Bushing Extender R-800

15 and 25kV Bushing Extender R-800
The Richards Bushing Extender R-800 is the only fully integrated 200A Loadbreak Tap and 600/900A Deadbreak Bushing Extender. Like many Richards Medium Voltage innovations, this product takes multiple components and combines them into a single factory molded and tested unit. This not only reduces installation cost and effort, but increases reliability and quality for our customers. The Bushing Extender R-800 is used to transition from an IEEE 386 600/900A Deadbreak interface to an IEEE 386 200A Loadbreak interface. Typical applications include:
  • Installation of a 200A Loadbreak Elbow
  • Installation of a 200A Surge Arrester
  • Installation of an Insulating Cap, removed when testing the interface using approved voltage-indicators
IEEE 386 – Industry Minimum Requirements
