ABSTRACT:
Overvoltage protector unit for use in a well in which an overvoltage protection device is mounted in a grounding housing and electrically separates a conductor pin in the housing from the housing during normal voltage conditions. The conductor pin is mounted within a flame resistant resilient elastomeric dielectric support which also electrically isolates it from the housing. The support cushions the pin before installation of the unit and the unit is unlikely to suffer damage during storage or transit upon the protection device failing, the resilient support flexes to enable line to ground contact to be established.
