The company also operates under the name JIANGSU FENGGUANG TRANSFORMER CO., LTD. It is a qualified supplier for the State Grid, China Southern Power Grid, a national energy-saving product promotion enterprise, and a national high-tech enterprise. It has provided products and project services to over 50 countries and regions around the world. The company is the first in its industry to obtain three certifications: ISO 9001 Quality Management System, ISO 14001 Environmental Management System, and ISO 45001 Occupational Health and Safety Management System. It has also received 3A credit certificates, including AAA-level credit rating, AAA-level trustworthy unit, and AAA-level contract-abiding unit. Additionally, it holds CE international product certification. Its products strictly comply with national standards such as GB 1094.1-1996 and GB/T 6451-2008, as well as international standards like IEC 60076. The company has obtained multiple utility model patents and trademark registration certificates, including "an oil-immersed transformer," "a transformer, transformer oiling system, and oiling method," "transformer (protective type)," "a dry-type transformer with a uniform heat dissipation structure," and "a dry-type transformer." The main products include S11, S13, S20, and S22 series 10kV/35kV oil-immersed power transformers, SCB10-SCB18 series dry-type transformers, SCBH15 and SCBH17 amorphous alloy dry-type transformers, SGB series, as well as various pre-assembled and combined box-type substations. It also provides GGD low-voltage switchgear, covering full capacity ranges from 50 kVA to 10,000 kVA. The company can handle non-standard voltage, special capacity, altitude, and anti-corrosion customized orders. Entering the wind power factory: The silicon steel strip slitting line precisely cuts the rolled silicon steel into strips, the automatic winding machine tightly winds the copper windings on the insulation framework, and at the assembly station, the components are arranged in a line and each unit's leads are secured individually. The vacuum oiling tank, along with on-line testing and aging test stations, form a precise control system from material selection to each process step. Adhering to the philosophy of "people-oriented, technological innovation, aiming for excellence," the company offers reliable product quality and comprehensive after-sales service, hoping to create a win-win situation with new and existing customers.
