Preferably, the first protective sleeve and the second protective sleeve are both made of polyvinyl fluoride materials, the thickness of the first protective sleeve and the thickness of the second protective sleeve are not more than 1 mm, the first protective sleeve and the second protective sleeve have the effects of insulation and high temperature resistance, and the situation that the protective sleeves are softened and cracked due to continuous work of the wire cores is avoided.

Preferably, the elastic layer is made of a polyurethane material and has a thickness of 0.3 mm to 0.5 mm, so that the overall circuit has good elasticity and an elastic effect is increased.

Preferably, the waterproof layer is made of polypropylene materials, and the thickness is between 0.1 millimeter and 0.25 millimeter, so that the condition that water seepage occurs due to the fact that the waterproof layer is soaked by rainwater is avoided.

Preferably, the wearing layer is made by polyvinyl chloride material, and thickness is no longer than 0.8 millimeter, can have sufficient intensity, can not lead to the cortex ftractureing when wearing and tearing or scraping, avoids the mouse to bite and the condition that the cable leaked electricity appears.

Preferably, the support bar is made by elasticity polyester plastic material, can support the reality to four sinle silks of inside and support, after winding hot working, avoids sinle silk offset, influences the stability that flexible resets.

Preferably, the fireproof filling layer is made of fireproof glue material, and the powder ground by the flame retardant particles is doped in the glue, so that the internal flame retardant effect can be further improved.

Compared with the prior art, the beneficial effects of the utility model are that: can guarantee the elasticity of whole helix through the elastic layer, cooperate a plurality of flame retardant coatings again, can improve the fire resistance of whole helix, simultaneously, the wearing layer can improve the stand wear and tear intensity of helix, improves the barrier propterty of whole cable greatly, avoids the mouse to bite and receive the damage, increase application scope.
