Preferably, in order that cable internal structure is stable, space is by filling between the wire clamp, wire and cable core belting layer Thing is covered with.

Preferably, in order that wire clamp preferably clamps wire, clamp face face is spill hemisphere face.

Preferably, in order that cable adapts to various use environments, the oversheath and inner sheath are soft plastic product.

Preferably, in order that insulation effect is more preferable, the inner insulating layer radius is identical in conductor diameter.

Preferably, in order that wire discharges reasonably stability, the wire is arranged to three, and three wires are in equilateral Triangle-Profile.

The beneficial effects of the utility model are：Inner insulating layer is set inside wire, and external insulation layer is set on the inside of oversheath, The structure of double insulating layer can guarantee that another insulating barrier can also insulate to conductor, double insurance when a layer insulating damages It ensure that the cable moment is under insulation environment, while also increase the service life of cable；Wire clamp is provided between wire, point Every wire, wire is contacted with inner sheath closer, be also convenient for installing and extracted wire process out, and in inner insulating layer breakage The situation of short circuit can effectively be avoided；Some screen layers are set on the outside of conductor, signal interference that can be effectively between shielded conductor.
