Product Description
Oil Immersed Series Transformer:
The S11-M series, a fully sealed oil immersed power transformer crafted by Zhejiang Chaotai Complete Equipment Co., Ltd., stands out with its remarkable low-loss, low-noise, and high-efficiency performance. This transformer not only offers outstanding energy-saving capabilities but also significantly minimizes pollution. Distinct from conventional oil-immersed transformers, this model innovatively eliminates the oil conservator. It features a corrugated oil tank where oil volume changes are seamlessly managed and compensated through the flexibility of the corrugated sheet. This design isolates the transformer from air exposure, effectively decelerating oil degradation and insulation aging, thereby enhancing operational reliability and obviating the need for maintenance during standard operation.
