Product Characteristics
1. Use Polyimide film wrapped flat copper wire.
2. It has excellent electrical properties, high mechanical properties and good resistance to moisture and heat.Suitable for large and medium-sized high voltage motors, special motors and electrical windings
3. The winding is immersed in insulating oil, and the high heat capacity and fluidity of the oil can quickly remove the heat generated by the winding, avoiding local overheating and improving the overall heat dissipation efficiency of the transformer.
4. High insulation reliability
-Insulation oil fills the winding gap, effectively isolating the conductor from air and reducing the risk of partial discharge and breakdown.
5. Strong mechanical stability
-The winding adopts copper wire or transposed wire, which is fixed by a clamping structure to resist the huge electromagnetic force during short circuit and prevent deformation or displacement.
6. Overload resistance and aging resistance
-Oil circulation slows down the oxidation of insulation materials and extends the lifespan of windings.
-High temperature resistant materials support short-term overload operation.
7. Noise reduction and environmental protection
-Oil medium suppresses winding vibration noise and meets the noise standards of urban power grids.
