Description

CJB20-1250-24kV 1250A Dead Break Screened Separable Front Tee Connector (Interface C2)
 


Interface C2 bushing (1250A)
CJB20-1250 and CJBK20-1250 are made of silicone rubber, suit for connecting with type C2 bushing as described by CENELEC EN 50180, 50181 and DIN 47636.
CJB20-1250
The screened separable tee connector CJB20-1250 is designed to connect the polymeric cable to transformers, switch gears and other equipment.
CJBK20-1250
The screened separable connector CJBK20-1250 is application for dual cable arrangement, designed to be used with CJB20-1250 screened separable tee connectors.

 
Features

• Rated current 1250A, for max. operating voltage up to 24kV.
• 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
