Description
Technical Field
The utility model belongs to the technical field of the transmission of electricity cable, especially, relate to a crosslinked polyethylene cable.
Background
The wire and cable for transmitting electric energy, information and converting electromagnetic energy consists of one or several insulated wire cores and their coating, protecting layer and protecting layer. And the cable among the prior art, basically all be in the cable core outside compound one deck lag can, overall structure's stability is not good enough, appears the damage along with the increase of live time easily, and under its long-time use, very easily take place to damage, the fire resistance is low, has the potential safety hazard, influences whole security performance to reduce its life-span, can not satisfy current demand. Therefore, the key point for solving the problems is to develop the insulated cable with good stability and fire resistance.
SUMMERY OF THE UTILITY MODEL
The utility model provides a crosslinked polyethylene cable.
The utility model discloses a following technical scheme realizes: including packing core, conductive core, the insulating layer of parcel on conductive core outer wall, the insulating layer is including the design layer, anti-compression layer, insulating inlayer, wear-resisting inlayer, fire-retardant layer, the outer and insulating skin of reinforceing that set gradually, set up between design layer and the anti-compression layer and reinforce the inlayer, wear-resisting inlayer, fire-retardant layer, the outer layer of reinforceing set gradually between insulating inlayer and the insulating skin.
The utility model has the advantages that: 1. the utility model has strong compression resistance, can better avoid the friction inside the cable, has high tensile strength, better guarantees the installation stability of the cable, has more stable working performance, solves the problems that the existing cable has poor stability of the whole structure, is easy to damage along with the increase of the service time and affects the whole safety performance;
2. the utility model discloses a through being provided with and strengthening inlayer and strengthening the outer layer, can be better protect the insulating cable main part of inside, avoid because the damage that uses the friction for a long time to produce to and be bitten bad by the toy, through being provided with multilayer insulation cover, can be better the insulating properties of guarantee cable, safer, overall structure's factor of safety is higher; the flame-retardant layer plays a role in realizing flame retardance and protection, and effectively improves the service quality and service life of the cable.
