Description

Our oil-immersed distribution transformers range from 30kVA to 2500kVA, with voltage levels up to 35kV. They are widely used in power utilities, renewable energy, industrial facilities, railway systems, and urban infrastructure. Designed to IEC and ANSI standards, our transformers offer high efficiency, low losses, and long service life, suitable for both indoor and outdoor environments.

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