Description:

Oil-immersed transformers for power transmission have large capacity, long service life, and stable operation. They are the key hubs for long-distance power transmission in the power grid.

1.Large Capacity

With high-power transmission capabilities starting from several thousand kVA, they can easily collect and distribute huge amounts of electrical energy in large power grid hubs, meeting the peak electricity demands of cities and industrial clusters.

2.Long Service Life

High-quality iron cores and windings, combined with insulating oil for heat dissipation and insulation, can ensure decades of service life with regular maintenance, reducing equipment replacement costs and the frequency of power outage maintenance.
