25Kv Mk 3 Railway Insulator

Moulded onto high strength GRP rods, these insulators utilise Henley's unique EPDM dielectric cladding material. This highly successful cladding has been proven around the world from deserts to arctic environments for more than 30 years. The material has outstanding pollution and weathering performance which, coupled with its nonflammability, also makes it ideal for tunnels and stations where natural rain-washing is not possible.

Moulded onto high strength GRP rods, our range of insulators utilise WT Henley's unique EPDM cladding. This highly successful material has been well proven right around the World from desert conditions of Africa to the iced expanses of Canada and has also been used by many Electricity utilities for 40 years.Innovative self cleaning designSome of the harshest environments we have encountered are those on the Ayrshire coast in Scotland. At this particular location, the 25kV electrified railway catenary network, runs parallel with the coast for some 20 miles. As a result the system is continually subjected to an aggressive sea-salt environment. At its worst the sea waves crash over the catenary itself. To help overcome such problems under these conditions when using traditional ceramic insulator technology, washing, replacement and/or an increased number of units are required. In using WT Henley's Polymeric technology, the open profile design and self cleaning nature of our insulators, ensures greatly improved system reliability.
