Core features

  • Quality OEM bushings and bushing wells for single- and three-phase distribution transformers
  • Removable stud bushing well provisions for easy removal of broken parts from both the bushing well and insert
  • 200 kV BIL bushings available for 35 kV applications
  • 900 amp copper bushing options
  • Series multiple switches offer easy reconnect of transformer windings from series to parallel with a simple turn of the switch on a de-energized transformer
  • Tap changer switches offer externally operable switching to regulate voltage as lines grow
  • Sectionalizing loadbreak switches offer transfer of apparatus from one source to another without loss of service continuity

Features reliable, one-piece construction

The 200 A 35 kV three-phase rated integral loadbreak bushing 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.

Replace multiple switches with sectionalizing loadbreak switch

Eaton's Cooper Power series four-position sectionalizing loadbreak switch improves system reliability with make-before-break switching operations and may replace multiple two position loadbreak switches for a simplified design and operational procedures.

Externally operable switching for ease of use

Tap changer switches offer externally operable switching to regulate voltage as lines grow. Sectionalizing loadbreak switches offer transfer of apparatus from one source to another without loss of service continuity.
