Hermetically Sealed Oil-immersed Distribution Transformer
250KVA 315KVA Three-Phase Oil-Immersed Step-Down Distribution Transformer
PRODUCTS DESCRIPTION
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 Type S13 oil-immersed distribution transformer is widely used in residential areas, commercial centers, industrial parks, and rural electrification projects.
- Higher Energy Efficiency: Uses high-quality silicon steel sheets and optimized magnetic circuit designs, reducing no-load losses by 20–30% compared to S11 models.
- Improved Temperature Rise Performance: Enhanced oil circulation and cooling systems help maintain stable operation under load. Better thermal management leads to longer insulation life.
- Reduced Noise Levels: Use of high-permeability silicon steel and precision manufacturing lowers magnetostriction, resulting in quieter operation.
- 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.
- Longer Service Life: Better materials and structural improvements lead to extended service life, often reaching 20–30 years under proper conditions.
