Abstract

The utility model discloses a fire-resistant control cable. The fire-resistant control cable comprises conductors (1), a filling material (4), an inner sheath (5), a wrapping layer (6), an outer sheath (7) and a shielding layer (8), and is characterized in that copper wires are stranded to form the conductors (1); each conductor is sequentially coated with an insulating layer (2) and a glass fiber woven tape (3) from inside to outside; the filling material (4) coats the outer parts of the glass fiber woven tapes (3); the inner sheath (5) coats the outer part of the filling material (4); the wrapping layer (6) coats the outer part of the inner sheath (5); the outer sheath (7) coats the outer part of the wrapping layer (6); and the shielding layer (8) coats the outer part of the outer sheath (7). The control cable disclosed by the utility model has the advantages of good fire-resistant effects and high safety factors.

Description

A kind of fireproof control cable

Technical field

The utility model relates to a kind of control cables, particularly a kind of fireproof control cable.

Background technology

Along with the development of power industry, control cables is widely used in the fields such as heavy construction, chemical industry, oil, power plant, and these fields require very high to security performances such as fire prevention.Weak point of the prior art is that the current fire-resistant degree of control cables is not high, potential safety hazards such as being easily short-circuited, opening circuit in the situations such as high temperature, fire.

Utility model content

The purpose of this utility model is to provide a kind of high temperature resistant, fire-resistant control cables.

In order to reach above object, the technical solution adopted in the utility model is: a kind of fireproof control cable, and it comprises conductor (1), inserts (4), inner sheath (5), lapping layer (6), oversheath (7), screen (8); It is characterized in that, described conductor (1) forms by copper wire is stranded, and conductor (1) outside is coated with insulating barrier (2), fiberglass braided band (3) from inside to outside successively; Described inserts (4) is wrapped in fiberglass braided band (3) outside; Described inner sheath (5) is coated on inserts (4) outside; Described lapping layer (6) is coated on inner sheath (5) outside; Described oversheath (7) is coated on lapping layer (6) outside; Described screen (8) is coated on oversheath (7) outside.

Under better enforcement state, described insulating barrier (2), inner sheath (5), oversheath (7) adopt polytetrafluoroethylmaterial material to make.

Under better enforcement state, described screen (8) adopts tinned copper wire to make.

The beneficial effects of the utility model are to provide a kind of fire-resistant effective, control cables that coefficient of safety is high.

Accompanying drawing explanation

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

At the numerical reference described in Figure of description, be expressed as: 1, conductor; 2, insulating barrier; 3, fiberglass braided band; 4, inserts; 5, inner sheath; 6, lapping layer; 7, oversheath; 8, screen.

Embodiment

In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection range of the present utility model.

Referring to Fig. 1, a kind of fireproof control cable, it comprises conductor 1, inserts 4, inner sheath 5, lapping layer 6, oversheath 7, screen 8; Described conductor 1 forms by copper wire is stranded, and conductor 1 outside is coated with successively from inside to outside insulating barrier 2, is fiberglass braidedly with 3; Described inserts 4 is wrapped in fiberglass braided 3 outsides of being with; Described inner sheath 5 is coated on inserts 4 outsides; Described lapping layer 6 is coated on inner sheath 5 outsides; Described oversheath 7 is coated on lapping layer 6 outsides; Described screen 8 is coated on oversheath 7 outsides.

Under better enforcement state, described insulating barrier 2, inner sheath 5, oversheath 7 adopt polytetrafluoroethylmaterial material to make.

Under better enforcement state, described screen 8 adopts tinned copper wire to make.
