PBI - Piedmont Bushings and Insulators
Bushings - Entrance, Apparatus, Disconnect / Wall, Repairs
Capacitance-Graded Oil Free Bushings with silicone sheds rated from 15Kv through 69Kv 110 through 350 BIL and through 4000 amperes for Outdoor to Indoor applications. These bushings are suitable for vacuum circuit breakers, switchgear, and Current Transformers.
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 user’s 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.
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.
