Better, above-mentioned puncture nail circular in cross-section, the fluted ring in surface of puncture nail.

Better, in the position of three puncture nails puncture of continuous adjacent, the spacing distance of above-mentioned puncture nail is 1.5 times of the square root numerical value of conductive core line cross-sectional area to 3 times.

Better, the A/F of above-mentioned groove ring is 0.05 times of the square root numerical value of conductive core line cross-sectional area to 0.09 times.

Better, the axis direction that the direction that above-mentioned puncture nail punctures extends perpendicular to conductor.

Better, above-mentioned puncture nail has sharp-pointed most advanced and sophisticated position.

Better, above-mentioned conductor is made up of conductive copper wire system of twisting.

Better, the longitudinal length of above-mentioned fiberglass locating sleeve is 20 times of the square root numerical value of conductive core line cross-sectional area to 100 times.

The cable of the new structure of employing ceramoplastic insulation described in the utility model, its beneficial effect produced is: ceramoplastic is a kind of high temperature resistant baked wheaten cake and has good flexible new material, ceramoplastic is adopted to carry out conductive core line wrapping up the destruction that effectively can completely cut off and burn conductive core line, conductive core line adopts conductor composition arranged in parallel instead of strand system, this reduces the cost that strand operation processed is brought, it also avoid strand simultaneously and make the internal stress brought to conductive core line, the conductor burning Fracture is avoided to destroy outer field ceramoplastic owing to twisting the release of stress processed, with the fixing each stock conductor of puncture nail, the movement of conductor at horizontal direction can be retrained, conductor can be given again in longitudinally certain degree of freedom, so just can avoid the concentrated release at cable bend position stress, also conductor can be reduced to ceramoplastic stress, evade the defect of ceramoplastic be full of cracks, locating sleeve is fixed and is separated two strands of cable cores, short circuit after heart yearn can be avoided in baked wheaten cake to touch, and eliminates the processing procedure of extrusion molding simultaneously, reduce cost, and can adapt to the requirement of customization more easily in cable molding process.Fire barrier and fiberglass locating sleeve can retrain cable core well, and cable is easily laid, and in baked wheaten cake, avoid stress to cause the short circuit of wire.
