Abstract

The utility model belongs to a cable joint, which is composed of the parts of a cable joint, a ground point, a test point, a wire pressing point, a semi-conductive shielding layer, a semi-conductive layer, a high-quality insulating layer, etc., wherein, the cable joint and a wire pressing head are arranged in the semi-conductive layer; the high-quality insulating layer is arranged out of the semi-conductive layer; the semi-conductive shielding layer is arranged out of the high-quality insulating layer, and the ground point and the test point are arranged on the high-quality insulating layer. The utility model has simple connected and combined mode, convenience, safety, reasonable design and novel manufacture.

Description

High-voltage cable joint

The utility model belongs to cable joint.

The switching of the present cable of China is that the underground cable switching is aerial, and branch supplies with electricity consumer, and then it is underground that leader cable is transferred, and its weak point is that engineering is big, the cost height; Poor stability.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of simple and convenient, the safe and reliable high-voltage cable joint that provides.

The purpose of this utility model can reach by following measure: at first making the cable nexine is semi-conductive layer, in this layer, cable joint and line ball head are set, cable joint can not connect the tele-release arc in this layer, in semi-conductive layer arranged outside intermediate layer is high-quality insulating barrier, at insulating barrier arranged outside skin is semiconductive shielding layer, this the layer on and be provided with earth point, electric charge is discharged over the ground, also be provided with test point.

The utility model has following advantage compared to existing technology:

1, this design can be connected to all finger assignments systems underground;

2, the connection compound mode is simple, convenient, flexible, various;

3, all insulation, full sealed non-maintenance are corrosion-resistant, safe and reliable;

4, also applicable to any adverse circumstances (as snowstorm, flood, high pollution district) on ground;

5, saving equipment and cable investment improves power supply reliability, is widely used in commercial center's Industry Development Area and urban population compact district.

The accompanying drawing drawing is described as follows:

Fig. 1 is the utility model elbow type junction composition

Fig. 2 is the utility model T connector structure chart

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

Embodiment one is with reference to accompanying drawing 1, the utility model elbow type joint is by cable connector 1, earth point 2, test point 3, crimp head 4, handle hole 5, semiconductive shielding layer 6, conducting rod 7, snap ring 8, semi-conductive layer 9, sign cup 10, high-quality insulating barrier 11, all press 12 to form, 9 li cable joint 1 is set at semiconductive layer, and establish crimp head 4, can ground connection not put arc in this layer, at semi-conductive layer 9 skins high-quality insulating barrier 11 is set, at insulating barrier 11 skins semiconductive shielding layer 6 is set, by earth point 2 charge inducing is discharged over the ground, this layer be setting operation hole 5 and test point 3 simultaneously, handled easily and outage test.

Embodiment two, with reference to accompanying drawing 2, the utility model T connector is by cable joint 13, high-quality insulating barrier 14, crimp head 15, semiconductive shielding layer 16, bolt 17, head protector 18, insulating plug 19, semi-conductive layer 20, test point 21, earth point 22 is formed, 20 li of semi-conductive layers cable joint 13 and crimp head 15 are set, this layer can not connect arc discharge, high-quality insulating barrier 19 is set outside semi-conductive layer 20, semiconductive shielding layer 16 is set outside insulating barrier, by earth point 22 electric charge is discharged over the ground, T type cable joint two can connect elbow type cable joint, also can take over control helmet 18, charged and fault detector etc.
