The PSRB surge arrester is available for applications up to 220kV systems.

The design utilises a housing construction, which is a resin and glass fibre strengthening sleeve over moulded with Silicone Rubber outer insulating housing fitted with aluminium flanges.

High cantilever mechanical strength is achieved on this design with the internal assembly similar to that of the porcelain Housed Surge Arrester.

The design has been tested to IEC and demonstrates a 63kA short circuit performance.

Routine tests are carried out to show that the manufacturing conforms to the current international standard.
