  • Cable splice method using transition rod
    Patent number: 4610737
    Abstract: A method of splicing a submersible pump motor lead to a power cable provides a smaller splice. A transition rod is welded between each motor lead conductor and power conductor. The transition rod has a smaller diameter on one end to connect to the diameter of the motor lead. The larger diameter end has a cavity for receiving the power cable conductor. After welding, an insulating layer is molded around each rod. Then, an elastomeric jacket is molded around all three of the rods.
