ABSTRACT:
A cable anchor assembly (16) for an inverted, cable deployed submersible pump (28) that comprises a cable tensioning device (18) adapted to preload the multwire rope members (38) of the power cable (30). The cable tensioning device (18) comprises threaded upper (32), middle (34) and lower (36) sleeves, and the length of the device is manually adjustable by rotating the middle sleeve (34) relative to the upper (32) and lower (36) sleeves to increase or decrease tension on the multiwire rope members (38) of the power cable (30) as desired. The longitudinal bore (42) of the cable tensioning device (18) is adapted to accommodate and protect power delivery members (40) that extend through the bore for connection to the prime mover of the submersible pump.
