25kV AC Railway Insulators

Return Conductor Support Clamp Insulator - 14025 Return Conductor SupportClamp Insulator

This vandal resistant insulator is designed for direct replacement of traditional porcelain insulators (Network Rail Part number 121/42/1).Moulded onto high strength GRP rods,these insulators utilise Henley’s unique EPDM dielectric cladding. This highlysuccessful cladding has been provenaround 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 stations where natural rain-washing is not possible.End fittings are cast malleable iron,spun galvanised to BS EN ISO 1461. With the appropriate aluminium liner,the clamp will accept aluminium return wires from 16.5mm to 21mm diameter. (19/3.25 and 19/4.22 conductors).(Tinned copper liners for copper cablesavailable on request)The clamp will retain the conductorwithout slippage at more than 400kgcable load.The insulator can be supplied with achoice of stainless steel mounting configurations: a socket-countersunkscrew for flush mounted brackets orahexagon bolt for direct mast mounting.
