[0001] This utility model relates to the field of submersible motor technology, and in particular to a high-temperature resistant, oil-resistant, water-resistant submersible motor winding wire with a high PDIV value. Background Technology
[0002] The global market for submersible motor windings has maintained steady growth over the past few years and is expected to continue growing in the coming years. As underwater activities become increasingly complex, higher demands are being placed on submersible motor windings. Currently, the high-temperature resistance, oil and water resistance, and insulation performance of submersible motor windings are affected by prolonged operation in complex underwater environments, impacting their performance and lifespan. Therefore, we propose a high-PDIV value submersible motor winding that is resistant to high temperatures, oil, and water. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature, oil-, and water-resistant submersible motor winding wire with a high PDIV value. This wire significantly improves the temperature resistance, oil and water resistance, and insulation performance of the submersible motor winding wire. Furthermore, it possesses corrosion resistance, wear resistance, and weather resistance, making it suitable for operation in complex underwater environments. This invention solves the current problems of insufficient temperature resistance, water resistance, and insulation performance in submersible motor winding wires, thereby increasing their performance and lifespan in complex underwater environments.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The advantages are: it significantly improves the temperature resistance, oil and water resistance, and insulation performance of the submersible motor winding wire. Simultaneously, this winding wire also possesses corrosion resistance, wear resistance, and weather resistance, making it suitable for operation in complex underwater environments. It solves the current problems of insufficient temperature resistance, water resistance, and insulation performance in submersible motor winding wires, increasing their performance and lifespan in complex underwater environments. It exhibits excellent high-temperature resistance, oil and water resistance, high PDIV value, corrosion resistance, and wear resistance.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0017] Reference Figure 1A high-temperature resistant, oil-resistant, and water-resistant submersible motor winding wire with a high PDIV value includes a conductor 1. The conductor 1 has a first oil-resistant and water-resistant polyimide enamel layer 2 on its outer side. The first oil-resistant and water-resistant polyimide enamel layer 2 is wrapped with a high PDIV value polyimide enamel layer 3 on its outer side. The high PDIV value polyimide enamel layer 3 has a second oil-resistant and water-resistant polyimide enamel layer 4 on its outer side. The second oil-resistant and water-resistant polyimide enamel layer 4 has a water-blocking adhesive layer 5 on its outer side. The water-blocking adhesive layer 5 has an insulating sheath layer 6 on its outer side.
[0018] Conductor 1 is made of oxygen-free round copper wire. Oxygen-free round copper wire ensures excellent conductivity while also having good oxidation resistance and high stability and corrosion resistance.
[0019] Both the first oil- and water-resistant polyimide enamel coating layer 2 and the second oil- and water-resistant polyimide enamel coating layer 4 are made of oil- and water-resistant polyimide enamel with a temperature resistance rating of 240°C. They have extremely high heat resistance and can maintain stable performance in high-temperature environments. They also have excellent oil and water resistance, solvent resistance, and good electrical insulation properties. The second oil- and water-resistant polyimide enamel coating layer 4 improves the insulation performance by increasing the thickness of the enamel film, while further enhancing the oil and water resistance of the winding wire.
[0020] The high PDIV value polyimide varnish 3 uses high PDIV value polyimide varnish with a temperature resistance rating of 240°C, which has extremely high heat resistance. The high PDIV value means that partial discharge will only occur at higher voltages, which greatly improves the insulation performance. At the same time, it also has high surge resistance. Under sudden high voltage or current surges, the polyimide varnish can ensure stable insulation and prevent equipment failure or damage.
[0021] The water-blocking adhesive layer 5 uses high-temperature water-blocking tape and high-temperature water-resistant adhesive, which further improves the water resistance while ensuring that the second oil- and water-resistant polyimide enamel coating layer 4 and the insulating sheath layer 6 are tightly bonded together without gaps, thereby improving the stability of the cable structure.
[0022] The insulating sheath layer 6 is made of polytetrafluoroethylene (PTFE). PTFE has excellent electrical insulation, water resistance, and abrasion resistance, as well as excellent high and low temperature resistance and strong chemical corrosion resistance, which can fully protect the internal conductive core.
