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.
The Type S13 oil-immersed distribution transformer is based on the original S11 distribution transformer, incorporating new materials and technologies through independent innovation and technology introduction. Optimized core and coil structure design reduces no-load loss and noise by an average of 20% compared to JB/T10088-2004 standards, achieving domestic advanced performance levels.
Ideal distribution equipment for urban and rural distribution network centers.
