China Manufacturers Enamelled Aluminum Electric Submersible Winding Wires is used in the manufacture of submersible motor windings. Submersible motors are mostly used for oil extraction in oil mines and work at high temperatures. In order to maintain the internal and external pressure balance, the interior including the windings are immersed in high-pressure (for example, 10 MPa) water-containing oil. In order to avoid joints, the windings are mostly made of a single magnet wire repeatedly wound in the slot of the motor, so the insulation layer is required to have good wear resistance. Usually polyimide film is used to wrap the covered wire.
