Product Description
Oil Immersed Series Transformer:
Introducing the groundbreaking S11-M series, a fully sealed oil-immersed power transformer innovatively crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. This remarkable transformer is a beacon of modern engineering, renowned for its impressively low energy loss, ultra-quiet performance, and extraordinary efficiency. It represents a pinnacle of energy conservation, dramatically reducing pollution and minimizing its ecological footprint. Unlike conventional oil-immersed transformers, this advanced model is designed without the need for an oil conservator. Utilizing the innovative elasticity of the corrugated oil tank, it autonomously manages and compensates for oil volume changes while maintaining a perfectly sealed environment, protecting the transformer from air exposure. This transformative feature effectively safeguards against oil deterioration, significantly prolongs the lifespan of insulation, and greatly enhances operational reliability—all achieved without requiring routine maintenance in typical use.
