Product Description

S Series 35kV ~ 66kV three-phase oil-immersed power transformers are medium-high voltage energy-saving power transformation equipment. Featuring low loss, low noise, high mechanical strength and strong short-circuit resistance, this series supports on-load and off-circuit tap regulation. Fully sealed oil-immersed structure ensures maintenance-free operation, ideal for power grid construction, industrial parks, mining, solar and wind power plant power distribution projects.

Core Features

- Superior Energy-saving Performance: Adopts advanced step-lap core stacking technology, effectively reducing magnetizing loss and no-load current, lower operation cost and higher energy efficiency.

- Strong Short-circuit Resistance: Reinforced winding fastening structure and optimized electromagnetic design prevent winding displacement and deformation under short-circuit impact, ensuring operational safety.

- Dual Voltage Regulation Options: Equipped with off-circuit tap changer as standard; on-load tap changer (OLTC) is optional to meet uninterrupted voltage regulation demands.

- Reliable Sealed Structure: Integrally welded fully sealed oil tank, no oil leakage, anti-moisture and anti-oxidation performance, stable insulation performance for long-term outdoor operation.

- Flexible Cooling System: Supports ONAN/ONAF dual cooling modes, efficient heat dissipation, low temperature rise, suitable for continuous full-load and overload operation.

- Wide Environmental Adaptability: Adaptable to high altitude, high temperature, high humidity and dusty harsh environments, widely used for outdoor and indoor power distribution.

- International Standard Compliance: Manufactured strictly in accordance with IEC 60076 international standards, with stable performance and complete quality certification.
