S13 Oil-immersed Transformer with Short-Circuit Impedance 4-6% and Output Voltage 220V 380V 400V 415V - CE Certified Oil Immersed Power Transformer

ype 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.

Our 50kVA oil-immersed transformer is a core power equipment designed for industrial and commercial applications. It utilizes proven oil-immersed cooling technology for efficient heat dissipation, ensuring the transformer maintains exceptional stability and reliability even under sustained high-load operation. Whether serving as a critical node in a power distribution system or providing stable power for specialized equipment, this transformer is a reliable choice. We adhere strictly to the ISO9001 quality management system to ensure that every product meets the highest standards.

High Efficiency and Energy Saving: Utilizing high-quality, high-permeability silicon steel laminations and pure/all-copper windings, this transformer significantly reduces both no-load and load losses, helping you save on operating costs and improve energy efficiency.

Excellent Heat Dissipation: The unique corrugated oil tank design increases the heat dissipation area. Combined with high-performance transformer oil, this transformer delivers high heat dissipation efficiency, low temperature rise, and extended equipment life.

Strong Overload Capacity: The robust internal structure and high-quality insulation materials provide the transformer with excellent short-term overload capacity, easily handling transient shock loads.

Safety and Reliability: Fully sealed or with an oil conservator design effectively prevents oil aging and insulation moisture. Safety features such as a pressure relief valve and thermometer ensure worry-free operation.

Low-Noise Operation: Optimized magnetic circuit design and vibration-damping structure ensure low operating noise, making it particularly suitable for noise-sensitive locations, such as commercial and residential areas.

Long-Life Design: High-quality insulating oil and high-temperature-resistant insulation materials ensure the transformer's design life of over 20 years, with minimal maintenance costs.
