750V 100% Pure Copper Coil for Submersible Motor 1/2 HP Durable Submersible Pump Motor

Main Motor Types Matched with This Winding Wire

1. Submersible Motors for Water WellsThis is the most mainstream application scenario for this type of stranded winding wire, widely used in drive motors for deep-well pumps for agricultural farmland irrigation and domestic water intake submersible pumps. These motors operate in well water several meters or even hundreds of meters deep for a long time. The water-resistant insulation performance of the stranded winding wire can resist the long-term erosion of conventional well water with a pH value of 6.5~8.5, stably carry the working voltage of 380V-750V, and ensure the continuous and stable operation of the motor.
2. Submersible Motors for Mine DrainageSubmersible motors for underground mine drainage operations have extremely high requirements for the tensile resistance and wear resistance of winding wires. The stranded winding wire with multi-strand structure has far higher mechanical strength than single-strand wires, can withstand the vibration stress during long-term operation of the motor, and meets the insulation safety requirements in the complex underwater environment of the mine at the same time, avoiding safety hazards such as electric leakage and breakdown. It is the core supporting component of mine rescue and drainage motors.
3. Submersible Motors for Municipal Water Supply and DrainageA large number of submersible motors supporting sewage submersible pumps and water supply lifting pumps in urban water supply and drainage systems use this type of stranded winding wire. It can adapt to the corrosion environment of a small amount of acid and alkali impurities in sewage, and the long-term working temperature is stably controlled between 70°C and 90°C, ensuring the 24-hour uninterrupted operation of the municipal water system.
4. Special Submersible Motors for Marine EngineeringFor submersible propulsion motors and subsea sampling equipment drive motors used in seawater environments, upgraded corrosion-resistant stranded winding wires are adopted. By adding a nickel-plated layer outside the copper conductor and matching with a fluoroplastic composite insulation layer, it resists the electrochemical corrosion of high-salinity seawater and meets the special needs of marine resource development and underwater engineering operations.
5. Special Submersible Motors for Fire ProtectionSupporting submersible motors for fire deep-well pumps and emergency drainage submersible pumps use voltage-resistant stranded winding wires, which can pass the strict test of withstanding 3000V voltage for 1 minute without breakdown. They can still maintain stable insulation performance in fire emergency scenarios, ensuring the reliable start of the fire water supply system.

Core Performance Advantages of the Product

This stranded winding wire strictly follows the industry standard JB/T 4014.4-2013, with the wire diameter tolerance controlled within ±0.05mm. According to different specifications, it adopts a single-layer PVC insulation or double-layer PE + nylon composite sheath structure. Some high-temperature-resistant models have a temperature resistance grade of up to 150°C, which can adapt to the full series of submersible motor requirements from ordinary low voltage to 10kV high voltage. The stranded structure design gives the conductor excellent flexibility, which is not easy to cause insulation damage during the motor winding and embedding process, and effectively reduces the skin effect under high-frequency working conditions, making it suitable for the use requirements of frequency conversion-driven submersible motors.
