The requirement of the quality and function of cable is also higher and higher；The halogen material of common cable generally use such as PVC insulating layers are as shield
Jacket layer, structure is not close, it is crucial that once occur fire PVC insulated wire cable fire can generate it is a large amount of dense
Cigarette so that rescue personnel and the disaster-stricken common people are often bottled up even death by suffocation by smog, are difficult to rescue work, rescue effect
Rate is low, meanwhile, the burning of halogen material can generate a large amount of toxic gas again and pollute air；In addition, current cable feature
On it is single be also required to change, cable laying is compact due to internal combination, it is difficult to carry out angle and curved, therefore produce one kind
Cable that is rational in infrastructure and can overcoming disadvantages mentioned above seems very urgent, so providing a kind of LSOH anti-flaming for fire-fighting
Electric wire come solve the above-mentioned problem very it is necessary to.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of halogen-free low-smoke flame-retardant electric wire and cable for fire-fighting
The problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical solution：A kind of LSOH anti-flaming for fire-fighting
Electric wire including cushion block, is provided with groove on the outside of the cushion block, the inside grooves are equipped with stranded conductor, the stranded conductor
Include copper core, internal shield is equipped on the outside of the copper core, external shielding layer, the internal shield are equipped on the outside of the internal shield
Between external shielding layer cable core belting layer, the cable core belting layer are equipped with filled with the second filled layer, the stranded conductor outside
Outside is cased with inner sheath, is cased with oversheath on the outside of the inner sheath, is filled out between the cushion block and cable core belting layer filled with first
Fill layer.
Preferably, the groove is arc-shaped structure.
Preferably, the quantity of the groove is identical with the quantity of stranded conductor, and the groove center is symmetrical.
Preferably, the inner sheath is low smoke, zero halogen irradiation cross-linking flame-retardant polyolefin sheath layer.
Preferably, the cushion block is internally provided with cavity, and the cavity is circular configuration.
Preferably, the oversheath is epoxy resin adhesive film.
Compared with prior art, the beneficial effects of the utility model are：A kind of Halogen for fire-fighting of the utility model is low
Smoke flame-retardant electric wire and cable, structure novel, energy high temperature resistant can not also generate pungent smog, and compared to pervious after burning
Cable has better bending performance, saves installing and using for cable.It is twisted by the setting of groove and cushion block upper plenum
Conducting wire is easier to be bent along the camber line of inside grooves, increases the bending angle of cable, reduces the wave that cable is installed and used
Take, saved the cost installed and used.The oversheath of epoxy resin adhesive film has good heat safe effect, is exactly integrally
It is ignited there will not be a large amount of pungent smog, escape convenient for building internal staff.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of LSOH anti-flaming electric wire for fire-fighting
Cable, including cushion block 1,1 outside of cushion block is provided with groove 2, and the groove 2 is internally provided with stranded conductor 3, the stranded conductor
3 include copper core 8, and 8 outside of copper core is equipped with internal shield 9, and 9 outside of internal shield is equipped with external shielding layer 11, described
Cable core belting layer 5 is equipped with filled with the second filled layer 10,3 outside of stranded conductor between internal shield 9 and external shielding layer 11,
5 outside of cable core belting layer is cased with inner sheath 6, and 6 outside of inner sheath is cased with oversheath 7, the cushion block 1 and cable core band
