Porcelain transformer bushing insulator features:
  • One-piece solid cast insulation (no-oil)
  • Installation possible at any angle
  • Superior performance in earthquake zones compared to porcelain - very resistant to vibration Insensitive to moisture
  • Resistant to salt fog
  • Not affected by temperature variations
  • Less parts per bushing; simpler construction

Connector can be designed for brazed or crimped configuration. Available in 400A draw-lead or 400/1200A interchangeable with bottom connect terminal. Bushing can be used with or without a bottom terminal.

Machined high strength aluminum with a leak-proof seal between the bushing and the equipment, the test tap is integrated into the mounting flange, capacitance taps come standard with transformer bushings, optional for breaker bushings.

Porcelain transformer bushing insulator, ground shield connection is provided by a solid welded pin attachment.
