With over 470 units of various production equipment, the company has an annual production capacity of up to 10 million kVA of transformers with voltages up to 220 kV and also manufactures various complete switchgear assemblies. The company is a qualified EPC general contractor in the electric power industry and has its own in-house construction technical team. It is a top-tier enterprise in China for the development and production of transformers, with advanced integrated construction capabilities, and is among the leading private transformer manufacturers in the country.
The company operates 11 administrative divisions, including the Administrative Department, Finance Department, Marketing Department, Production Department, Technical Department, Quality Management Department, Procurement Department, Warehouse Department, Sales and Service Department, Energy Engineering Division, and Legal Department. Currently, the company employs over 260 staff members—including more than 60 employees with disabilities, 4 senior engineers, and 12 engineers. The company holds 15 patents for inventions and 46 patents for utility models. Its core activities encompass the R&D, manufacturing, sales, installation, construction, and technical maintenance of energy-efficient power transformers, intelligent packaged substations (KTP), as well as high- and low-voltage switchgear and complete equipment sets.
The company's main products include 10kV, 35kV, 110kV and 220kV transformers, including S11, S13, S18, S20 and S22 series oil-immersed transformers, S11-M-R 10kV wound core transformers, SH15 series amorphous alloy transformers, SCB10, SCB11, SCB12, SCB13, SCB14, SCB18 and SGB series dry-type transformers, and SCBH series amorphous alloy dry-type transformers. In addition, the company produces complete substations for new energy, furnace transformers, rectifier transformers, mine transformers and other special transformers, as well as complete substations, high- and low-voltage distribution cabinets, reactors, reactive power compensation units, linear voltage regulators and related components such as transformer tanks, winding wires, magnetic cores and insulating components.
All products are developed in-house by the company's technical staff. Among them, the S11-M.R transformer with a wound magnetic core was awarded the "National New Product" title. In collaboration with Shandong University of Science and Technology, an automated design system was developed for the S20 and SCB18 transformers, reducing production costs by approximately 6%. The company is also independently developing cast dry-type transformers made of amorphous alloy with epoxy insulation, which have already entered mass production. The S13-M.RL transformer with a three-dimensional magnetic circuit and a power-adjustable transformer have also received national energy-saving certification.
The company has a full complement of production equipment fully compliant with the requirements for the production of transformers up to 220 kV. This includes slitting and cutting lines, silicon steel bending and cutting equipment, magnetic core winding machines, automatic winding machines, busbar processing equipment, foil winding machines, vacuum drying units, vacuum casting and vacuum impregnation units, as well as stamping, cutting, bending, washing, and powder coating equipment—more than 470 units in total. This includes 47 units of testing equipment, including comprehensive test benches, lightning surge voltage generators, voltage regulators, intermediate transformers, frequency doublers, and high-voltage testing systems, enabling full factory testing and product quality assurance.
The company's products are primarily supplied to the State Grid Corporation of China and are also widely used in the domestic end-use market. They are also exported to the Philippines, the Middle East, Central Asia, and Kenya. The company has established long-term partnerships with renowned Chinese companies such as China Electric Equipment Group, TBEA, and China Nonferrous Metal Industry Group.
