Abstract
The invention discloses an armoured flexible cable used for a tunnel square. The armoured flexible cable used for the tunnel square is composed of aluminum alloy conductor cable cores, a polyfluorinared ethylene propylene insulating layer, a nickel strip armoured layer, a polyester fiber layer and an aluminum strip armoured polyethylene sheath layer. The number of the aluminum alloy conductor cable cores is three sets, the three sets of aluminum alloy conductor cable cores are arranged in the polyfluorinared ethylene propylene insulating layer in an extruded mode, the polyfluorinared ethylene propylene insulating layer is wrapped by the nickel strip armoured layer, the nickel strip armoured layer is wrapped by the polyester fiber layer and the polyester fiber layer is wrapped by the aluminum strip armoured polyethylene sheath layer. The cable is low in installation and laying temperature, long in service life, environmentally friendly and free of pollution, has the advantages of high temperature resistance, good insulation performance and good flexibility, and meanwhile, further has the advantages of being superior in high-temperature environment electrical stability and superior in magnetic disturbance resistance.
Description
Technical field
The invention belongs to field of cables, relate in particular to square, a kind of tunnel armoured soft 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, square, the tunnel armoured soft cable of resistant to elevated temperatures advantage.
The present invention takes following technical scheme to realize: square, a kind of tunnel armoured soft cable, it is by aluminium alloy conductor cable core, perfluoroethylene-propylene insulating barrier, nickel strap armour, layer of polyester fiber and aluminium strip armouring pe sheath layer composition, described aluminium alloy conductor cable core is set to three groups, three group aluminum alloy conductor cable cores are extruded in perfluoroethylene-propylene insulating barrier inside, outside described perfluoroethylene-propylene insulating barrier, wrap up one deck nickel strap armour, outside described nickel strap armour, wrap up one deck layer of polyester fiber, outside described layer of polyester fiber, wrap up one deck aluminium strip armouring pe sheath layer, described aluminium alloy conductor cable core is by 27 aluminium alloy conductors and be wrapped in 27 nickel strap screens outside aluminium alloy conductor and form.
Described perfluoroethylene-propylene insulating barrier inside is also extruded with an aluminum metal flexible pipe.
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.
