Spark Gap & Non Linear Resistor Cubicles

2000A/4000A/6000A/8000A or 9000A rms for 0.2s

Where there is 25kV overhead lines and 750V DC, the non-linear resistors provide a path back to source for currents flowing in short circuits of the 25kV AC overhead lines, while limiting the current which flows during the normal operation of the railway.

The spark gap device triggers to limit earth voltage to a safe level. The resistors limit the running rail touch voltage to within safe levels. This restricts the risk of stray DC currents.

Note some units have been supplied without the spark gap device where the detection has been provided externally to the resistor panel.
