Bowthorpe Polymeric Surge Arresters (PSRB Range)
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.
