Step Up Down Mv Hv Oil Immersed Distribution Transformer Electrical Power Transformer

Step up/down 50kVA 100kVA 200kVA MV HV Oil immersed distribution transformer electrical power transformer

Our oil-immersed distribution transformers are widely used in power transmission, industrial and commercial electricity, renewable energy systems, and urban infrastructure. With a capacity range from 30kVA to 2500kVA and voltage levels up to 35kV, these units feature low loss, high reliability, and stable operation, fully compliant with IEC, ANSI, and other international standards.

• Fully sealed tank with high-quality insulating oil for cooling
• Efficient heat dissipation, reducing operating temperature
• Extends transformer lifespan and improves operational safety

The Type S13 oil-immersed distribution transformer is widely used in residential areas, commercial centers, industrial parks, and rural electrification projects. Compared to S9 or S11, the S13 offers several improvements:

1. Higher Energy Efficiency
   Lower no-load loss: The S13 series uses high-quality silicon steel sheets and optimized magnetic circuit designs, reducing no-load losses by 20-30% compared to S11 models. Lower load loss: Improved winding structure and materials reduce resistance and load losses, improving overall efficiency.
2. Improved Temperature Rise Performance
   Enhanced oil circulation and cooling systems help maintain stable operation under load. Better thermal management leads to longer insulation life.
3. Reduced Noise Levels
   Use of high-permeability silicon steel and precision manufacturing lowers magnetostriction, resulting in quieter operation.
4. Robust Mechanical Design
   Improved short-circuit resistance due to optimized winding structure and clamping. Core and coil assembly is more stable, reducing vibration and mechanical stress.
5. Longer Service Life
   Better materials and structural improvements lead to extended service life, often reaching 20-30 years under proper conditions.
