Abstract

The utility model discloses a fireproof cable, and the cable comprises at least a cable core, a filling layer wrapping the cable core, a cable wind-cladding layer wrapping the filling layer, and a sheath layer wrapping the cable wind-cladding layer; wherein the cable core comprises a conductor, a cable core wind-cladding layer wrapping the conductor, and an insulating layer wrapping the cable core wind-cladding layer; and both the cable core wind-cladding layer and the cable wind-cladding layer are prepared through wind-cladding mica tape, and both the insulating layer and the sheath layer are prepared by ceramic silicon rubber material. The fireproof cable provided by the utility model is themostable, can effectively guarantee the cable to normally work under flame or high temperature condition, can reduce generation of toxic gas in combustion, and minimize damage to human body.

Description

Fire-resisting cable

Technical field

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

Background technology

Common cable is under fire condition, and insulation and sheath burning at once become ash, makes cable produce short circuit and helps burning, and burning produces a large amount of flue dust and toxic gases and can cause serious injury to human body.

The utility model content

The technical problem that the utility model will solve is: overcome the deficiency in the prior art, provide a kind of high temperature resistant, but guarantee that effectively cable operate as normal under flame or hot conditions also can reduce the fire-resisting cable of the generation of toxic gas when burning.

The utility model solves the technical scheme that its technical problem adopted: a kind of fire-resisting cable; Comprise the packed layer of at least one cable core, parcel cable core, the cable lapping layer of parcel packed layer and the restrictive coating of parcel cable lapping layer; Cable core comprises the core wrap of conductor, parcel conductor and the insulating barrier of parcel core wrap; Core wrap and cable lapping layer are processed by mica tape is wrapped, and insulating barrier and restrictive coating are processed by the pottery silastic material.

Core wrap is an individual layer or double-deck.Cable core is five.

The beneficial effect of the utility model is: the fire-resisting cable that the utility model provides can be high temperature resistant, but effectively guarantee cable operate as normal under flame or hot conditions, and can reduce the generation of toxic gas when burning, and reduces the injury that human body is caused.

Embodiment

Combine accompanying drawing that the utility model is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.

A kind of fire-resisting cable as depicted in figs. 1 and 2; Comprise the packed layer 1 of five cable cores, parcel cable core, the cable lapping layer 2 of parcel packed layer 1 and the restrictive coating 3 of parcel cable lapping layer 2, cable core comprises the core wrap 5 of conductor 4, parcel conductor 4 and the insulating barrier 6 of parcel core wrap 5.

The fire-resisting cable that the utility model provides adopts the composite construction fire prevention.Core wrap 5 uses individual layers with cable lapping layer 2 or double-deck mica tape is wrapped processes, and has reduced conductor 4 and cable core cause expansion because of being heated under combustion case power, and insulating barrier 6 and restrictive coating 3 are exerted an influence.Insulating barrier 6 adopts the potteryization silastic material to process with restrictive coating 3, under hot conditions, can form hard pottery housing internal layer is protected, and prevents that mica tape receives thermal spalling.Not meeting under the situation of fire, can guarantee that cable has good bending property.Under the situation of meeting fire or high temperature, potteryization silicon rubber can become the ceramic body of tubulose, has good insulation performance performance and effect of heat insulation, guarantees that effectively cable can operate as normal under flame or hot conditions, is not affected by the external environment.At 950 ℃ and follow that burning still can guarantee the cable operate as normal in 180 minutes under the situation of spray.And the material low smoke and zero halogen of the utility model greatly reduces the generation of pernicious gas under the fire condition, reduces the injury to human body.

Above-mentioned execution mode is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection range of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection range of the utility model.
