Abstract

The utility model relates to a fireproof cable, comprising a conductor part, an insulating layer, an inner protecting bush, an armoring layer and an outer protecting bush, wherein the insulating layer covers the peripheral side of the conductor part; the inner protecting bush covers the peripheral side of the insulating layer; the fireproof layer covers the peripheral wall of the inner protecting bush; the armoring layer covers the peripheral side of the fireproof layer; the outer protecting bush covers the peripheral wall of the armoring layer, wherein the conductor part is internally provided with a plurality of conductors covered by fireproof inflaming retarding materials; and a filler is filled into a gap between each two conductors. According to the fireproof cable disclosed by the utility model, the fireproof layer is arranged on the inner protecting bush so as to effectively prevent or prolong the influences of fire behaviors on the cable; and particularly, the fireproof inflaming retarding materials arranged at the peripheral side of the conductors are matched so that the fireproof performance of the cable is more excellent, and the effect that the safety performance is more obvious is represented in special environments including a fire disaster scene and the like.

Description

A kind of fire-type cable

Technical field

The utility model relates to a kind of fire-type cable.

Background technology

As everyone knows, cable is as the supporting body of conduction, and the quality of its insulation property and fire protecting performance directly has influence on the inferior bad of cable; The cable of producing on the existing market can both satisfy the basic instructions for use of relevant insulating properties basically; Yet, for the fireproofing of cable performance, especially under the particular surroundings of scene of fire; Often especially can fire-resistant fireproof cable; And then result in greater loss, also just therefore, the cable that does not have fire line is worried by people as potential potential safety hazard always.

Summary of the invention

The purpose of the utility model is to overcome the defective of prior art, provides a kind of security performance good fire-type cable.

For realizing above-mentioned purpose; The utility model adopts a kind of fire-type cable, comprises conductor part, insulating barrier, inner sheath, fireprotection layer, armour, oversheath, and said insulating barrier is coated on all sides of said conductor part; Said inner sheath is coated on all sides of said insulating barrier; Be coated with fireprotection layer on the said inner sheath periphery wall, said armour is coated on all sides of said fireprotection layer, and said oversheath is coated on all sides of said armour; Wherein said conductor part set inside has a plurality of conductors that are coated with the fire resistant flame retardant material, and the gap between each conductor is full of filler is arranged.

Preferably, said fire resistant flame retardant material is preferably mica tape, and said fireprotection layer material is preferably the braiding glass cloth.

The utility model is through the improvement to prior art; After on the inner sheath fireprotection layer being set; Can effectively stop or prolong the influence of the intensity of a fire, especially cooperate and go up the fire resistant flame retardant material that is provided with at the conductor outer circumferential side, make that the fireproofing of cable performance is better cable; In particular surroundingss such as scenes of fire, embody the significant more effect of security performance especially.

Embodiment

As shown in Figure 1; The specific embodiment of the utility model is a kind of fire-type cable, comprises conductor part 1, insulating barrier 2, inner sheath 3, fireprotection layer 4, armour 5, oversheath 6, and said insulating barrier 2 is coated on said conductor part 1 all sides; Said inner sheath 3 is coated on said insulating barrier 2 all sides; Be coated with fireprotection layer 4 on said inner sheath 3 periphery walls, said armour 5 is coated on said fireprotection layer 4 all sides, and said oversheath 6 is coated on said armour 5 all sides; Said conductor part 1 set inside has a plurality of conductors 10 that are coated with fire resistant flame retardant material 100, and the gap between each conductor 10 is full of filler 11 is arranged.

In the present embodiment,, said fire resistant flame retardant material 100 is preferably mica tape, and said fireprotection layer 4 materials are preferably the braiding glass cloth.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The protection range that the utility model requires defines according to appended claim and equivalent thereof.
