Preferably, the conductor wire core includes several groups copper conductor, and every group of copper conductor is twisted by 5-15 root copper wire, The diameter of the copper wire is 2-8mm.

Preferably, the wrapping layer is 1-3 layers.

Preferably, the filled layer is magnesia minerals filled layer.

Preferably, the copper sheath with a thickness of 2-5mm.

Preferably, the oversheath is low smoke, zero halogen oversheath.

Compared with prior art, the utility model has the beneficial effects that the utility model includes several by conductor wire core Group copper conductor, every group of copper conductor are twisted by 5-15 root copper wire, so that conductor wire core has good tensile property；

By the setting of wrapping layer, the insulation effect of cable is enhanced；

It is the setting of magnesia minerals filled layer by filled layer, there is fire prevention, fire resisting, high temperature resistant, thermal insulation and heat-insulated The advantages of；

By the setting of flame resistant filler rope and flame retardant coating, there is flame retardant property, improve the safety in utilization of cable；

By the setting of water blocking tape layer, good resistance effect is played, improves the safe application performance of cable；

It is the setting of low smoke, zero halogen oversheath by oversheath, improves the high temperature resistant of cable, flame retardant property, and improve Service life.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model；
