Testing the Limits: 1250kVA 15kV Oil Immersed Transformer for Extreme Climates

From tropical ports to desert substations, power transformers face punishing conditions. Guangzhou Aputon Electrical Co., Ltd. designed its 1250kVA 15kV Oil Immersed Transformer to thrive where others fail.

The oil-immersed structure naturally excels at heat dissipation, but we go further: high-grade core steel minimizes losses, while the sealed tank options prevent moisture ingress and oxidation. For applications with frequent lightning or voltage surges — common in 15kV overhead line networks — the transformer’s insulation coordination meets or exceeds IEC 60076 standards.

Since our founding in December 2015, Aputon has supplied equipment to regions with diverse climates, including high-altitude Southeast Asia and cold-start European winters. Our 1250kVA 15kV unit can be equipped with oil preservation systems (conservator or sealed) and explosion-proof pressure relief devices.

Certified under ISO9001, ISO14001, and OHSAS18001, we test each transformer for short-circuit withstand capability and partial discharge levels. For mining sites, outdoor switching stations, or heavy industrial zones, this transformer delivers decade-long reliability.
