Description

Green fire prevention safety wire

Technical field

The utility model relates to a kind of green fire prevention safety cables, and applied to dress, family is used, and is had more safe and environment-friendly Feature.

Background technique

With the development of society and the improvement of people's living standards, environmentally protective house decoration and energy conservation are increasingly advocated The household electrical appliance of safety.The electric wire of house ornamentation electric wire and household electrical appliance is increasingly diversified, and the range of application is also more and more extensive.Secretly The electric wire that dress is laid needs to consider insulation safety type and service life, and fire-protection rating requires height, and electric appliance line when in use, often needs It is moved, will receive distortion, winding unavoidably in the process of moving, regular distortion, winding are easy to be broken off, this will Situations such as will cause unstable electric current, resistance increase, more serious problem are the accidents that can be generated short-circuit or electric wire and catch fire.Meanwhile Electric wire in transportational process or other use environments, caused by local dielectric damage, fall off without check immediately come, It is easy initiation accident in use, while needing labor intensive in the detection process, increases cost of labor.Currently, existing Its structure of house ornamentation electric wire mainly includes copper core, is coated with one layer or two layer insulatings in copper core, the electric wire of this spline structure, though It so can satisfy the demand of general home-use electric wire, still, there are still such as in family's use process for the electric wire of this spline structure Under deficiency: due to only having one layer or two layer insulatings, and the thickness of insulating layer itself is relatively thin, installs to electric wire When, it is easy to damage insulating layer, leads to the generation of leaky, once damage, will be unable to guarantee safety；Due to electric wire The mechanical performance of itself is lower, and temperature resistant grade is low, can only adapt to 70 DEG C of highest of temperature；Insulating layer itself is to be made of plastics, Predominantly pvc material, melting point is low, once it is short-circuit, it is easy to happen fire, poisonous smog, PVC material will have been released Expect that the service life is lower, generally 20-30, the aging heel project amount that rewires is big, at high cost.

Utility model content

In view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of structure is simple, environmentally protective, safety uses the utility model The green fire prevention safety wire of service life length.

The technical solution adopted in the utility model is thus: green fire prevention safety wire, including by sub-thread or multifilament Conductor strand at cable core conductor (1), several cable core conductor (1) the outer cladding inner layer mineral insulation bands (2), the inner layer Mineral insulation band (2) outer cladding outer layer calcines mica insulation band (3), extrudes and can hand over outside outer layer calcining mica insulation band (3) Connection type high-temperature resistant low-fume non-bittern environmental protection insulating layer (4).

The inner layer mineral insulation band (2) with a thickness of 0.14-0.20mm.

Outer layer calcining mica insulation band (3) with a thickness of 0.17-0.20mm.

Cross-linkable high-temperature resistant low-fume non-bittern environmental protection insulating layer (4) the heatproof temperature reaches 150 DEG C.

The utility model has the advantages that: cable core conductor is twisted by only stock or the high-quality copper wire of multifilament, improves electricity The pliability of line, entirety degree；Inner layer mineral insulation band and outer layer calcining mica insulation band ensure the continuity of mica insulation layer And reliability, the calcining disconnection of mica insulation band caused by the bending disturbance in cable wiring manufacture and imperfect is prevented, is improved Electric wire refractory temperature and fire-protection rating；Select low smoke and zero halogen performance it is excellent without the halogens such as chlorine, bromine, without the weight such as lead, chromium, mercury The insulation of metal, guarantees the environmental requirement for realizing low smoke and zero halogen, and electric wire will not be released in flame condition to human body respiration Organ has the gas and dense smoke of intense stimulus；Using high flame retardant insulating materials and compact structure design, gapless knot Structure significantly reduces air to the negative effect of flame retardant property, the nonmetallic materials such as wrapped and sheath of high flame retardant, it is ensured that The excellent flame retardant property of the utility model.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

1 is cable core conductor in figure；2 be inner layer mineral insulation band；3 calcine mica insulation band for outer layer；4 is resistance to for Cross-linkable High temperature low-smoke non-halogen flame-retardant environmental protection insulating layer.

Specific embodiment

Green fire prevention safety wire, including by sub-thread or multifilament conductor strand at cable core conductor 1, described in several 1 outer cladding inner layer mineral insulation band 2 of cable core conductor, the 2 outer cladding outer layer of inner layer mineral insulation band calcine mica insulation band 3, Cross-linkable high-temperature resistant low-fume non-bittern environmental protection insulating layer 4 is extruded outside the outer layer calcining mica insulation band 3.

The inner layer mineral insulation band 2 with a thickness of 0.14-0.20mm.

Outer layer calcining mica insulation band 3 with a thickness of 0.17-0.20mm.

The 4 heatproof temperature of Cross-linkable high-temperature resistant low-fume non-bittern environmental protection insulating layer reaches 150 DEG C.

Further make following explanation: environmentally protective safety wire, by sub-thread or multifilament conductor strand at one Cable core conductor 1 coats one layer of inner layer mineral insulation band 2, with a thickness of 0.14-0.20mm, in inner layer mine outside cable core conductor 1 One layer of outer layer of cladding calcines mica insulation band 3 to 2 outside of object insulating tape again, exhausted in outer layer calcining mica with a thickness of 0.17-0.20mm The outside of marginal zone 3 extrudes Cross-linkable high-temperature resistant low-fume non-bittern environmental protection insulating layer 4.

As the further improvement of the utility model, the insulating layer is Cross-linkable high-temperature resistant low-fume non-bittern ring Protect material.The material heatproof can reach 150 DEG C, and service life was ranged up to up to 70 years.
