Product Description
CJBK30-630-36kV 630A Dead Break Screened Separable Rear Tee Connector with Mechanical Lug (Interface C1)
CJB30-630 and CJBK30-630 are made of silicone rubber, applicable for connecting with type C1 bushing as described by CENELEC EN 50180, 50181 and DIN 47636.
The screened separable tee connector CJB30-630 is designed for connecting the polymeric cable to transformers, switchgears and other equipment.
The screened separable connector CJBK30-630 is applicable for dual cable arrangement, designed to be used with CJB30-630 screened separable tee connectors.
Features
• Rated current 630A, for max. operating voltage up to 36kV.
• The thick outer screen layer provides a total safe to touch screen which ensures safety for personnel.
• The screen break design enables cable outer sheath testing without removing or dismantling the connector.
• Electrical specification according to standard of IEC 60502-4, CENELEC HD 629.1 S2. Each separable connector is tested for AC withstand and partial discharge prior to leaving the factory.
• The overall and cut back dimensions are designed for use of minimum space required in the termination box, even double connections fit within most standard boxes.
• Suitable for both indoor and outdoor installations. Both single-core or three-core (with installed trifurcation kit) are available
