Product Description

CJB30-1250 CJBK30-1250-36kV 1250A Dead Break Screened Separable Tee Connector (Interface C2)
 

Interface C2 bushing (1250A)
CJB30-1250 and CJBK30-1250 are made of silicone rubber, suit for connecting with type C1 bushing as described by CENELEC EN 50180, 50181 and DIN 47636.
CJB30-1250
The screened separable tee connector CJB30-1250 is designed to connect the polymeric cable to transformers, switchgears and other equipments.
CJBK30-1250
The screened separable connector CJBK30-1250 is application for dual cable arrangement, designed to be used with CJB30-1250 screened separable tee connectors.
 

Design 
• Type C2 bushing
• Stud + nut + washers
• Insulating back plug
• Cable lug
• Inner screen layer
• Insulation layer
• Outer screen layer
• Stress cone
• Earthing wire
• Cable core
• B type connecting rod
 

Features
• Rated current 1250A, 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.
