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 Henleys 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). nnҕProduct approvalPA05/534 Network Rail standardRT/E/S/21082ՕDirect replacement forporcelain insulators for
