Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a masterfully engineered, fully sealed oil-immersed power transformer from Zhejiang Chaotai Complete Equipment Co., Ltd. This extraordinary transformer is renowned for its exceptional energy efficiency, minimal noise output, and lower energy loss, making it a beacon of sustainable power solutions. By significantly reducing environmental pollution, it defines itself as a model of eco-friendliness. Departing from conventional designs, this innovative transformer forgoes the oil conservator, instead relying on the corrugated oil tank's elasticity to control oil volume changes autonomously. This ensures a complete seal from air, safeguarding against oil degradation and extending insulation life, thereby enhancing reliability and maintenance-free operation.
