Type description

 

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.
