Machine per-compound class crosslinking agent or silane crosslinker.
Further technical solution is that crosslinking agent is DCP or methyl triacetoxysilane.Color masterbatch uses darkness board electric wire
Cable black masterbatch or gold shake board BK2014B black agglomerates.DCP, that is, cumyl peroxide.
Further technical solution is, PE sheaths further include the heat-resisting sleeve being set in outside jacket body, among heat-resisting sleeve
Equipped with flowing coating of cooling liquid, the material of heat-resisting sleeve is PET, Teflon or EVA.PET, that is, polyethylene terephthalate；EVA is
Ethylene-vinyl acetate copolymer；It can so be held at work to avoid the conducting wire in the jacket body or jacket body in heat-resisting sleeve
Deformed by high temperature.
Further technical solution is the closing housing that flowing coating of cooling liquid is set for heat-resisting sleeve middle part.So cable works
Coolant is injected in housing by preceding elder generation, then works again in line attachment, can so be born when cable works high temperature without
Deformation expansion, plus material itself by being modified so that this ability is greatly improved.
Further technical solution is that flowing coating of cooling liquid is the housing set in the middle part of heat-resisting sleeve, and housing both ends are set respectively
Inlet and liquid outlet.Can so carry out the circulation of coolant when cable works, extend cable bear hot operation when
It is long.
