ZGS New Energy Modular Combined (Transformer/Substation)

This product features an oil-filled, hermetically sealed structure with the same operating principle as hermetically sealed power transformers. The amorphous alloy core is composed of elements such as iron, nickel, cobalt, silicon, boron, and carbon. As an isotropic soft magnetic material, it offers low magnetizing power and no structural defects hindering domain wall movement. With an ultra-thin thickness of just 0.027 mm, its stacking factor is correspondingly low at 0.75–0.8. The material also provides extremely high electrical resistivity (3 to 6 times that of silicon steel sheets) and five times the hardness of silicon steel sheets, though it is particularly sensitive to mechanical stress.

This product series features an advanced design, with significant improvements in materials, structure, and manufacturing processes. It offers strong short-circuit withstand capability, elegant appearance, reliable operation, low losses, and low noise, reaching a level comparable to advanced foreign products of the same type. The prototype of our SZ9-20000/35 transformer successfully passed the sudden short-circuit test conducted by the National Transformer Testing Center on the first attempt. The longitudinal oil channels provided in the high- and low-voltage coils facilitate heat dissipation, significantly reducing the copper-oil temperature difference and the hot-spot temperature rise inside the coils.

This product boasts a wide range of applications and is particularly suited for installations with high fire safety requirements. These include mines, oil fields, subways, power plants, schools, hospitals, commercial centers, high-rise buildings, and all types of indoor distribution systems.

The S22-M fully sealed oil-immersed power transformer is suitable for use in power systems with an AC frequency of 50 Hz and a rated operating voltage of 10 kV or less. It is used as a distribution transformer in enterprises such as petroleum, metallurgy, chemical, textile, and light industry, as well as in locations with high levels of dust. The product complies with the standard: GB1094.1-5.

As China's economic development continues to advance, improvements in living standards, increased electricity demand, and the proliferation of transformer equipment have led to significant energy consumption and heightened noise levels, severely polluting urban environments. As a result, countries worldwide are calling for and taking steps to reduce energy consumption and improve urban environments. The S13-M fully sealed oil-immersed transformer, compared to the currently used S9 and S11 types in urban grid construction, achieves an average reduction in no-load losses of 50% and 30%, respectively, and a noise level reduction of 5–8 dB.
