Abstract

The utility model discloses a fireproof tensile explosion-proof cable. The fireproof tensile explosion-proof cable comprises conductors. Each conductor is formed by stranding pure nickel wires, and is sequentially covered by a silicone rubber insulating layer, a fluoroplastic insulating layer and a steel wire braided armor layer. Two conductors are stranded and then are covered by three galvanized steel belt armor layers to form a wire core. Two wire cores are stranded and then are covered by an aluminum interlocking armor layer to form a cable core. Nine wire cores are arranged around the cable core and then are bound through a plastic rubber belt, and are sequentially covered by a glass fiber fireproof layer, a fiber belt wrapping layer coated by a semi-conductive colloid, a non-woven fabric wrapping layer, and a nanoscale polyolefin fireproof sheath. A circular polyester material tearing rope is disposed between the glass fiber fireproof layer and the fiber belt wrapping layer coated by the semi-conductive colloid. The fireproof tensile explosion-proof cable is simple in structure, novel in design and low in cost, has good safety performance and reliability, long service life and high cost performance, and is waterproof and tensile.

Description

A kind of fire-resistant tension anti-explosion cable

Technical field

The utility model relates to cable technology field, relates in particular to a kind of fire-resistant tension anti-explosion cable.

Background technology

For the electric equipments such as fire-proof motor, its supporting anti-explosion cable major requirement reaches the following aspects requirement of explosion proof: cable can meet the long enough time and work under 180 degree hot environments, in addition under or extreme case special at some, can meet the short time normally to work under the high pressure conditions steam ambient that exceedes 180 degree.Existing fire-proof motor cable security poor reliability, useful life is short, and cost performance is low, needs to improve.

Utility model content

The utility model object is exactly the defect in order to make up prior art, and a kind of fire-resistant tension anti-explosion cable is provided.

The utility model is achieved through the following technical solutions:

A kind of fire-resistant tension anti-explosion cable, include conductor, described conductor forms by pure nickel tow strand, described conductor outside is coated with silicone rubber insulation layer successively, fluoroplastic insulation layer and steel wire woven armored layer, form core by being surrounded by three layers of galvanized steel strip armour after two conductor bundle strands, form cable core by being surrounded by aluminium strip lock armo layer after two core bundle strands, around cable core, be placed with nine cores and bundle by plastic adhesive tape, and be coated with successively glass fiber fireprotection layer in outside, scribble the fabric strip lapping layer of semiconductive colloid, nonwoven fabrics belting layer and the fire-resistant sheath of nanoscale polyolefin, at glass fiber fireprotection layer with scribble and be provided with round polyester material between the fabric strip lapping layer of semiconductive colloid and tear rope.

The utility model has the advantages that: the utility model is simple in structure, modern design, security reliability is good, long service life, cost performance is high, fire-resistant, waterproof tensile, cost is low.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment
