一体式套管 200A 35kV Class Integral Loadbreak Bushing

Eaton（Cooper）一体式套管 200A 35kV Class Three Phase Integral Loadbreak Bushing (LB235B150)

Eaton meets all the requirements of IEEE Std 386™ standard, Separable Insulated Connector Systems, and combines the advantages of a reliable one-piece design with the operating features required for underground distribution switching with its Cooper Power™ series 200 A, 35 kV three-phase rated integral loadbreak bushing. The bushing is designed for pad-mounted transformers, switchgear and other apparatus filled with transformer oil, Envirotemp™ FR3™ fluid or an approved equivalent. It eliminates the insert-towell interface present in bushing well and insert primary terminations.

The three-phase rated 21.1/36.6 kV design has an ablative arc interrupter for superior arc quenching characteristics, and a fault activated piston contact assembly for a full 10 cycle, 36.6 kV fault close rating. The bushing has a continuous copper/ copper alloy current path.

The 21.1/36.6 kV three-phase rating bushing should not be used with 21.1 kV single-phase rated loadbreak elbow connectors or grounding elbows. For quick identification, 21.1/36.6 kV three-phase rated busing are color coded with purple nose pieces. Mating 21.1/36.6 kV three-phase rated loadbreak elbow connections (Catalog Section CA650068EN) have a molded purple cuff.

Single-phase rated products are color coded with tan nose pieces and molded cuffs. When mated with comparably rated products, the bushing provides a fully shielded, submersible, separable connection for loadbreak operation.
