15kV 630A / 20kV 630A IEC type Rear connector

Summary

630A IEC type Rear connector connect with IEC type tee connector or other model Rear connector,extended cable connection circuit (branch), it can not be directly connected with the sleeve socket, wall bushing and so on. The tail can be plugged directly with insulating plug, but also can be extended to connect with the rear connector of another line or Rear connector with surge arrester.
It is suitable for XLPE cable with 25mm²~400mm² cross-section of cable.

Product structure

1、Bolt stud：adopt stainless steel bolts to ensure conductor and sleeve close fit.
2、Insulating layer: special formula and mixing technology to ensure high quality of prefabricated silicone rubber
3、Internal semi conductive layer: prefabricated inner semi conductive layer to effectively control the stress of electric field.
4、Outer semi conductive layer: The prefabricated outer semi conductive layer adheres closely to the insulating layer and ensures that the outer semi conductive layer is grounded.
5、Insulating plug：Epoxy resin insulating plug with threaded metal parts to ensure close cooperation with the stud.
6、Semi-conductive end cap：seal the end of the cable connector, so that the device has a full-screen, all-sealed function.
7、Stress cone：Different size of the stress cone with the use of cable connectors, to ensure water seal and cable stress release.
8、Grounding hole: Pre-wired to the outer shield for ground wire connection.
9、Terminals: All copper or copper and aluminum crimp terminals for copper or aluminum conductor.
10、Positioning chain：Make sure the installation location is correct.

Warm Tips：

When order,please indicate the product model, voltage level, current level, the material of cable, cross-section of cable, whether with live displaying device.If users have special requirements, please indicate in the contract.
