Abstract
The utility model discloses an armor flexible cable for a tunnel and square. The armor flexible cable for the tunnel and square is composed of an aluminum alloy conductor cable core, an FEP insulating layer, a nickel belt armor layer, a polyester fiber layer and an aluminum belt armor PVC sheath layer. Three groups of aluminum alloy conductor cable core are provided; the three groups of aluminum alloy conductor cable core are extruded in the FEP insulating layer; the FEP insulating layer is covered with one nickel belt armor layer; the nickel belt armor layer is covered with one polyester fiber layer; and the polyester fiber layer is covered with one aluminum belt armor PVC sheath layer. The armor flexible cable for the tunnel and square is low in laying temperature and long in service life, is environmentally friendly and free of pollution to environment, has the advantages of being resistant to high temperature, good in insulation performance, and great in softness, and has the characteristics of being great in electrical stability in the high temperature environment and good in anti magnetic interference.
Description
Technical field
The utility model belongs to field of cables, relates 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.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of environmental protection, has softness, good insulation preformance, square, the tunnel armoured soft cable of resistant to elevated temperatures advantage.
The utility model 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 utlity model has in sum following beneficial effect: this kind of cable installation temperature is low, long service life, 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.
