ABSTRACT:
An electrical connector assembly for use with a nuclear power plant pressurizer heater includes an external metal shell having a base end and a connection end with a header located internally of the shell intermediate the two ends. Connector pins extend from end to end of the shell passing through apertures in the header. About the pins there is placed a high voltage insulator such as a ceramic material extending on either side of the header. The base end of the connector is filled with an insulative reinforcement material completely surrounding the pins. The connection end is filled with a granular thermally stable insulative material and closed by connection to a heater assembly. The base end of the connector may also include an external flexible covering of insulative material to further protect the pins and reinforcement material from hydroscopic contamination.
