SH Power provides full-life-cycle support for its transformers, encompassing solution design, model optimization, and on-site commissioning—all delivered by our highly experienced technical team. We offer tailored solutions for diverse applications to guarantee highly efficient operations and maximize energy savings.

Description

110kV and 220kV power transformers are widely used in power generation, transmission, distribution, new energy, rail transit, industrial and commercial projects, and other fields. The SFZ22-240000/220 transformer manufactured by our company has successfully passed all routine type tests, including the short-circuit endurance test conducted by the National Electrical Products Quality Inspection and Testing Center.

We provide products with a wide range of models and capacity configurations, including S(F)Z20/22 double-winding on-load tap-changing transformers, SS(F)Z20/22 three-winding on-load tap-changing transformers, and S(F)20/22 double-winding off-circuit tap-changing transformers. These various specifications are designed to meet the diverse customized needs of customers.

Product Features
