strip armour, wrap up one deck layer of polyester fiber, outside described layer of polyester fiber, wrap up one deck butyronitrile insulating barrier.

Described aluminium strip armour inside is extruded with 16 tinned copper conductors.

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 diamagnetic interference is excellent simultaneously.
