Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, a pioneering creation by Chaotai Power, offers unparalleled advantages such as minimal loss, subdued noise, and exceptional efficiency. Designed for optimal energy conservation, this innovative transformer effectively reduces pollution. Unlike conventional oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. Its unique construction allows the oil volume to self-adjust and compensate via the flexible corrugated oil tank. This ensures the transformer remains air-isolated, safeguarding against oil degradation and insulation wear, thereby boosting operational reliability and eliminating routine maintenance.
