1. [0001] The utility model in this paper belongs to the field of submersible motors, and secondly relates to the power cable lead T6670 of a submersible motor winding.

2. [0002] In view of the fact that submersible motors are used in water, X35KB96SG insulating materials need to be able to have good electrical insulation properties from water for a long time. In addition, they can be sealed and isolated from water and non-electric contact.

3. Especially in the 100 more than 20 years since submersible motors were put into use, it is estimated that about 50% of motor operation faults are at least electrical faults, but the second time electrical faults are insulation breakdown if the insulation resistance is low.

4. The vast majority of damaged parts that cause faults are the connection parts between windings and lead-out cables. How can we design this novel approach to make the breakdown problem never occur, thus solving these long-standing problems that have affected the reliability of motors for many years and becoming a research topic for technicians in this field.
