Third Rail Insulators
A third rail is a method of providing electric power to the railway train. It is a continuous conductor placed along the railway track. A third rail insulator is the insulation supporter that holds the third rail at internals of about 3 meters. Sheet molding compound (SMC) material is the best choice for this application.
SMC is a self-insulated material that can prevent electric from leaking to the ground. It is very strong and weather resistant so it can provide the third rail with high mechanical supporting strength for over 30 years. Each insulator withstands over 20 tons of compression loading. No maintenance except cleaning is needed. The third rail sometimes creates electric arc that lights up the oily dust along the railway track. This could be very dangerous. But SMC material is fire resistant. Without continuous burning source, SMC material extinguishes within seconds. High strength, insulation, fire resistance and long serving life, these exceptional properties provide the best third rail supporting solution.
