Description

Adopt the cable core of ceramoplastic
Technical field
The utility model relates to field of cable technology, relates to a kind of cable core adopting ceramoplastic or rather.
Background technology
Cable core often adopts stranded conductor system of twisting to form, therefore need large-scale equipment carry out strand system, investment is large, costly, in addition, current cable core often adopts plastic material to wrap up, limit the application of cable under fire hazard environment, make cable inside often easily occur the phenomenon of short circuit, and then under the environment burnt, short circuit is often conducive to the expansion of the intensity of a fire, limits the application security of cable.
As can be seen here, above-mentioned existing cable heart yearn still existing defects, and urgently improved.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcomes the defect that existing cable core exists, and provides a kind of cable core adopting ceramoplastic, overcomes the defect that existing cable exists, and improves the fire resistance of cable core.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to the cable core of the employing ceramoplastic that the utility model proposes, the cross section adopting the cable core of ceramoplastic is equilateral triangle, adopt the cable core of ceramoplastic by conductive core line, puncture nail and ceramoplastic layer composition, conductive core line is wrapped up by ceramoplastic layer, conductive core line is made up of six strands of conductors, from cross section, six strands of conductors are that equilateral triangle is arranged in parallel, every three strands of conductors lay respectively at three limits of equilateral triangle, in the position of puncture nail puncture, puncture nail punctures through the three strands of conductors being positioned at position, an equilateral triangle limit along the direction on an equilateral triangle limit, in the position of three puncture nails puncture of continuous adjacent, article three, three limits of parallel equilateral triangle are successively followed closely in puncture.
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.
The cable core of employing ceramoplastic 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.
