Insulated Joint Tester: Insulated Joint Slotter

May 3, 2017

ERICO (now a Pentair company) ISJ100 efficiently and safely maintains insulated rail joints to perform as required. Insulated rail joints (IRJs) are an important part of a railway signal control system. Failure of an IRJ is a significant safety issue. As such, railway infrastructure owners take extreme care in maintaining IRJs in good condition. Railhead metal flow/fatigue is one failure mode that occurs. The effect of this metal flow is contact between the two rails resulting in critical electrical isolation failure.
