Oil-immersed Distribution Transformer
Product Characteristics
S11 type 10KV and 35KV distribution transformers performance and characteristics are preventing oil deterioration and insulation from moisture and aging, low noise, low loss and strong ability to resist short circuit to ensure that it will not loosen during operation after long-distance transportation which are widely used in metallurgy, mining, petrochemical and other occasions with harsh environments.S13 type 10KV performance and characteristics: S13 type oil-immersed transformer is the energy-saving product with the best performance index of laminated core structure transformer at present. It has small magnetic leakage, high mechanical strength and strong short-circuit resistance, which improves the internal insulation strength of the transformer with new structural design and production process.
