10kv_oil_immersed_distribution

Modern 10kV transformers are usually energy-saving models, with significantly reduced no-load losses and load losses.Compared with transformers of higher voltage levels, 10kV transformers occupy a smaller area and are suitable for distribution rooms or outdoor box-type substations with limited space.Adapt to the motor, lighting and other load requirements of small and medium-sized factories.

TSTY Transformer Advantages

Raw materials

The core is made of high-quality steel sheets from Baosteel/Wuhan Iron and Steel, which are cut by shearing machines with very few burrs. The multi-step 45-degree inclined seams effectively reduce no-load loss, no-load current and noise.

Excellent insulation performance

The insulation uses Nomex® paper, which is resistant to high temperatures. The production process uses vacuum oiling and drying environment, high-temperature resistant insulating oil, etc., which greatly improves the insulation performance.

Copper winding

The use of copper winding makes the conductive performance outstanding, and it can cope with extreme environments such as high humidity and high temperature, and the service life can reach more than 30 years.

Transformer body

The TSTY transformer body is made of high-quality steel plates and plates, which meet national standards and have high mechanical strength and durability.

R&D Advantages

TSTY has more than 200 R&D personnel and has invested in building a science and technology innovation center to develop production processes and materials. TSTY has a CNAS-certified laboratory. Each transformer produced has passed more than ten rigorous tests such as lightning impact and insulation no-load to ensure stable operation in various harsh environments. All products have passed CE, IEC, SGS, BV, GOST and other certifications, reflecting that the products meet the country's strict quality standards and safety regulations.
