15kV 630A / 15kV 630A lnsulated cap

OEM and ODM are accepted

Summary
630A insulated cap is an accessories of live bushing, which provides insulating cover protection for the live bushing, and provides a dust-proof and moisture-proof protection for the nonelectrified connector.
630A insulated cap can be installed on the 630A bushing and busbar or other equipments, when the cable wiring reserved backup connectors, it must be sealed with a 630A insulated cap.
630A insulated cap made of high quality silicone rubber, fully insulated, fully sealed, safe and reliable.

Type description

Product structure
1、Insulating layer: special formula and mixing technology to ensure high quality of prefabricated silicone rubber.
2、Internal semi conductive layer: prefabricated inner semi conductive layer to effectively control the stress of electric field.
3、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.
4. Operating ring: made of stainless steel and more easy for installation and operation.
5. With the thread: thread size metric coarse thread M16.
6、Grounding hole: Pre-wired to the outer shield for ground wire connection.
