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. 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 ADVANTAGES

The advantages of Type S13 oil-immersed distribution transformer

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.
