15kV / 20kV 630A Insulation Protection Cap Sparable Connectors

15kV 630A insulation protection cap is an accessory of live bushing. It is reserved to provide insulation and seal protection for live bushing lines, and provides dustproof, moisture-proof and seal protection for non-live interface. It is suitable for the inlet and outlet terminals of ring network switchgear (crosslinked power cable). It is suitable for C type casing in EN50180-50181, such as inlet and outlet bushing seat of switch cabinet, wall bushing of cable branch line and double pass bushing.

OEM production is accepted

This is plug type accessories,also named Separable Connectors.It includes separable Elbow,straight and Tee connector kits.Our separable connectors are widely used in switchgears,transformers,cabinets and other electrical equipments.It is made of EPDM or silicone rubber with integrated field control.And adopts advanced triple-layer( a conductive inner layer,an insulation layer and a conductive outer layer) injection technique to guarantee the interface property to avoid gaps between layers and decrease partial discharge maximally.Our separable connectors are mainly includes IEC type & IEEE type.

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.
