25kV AC Railway Insulators

This vandal resistant insulator is
designed specifically to directly replace
two ceramic cap and pin insulators to
drawing 121/003/002 and 121/833/001
for use only in horizontal, in-line
configurations.This insulator can also be used toreplace one cap and pin insulatorwhere coupling length can be exceededMoulded on to high strength GRP rods,these insulators utilise Henleys uniqueEPDM dielectric cladding. This highly
successful cladding has been proven
around the world from deserts to arctic
environments for more than 30 years.
The material has outstanding pollutionand weathering performance which,coupled with its non-flammability, also
makes it ideal for tunnels and stationswhere natural rain-washing is not
possible.These insulators have 16mm spungalvanised (to BS EN ISO 1461), cast SG
iron ball and socket end-fittings (to
BS3288 and IEC publication 120). They
are supplied with phosphor bronzesecurity clips to IEC publication 372.This insulator is also available withtongue and clevis end fittings to
IEC471.The weight of this unit, which isapprox.1.6kgs contrasts with the
porcelain equivalent at 11kgs, (for two
porcelain discs) which makes handlingand installation much easier. ҕ >
