Manufacturer Wholesale ISO9001 Certified 400KVA 500KVA Oil-immersed Power Transformer
Fully sealed tank with anti-corrosion coating and top-grade transformer oil. Keeps insulation oil pure and prevents moisture ingress. More than 20 years of service life with minimal maintenance required.
Winding uses oxygen-free copper with high insulation and mechanical strength. Short-circuit resistant with low thermal rise. Stable long-term operation with low maintenance costs.
Certified by ISO9001, ISO14001, CE, etc. Meets global safety and environmental compliance. Suitable for global export: EU, US, Middle East, Africa, SEA.
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. Self-developed products.
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.
