PE2+PA Insulated Submersible Winding Wire: Core Applications

• Agricultural Irrigation & Groundwater Extraction: This type of winding wire is widely installed in submersible pump motors for farmland irrigation, deep-well water intake and no-tower water supply systems. Its excellent waterproof and pressure-resistant properties allow submersible pumps to operate stably in deep groundwater at depths of hundreds of meters, supporting continuous water supply for large-scale agricultural irrigation projects. It can adapt to long-term operation in low-temperature, high-humidity underwater environments, effectively extending the service life of submersible motors and reducing equipment maintenance costs for agricultural users.
• Industrial & Municipal Water System: In urban water supply, industrial drainage, sewage treatment and fire protection water supply systems, PE2+PA insulated submersible winding wire serves as the core winding material for various submersible pump motors. It maintains stable insulation performance under frequent start-stop conditions and variable frequency operation, meeting the continuous and reliable operation requirements of municipal and industrial water treatment facilities. Its high mechanical strength also prevents insulation damage during long-term underwater operation, ensuring the safety and stability of the entire water supply system.
• Special Fluid Environment Operations: For submersible equipment working in complex media such as mine drainage, geothermal heating, petroleum exploration and saltwater environments, the PE2+PA winding wire can be customized with acid, alkali and salt resistant formulations. It effectively resists erosion from various corrosive liquids, and can operate normally in high-temperature environments up to 150℃, making it suitable for special submersible motors in mineral extraction, offshore engineering and geothermal development projects.

Key Performance Advantages

• Superior Liquid Impermeability: The dual-layer PE2+PA structure completely blocks the penetration of water, oil and other liquids, avoiding insulation breakdown failures caused by medium intrusion inside the motor.
• Excellent Mechanical Properties: The outer PA sheath provides strong tensile and wear resistance, protecting the inner insulation layer from mechanical damage during motor winding and long-term underwater operation.
• Wide Adaptability: The product covers conductor specifications from Φ0.3mm to Φ6.0mm, supporting operating voltages from 380V to 10kV, and can be customized for high temperature resistance, high voltage resistance and variable frequency resistance according to different working conditions.
• Long Service Life: With decades of verified practical application experience, this winding wire can ensure trouble-free operation of submersible motors for more than 10 years under standard working conditions, significantly reducing the overall lifecycle cost of submersible equipment.

During the winding process, avoid sharp bending and excessive stretching of the wire to prevent damage to the outer PA protective layer. After the motor is assembled, perform a water pressure withstand test in accordance with relevant standards to confirm the sealing performance of the winding part. For high-voltage scenarios above 3kV, it is necessary to configure a semiconducting layer as required by the specification to optimize the electric field distribution inside the insulation and avoid partial discharge problem
