Abstract
The utility model discloses a connecting hose of a crosslinked polyethylene cable, comprising an internal semiconductive layer which is arranged outside the chip connection part of the two cables wire, and a lead tube jacket which is arranged at the utmost outside. The wire and the chip between the two cables are mutually jointed and the internal semiconductive layer is connected with an obligate segment in the screen shielding layer of the cable. Thereby, the utility model is characterized in that the outer of the internal semiconductive layer is provided with a polyethylene sulfurization insulation layer, the polyethylene sulfurization insulation layer are mutually mixed together with the polyethylene insulation of cables, the two ends of the polyethylene sulfurization insulation layer are provided with a transition connecting segment wrapping the outside layer of the cable polyethylene insulation and an outer semiconductive layer is positioned between the outside of the polyethylene sulfurization insulation layer and the outer screen shielding layer obligate segment of the cable. Thereby, with the structure, the connecting hose can reduce impurity and air gap as soon as possible and can reach the electrical properties which are similar to the properties of the crosslinked cable body with maximum pressure-proof of 35KV or so.
Description
Technical field
The utility model relates to a kind of cable joint, especially relates to a kind of connecting hose of twisted polyethylene cable.
Background technology
Existing twisted polyethylene cable often needs long length in use, and because the restriction of manufacturing technology, the length of unit cable is subjected to certain restriction.Because the length of unit cable is not enough, therefore need many cables are coupled together, and the connection of present twisted polyethylene cable usually uses connecting hose to finish.In order to guarantee that whole cable has good electric property, just require connecting hose to possess the good electric property the same with the body of twisted polyethylene cable.The structure of traditional joint is varied, and wherein result of use is preferably connecting hose, but has impurity and air gap in the insulating barrier in the structure of the connecting hose of present various structures, therefore still can't reach the desired electric property of high-tension cable.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of connecting hose of simple in structure, the twisted polyethylene cable that can reach the electric property the same with the crosslinked cable body.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of connecting hose of twisted polyethylene cable, comprise the interior semi-conductive layer outside the core connecting portion that is arranged on two cables and be arranged on outmost lead pipe sheath, be welded to each other between the core of two cables, semi-conductive layer combines with cable internal shield reservation section in described, semi-conductive layer is outside equipped with polyethylene filling and vulcanization insulating barrier in described, the polyethylene layer of described polyethylene filling and vulcanization insulating barrier and cable vulcanizes fusion mutually, described polyethylene filling and vulcanization insulating barrier two ends are provided with the outer transition linkage section of polyethylene layer that is coated on cable, and described polyethylene filling and vulcanization insulating barrier is outside equipped with the outer shielding layer of cable and reserves the outer semiconducting layer that section combines.
Described polyethylene filling and vulcanization insulating barrier is formed by polyethylene material filling and vulcanization.
The outer surface of the two ends of described lead pipe sheath and the plumbous pillar of cable is welded to each other.
Compared with prior art, advantage of the present utility model is to be provided with polyethylene filling and vulcanization insulating barrier outside interior semi-conductive layer, the polyethylene layer of polyethylene filling and vulcanization insulating barrier and cable vulcanizes fusion mutually, make the structure of cable flexible joint reduce the existence of impurity and air gap as much as possible, the connecting hose of this structure also can reach the electric property that is close with the crosslinked cable body, the highest withstand voltage reaching about 35Kv preferably.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
