Product Overview
Our oil-immersed distribution transformers range from 30kVA to 2500kVA, with voltage levels up to 35kV. They are widely used in power utilities, renewable energy, industrial facilities, railway systems, and urban infrastructure. Designed to IEC and ANSI standards, our transformers offer high efficiency, low losses, and long service life, suitable for both indoor and outdoor environments.
Key Features
- Cooling Options & Installation Flexibility: Supports ONAN (Oil Natural Air Natural) and ONAF (Oil Natural Air Forced) cooling options. Adaptable to indoor/outdoor, pad-mounted, or pole-mounted installations.
- Top-Grade Materials: Winding uses oxygen-free copper with high insulation and mechanical strength. Short-circuit resistant with low thermal rise.
- S13 Series Advantages: Built with high-quality low-loss silicon steel and advanced coil winding technology.
