By using above-mentioned technical proposal, sealing shroud further improves the waterproof of protective case in protective case is wrapped in
Sealing property.
It is preferred that, sealing shroud inwall is provided with fan-shaped raised for cooperatively forming annular ring with protective layer two.
By using above-mentioned technical proposal, fan-shaped raised and protective layer two forms annular ring with merging, and further increase is protected
Sealing at sheath opening.
The purpose of this utility model is a kind of high-tension cable with protective jacket of offer, passes through the setting increase of protective case
The rodent-proof characteristic of high-tension cable.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of high pressure with protective jacket
Cable, from-inner-to-outer is sequentially provided with interior copper conductor, conductor shield, insulating barrier one, insulation screen and insulating barrier two.
By using above-mentioned technical proposal, a kind of high-tension cable, from-inner-to-outer is sequentially provided with interior copper conductor, conductor shielding
Layer, insulating barrier one, insulation screen and insulating barrier two.The overcoat of insulating barrier two is used for the protective jacket of protection against rodents.Protective jacket is along length
Direction is opening shape, and high-tension cable can take out and in protective jacket from protective jacket.Interior copper conductor is used to be grounded, conductor
Screen layer and insulation screen are used to improve the Electric Field Distribution in high-tension cable, and insulating barrier one and insulating barrier two are mainly used for isolating
Electric wire prevents people from getting an electric shock injured.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment one
As shown in figure 1, a kind of protective jacket, from-inner-to-outer is sequentially provided with adhesive layer 1, insulating barrier 32 and protective layer 4.It is anti-
Sheath has along its length is radially provided with tooth 6 at opening 5, the opening 5 of protective jacket, the mutual dislocation of tooth 6 of the both sides of opening 5
Set, be easy to mutually embedded and fixed between tooth 6.Tooth 6 is radially started setting up at protective layer 4 since the insulating barrier 32.
Adhesive layer 1 is used for and high-tension cable is directly contacted, in order to increase fixation of the protective jacket to high-tension cable, can be viscous
Close and insulative glue is added in layer 1, the fixation that insulative glue is used between adhesive layer 1 and high-tension cable.
