SC(B)18 type double-winding non-excitation tap-changing dry-type distribution transformer of 10kV

The dry-type transformers produced by our company,which meet all the

standards in terms of performance indicators. As verified by users, they

operate reliably and reach the advanced level of the country. This series of

products adopt advanced manufacturing technologies from abroad. The

design drawings and technical documents are complete, correct and clear.

The production equipment is advanced, the manufacturing process is

stable, and the measurement methods are complete. This provides a solid

guarantee for the production of high-quality products. This product has

low performance loss, good energy-saving effect, economical operation,

and maintenance-free. In addition to the advanced process structure, high

anti-short-circuit and lightning impact levels, it also has the characteristics

of flame retardancy, moisture resistance, dust resistance, and low noise. It

can be deeply located at the load center. It is widely used in high-rise

buildings, airports, stations, docks, power plants, substations, etc. It is

particularly suitable for installation and use in places with high fire

prevention requirements such as places with flammable and explosive

substances. It is the best choice for modern commercial centers and other
