Abstract

The invention discloses an anti-tensile and inflaming retarding flexible cable. The anti-tensile and inflaming retarding flexible cable consists of two conductor cable core groups, two metal hoses and four outer protection layers, wherein the metal hoses are silver-plated aluminum metal hoses; the four outer protection layers comprise a silver-plated nickel strip screening layer, a silicone rubber insulation layer, a silver-plated nickel strip armor layer and a low-smoke zero-halogen polyolefin jacket layer, which are sequentially arranged from inside to outside; the two conductor cable core groups and the two silver-plated aluminum metal hoses are uniformly coated inside the silver-plated nickel strip screening layer in an extrusion manner. The cable has the advantages of light weight, four protection layers, long service life, high-temperature resistance, inflaming retarding property and acid and base prevention, and can be widely applied to petrochemical fields and the like.

Description

A kind of tension flame-retardant flexible electric cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of tension flame-retardant flexible electric cable.

Background technology

Cable is widely used in the every field such as people's lives, industrial production, so the consumption of cable is huge especially, also particular importance, also can be very high to the requirement of quality, but in every field, the quality purposes of cable is required it is different, as at oil and chemical field productive power cable, just require that cable has excellent acid and alkali-resistance, heat-resistant fireproof, could be durable in use, satisfy the demand.

Summary of the invention

In order to increase the practicality of prior art, the object of this invention is to provide a kind of heat-resistant fireproof, long-lived tension flame-retardant flexible electric cable.

The present invention takes following technical scheme to realize: a kind of tension flame-retardant flexible electric cable, it is by conductor cable core group, metal hose and four layers of external protection composition, conductor cable core group is set to two groups, conductor cable core group is by a silver coated aluminum conductor, four silver-plated nickel conductors, four silver-plated copper conductors, one deck aluminium strip armour and one deck polyvinyl chloride insulation layer composition, described aluminium strip armour is extruded in outside silver coated aluminum conductor, four silver-plated nickel conductors are extruded between described aluminium strip armour and polyvinyl chloride insulation layer, four silver-plated copper conductors are extruded in polyvinyl chloride insulation layer inside, metal hose is silver coated aluminum metal hose, be set to two, every root silver coated aluminum metal hose outer wrapping one deck teflon insulation layer, four layers of external protection are followed successively by silver-plated nickel strap screen from inside to outside, silicone rubber insulation layer, silver-plated nickel strap armour and low-smoke halogen-free polyolefin restrictive coating, two groups of conductor cable core groups and two silver coated aluminum metal hoses are all evenly extruded in silver-plated nickel strap screen inside.

The present invention has following beneficial effect in sum: this cable weight is light, and pull resistance is strong, and have four layers of protective layer, durable in use, have heat-resistant fireproof, the advantage of acid and alkali-resistance, is widely used in field of petrochemical industry.
