25kV AC Railway Insulators

Mark 3 Polymeric Insulators - 14025 Mark 3 Polymeric Insulators

This range of polymeric insulators isdesigned to directly replace ceramic insulators used for Mark 3A, 3B and 3C equipment. Separate designs covereither Tension or Cantilever applicationsensuring full compliance to the latest Network Rail mechanical load specifications(Factor of Safety: 4).Moulded onto high strength GRP rods,these insulators utilise Henley’s uniqueEPDM dielectric cladding material. This highly successful cladding has been proven around the world from desertsto arctic environments for more than30 years. The material has outstanding pollution and weathering performancewhich, coupled with its non-flammability, also makes it ideal fortunnels and stations where natural rain-washing is not possible.W.T. Henley insulators are light andlow profile. Manufactured with Malleable Iron end-fittings, (aluminium end-fittings can be supplied on request).
