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 outer conductors is made up of conductive copper wire system of twisting.
Better, the thickness of above-mentioned glue layer is 0.5 millimeter to 2 millimeters.
The cable of fire-type new structure 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 ten thigh lateral conductors and sub-thread middle conductor composition arranged in parallel instead of strand to make, 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, the L-shaped filling rate that effectively can improve conductor of middle conductor cross section.Glue layer parcel cable core, avoid extrusion procedure, reduce investment in fixed assets, glass steel band can play the effect of armouring, and protection cable is not by the injury of blunt, and when burning, glass steel band can prevent the short circuit in fire from occurring effectively.
