High Voltage Earthrings are custom made for all large electrical motors rated above 400kws or 600 volts. They are 6.5mm thicker than the LV Earthrings, have 3 x more fiber, use different materials and are custom manufactured to the exact specifications of each electrical motor taking all factors into account such as the KW, Amps, Rpm, Volts, Shaft size etc.

These exact specifications are necessary due to the considerably higher shaft currents as well as higher costs of these larger motors.
