The design was completed using state-of-the-art standard 3D design software and reliable electric field calculation technology. It was designed based on the worst short-circuit conditions, and the welded oil tank has a reasonable structure with high mechanical strength. High-quality seals and special designs are used to prevent oil leakage.
High Performance
Oil-immersed transformers use transformer oil as the medium, combining high insulation strength with excellent heat dissipation performance. They can prevent discharge and moisture, and efficiently remove heat, ensuring reliable operation.
Safety
Oil-immersed transformers are equipped with oil conservators, gas relays, pressure relief valves, and dehumidifiers to achieve fire and explosion prevention and fault early warning, ensuring safe and reliable operation.
Low Maintenance
Oil-immersed transformers utilize oil to maintain their components, achieving low-maintenance, long-term operation.
