Product Description

Hentg Power Transformer 250kVA 315kVA 10KV 400V Three Phase Oil Immersed Transformer Copper Winding Dyn11. Built with high-quality cold-rolled silicon steel sheets and oxygen-free copper windings, minimizing no-load and load losses.

Lower core and copper losses than IEC standards, reduced temperature rise, and environmentally friendly. Reduces long-term operational costs while improving system stability and grid efficiency.

Type S13 oil-immersed distribution transformer is based on the original S11 distribution transformer, through the research and application of new materials and new technologies and the combination of independent innovation and technology introduction, through the optimization and innovative design of the core and coil structure, to reduce the no-load loss and noise purposes. Compared with the current national standard JB/T10088-2004, the noise level decreased by 20% on average, and the product performance level reached the domestic advanced level.

Ideal distribution equipment for urban and rural distribution network centers.
