Problems solved by technology

[0002] At present, the winding wires of submersible motors mostly adopt the structural form of polyethylene insulated nylon sheath. In order to ensure the insulation performance under high voltage, the thickness of the insulating layer must be increased, which greatly occupies the precious space of the stator slot of the motor, making the high-voltage submersible motor The volume becomes larger, which reduces the efficiency of the submersible motor
