Apparatus Bushings

PBI capacitance-graded bushings for Transformer and Oil Circuit breaker applications are a proven design based on a series capacitor core using aluminum foils and high dielectric paper impregnated with epoxy resin.

PBI CRC bushings meet all ANSI/IEEE standards for outdoor apparatus bushings as well as being demonstrated in design testing to have a far superior thermal performance.

Designed to meet the end userís needs these bushings offer lighter weight than traditional porcelain as well as having non-breakable sheds. This offers the installer less strain as well as provides a safety factor if the bushing is accidentally dropped or has something dropped on it.

Disconnect/Wall Bushings

PBI manufactures disconnect bushings for switchgear out of Capacitively graded cores for far superior performance to porcelain and Cycloaliphatic Epoxy. Our bushings are produced to have <2pC of discharge at 200% rated voltage.
