15kV/ 20kV 200A/600A Insulation Protection Cap

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.
