Abstract

The invention discloses an armoured shielding tensile flexible cable for a tunnel square. The armoured shielding tensile flexible cable is composed of aluminum alloy conductor cable cores, a polytetrafluoroethylene-propylene insulation layer, a nickel strip armour layer, a nickel strip shielding layer and an aluminum strip armour 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 inside the polytetrafluoroethylene-propylene insulation layer in an extruded mode, the polytetrafluoroethylene-propylene insulation layer is wrapped by the nickel strip armour layer, the nickel strip armour layer is wrapped by the nickel strip shielding layer and the nickel strip shielding layer is wrapped by the aluminum strip armour polyethylene sheath layer. The cable is low in installation and laying temperature, long in service life, environmentally friendly and free of environment 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

Square, a kind of tunnel shields tensile flexible cable with armouring
Technical field
The invention belongs to field of cables, relate in particular to square, a kind of tunnel armouring and shield tensile 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 square, tunnel of resistant to elevated temperatures advantage shields tensile flexible cable with armouring.
The present invention takes following technical scheme to realize: square, a kind of tunnel armouring shields tensile flexible cable, it is by aluminium alloy conductor cable core, polytetrafluoroethyl-ne propylene insulating barrier, nickel strap armour, nickel strap screen 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 polytetrafluoroethyl-ne propylene insulating barrier inside, outside described polytetrafluoroethyl-ne propylene insulating barrier, wrap up one deck nickel strap armour, outside described nickel strap armour, wrap up one deck nickel strap screen, outside described nickel strap screen, 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 aluminium strip screens outside aluminium alloy conductor and form.
Described polytetrafluoroethyl-ne propylene insulating barrier inside is also extruded with two steel wire ropes.
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.
