ABSTRACT:
Apparatus for energizing submergible pumping equipment in an underwater well comprises a suspension head for the equipment and an adapter spool associated with wellhead apparatus and in which the suspension head seats. The apparatus includes internal electrical contacts within the adapter spool and contacts carried by radially expandable slips on the suspension head for establishing electrical connection between an external power source and the supply cable for the equipment which is carried by the suspension head. When the head is seated in the spool, radially expanding movement of the slips brings the respective contacts into engagement. The apparatus further includes complementary alignment formations on the head and spool for properly orienting the head and the spool so that the respective contacts are in mutual angular alignment. A sliding door may be provided in the adaptor spool for covering the spool contacts when not in use, the door being raised by the slips when radially expanded, so as to expose the contacts.
