JiangSu FengGuang Transformer Co., Ltd. is located in Weiji Industrial Park, Zhangji Town, Tongshan District, Xuzhou City, Jiangsu Province. Covering nearly 15,000 square meters, it is equipped with more than 20 sets of various production equipment. It is a comprehensive manufacturer integrating power transformer R&D, manufacturing, and sales. The company also operates under the name JIANGSU FENGGUANG TRANSFORMER CO., LTD. It is a qualified supplier for State Grid, China Southern Power Grid, a national energy-saving product promotion enterprise, and a national high-tech enterprise, providing products and project services to more than 50 countries and regions worldwide. The company was the first among peers to pass three major certifications: ISO 9001 Quality Management System, ISO 14001 Environmental Management System, and ISO 45001 Occupational Health and Safety Management System. It has obtained AAA corporate credit rating, AAA credit unit, AAA contract-honoring and trustworthy unit, and other 3A credit certificates, as well as CE international product certification. The products strictly comply with GB 1094.1-1996, GB/T 6451-2008 national standards, and IEC 60076 series international standards, and have obtained multiple utility model patents and trademark registrations including "An Oil-immersed Transformer," "A Transformer, Transformer Oil Injection System and Injection Method," "Protective Transformer," "Dry-type Transformer with Uniform Cooling Structure," and "A Dry-type Transformer." Our main products include S11, S13, S20, S22 series 10kV/35kV oil-immersed power transformers, SCB10-SCB18 series dry-type transformers, SCBH15 and SCBH17 amorphous alloy dry-type transformers, SGB series and various prefabricated and combined box-type substations, and GGD low-voltage complete switchgear covering full capacity ranges from 50 kVA to 10,000 kVA, capable of undertaking custom orders for non-standard voltage, special capacity, altitude, and anti-corrosion protection. Entering the wind and solar factory: the silicon steel sheet longitudinal slitting lines precisely cut coils of silicon steel. The automatic winding machine tightly winds copper windings onto the insulating frame. At the assembly stations, the body is lined up in a straight line, with each wire tightened one by one. The vacuum impregnation paint tank, together with the online inspection and aging testing stations, forms a precise control system from material selection to every process step. The company adheres to the philosophy of "people-oriented, technological innovation, and strives for surpassing," and with reliable product quality and comprehensive after-sales service, we are committed to creating win-win outcomes with new and existing customers.
Selected models engineered for long service life and stable operation.
Energy efficiency Class 1 oil-immersed power transformer, S20/S22 series, with capacities ranging from 50 to 10,000 kVA. Focused on energy-saving acceptance and grid expansion projects, it supports configuration for 35kV voltage level and high-temperature/high-humidity environments.
S13-M-1000/10 oil-immersed power transformer, 1000kVA, 10.5/0.4kV, Dyn11 connection, no-load loss ≤870W. Suitable for the high-temperature, dusty conditions in the Middle East and the salt-spraying, humid environment in Southeast Asia. Comprehensive IEC 60076 test reports are provided.
The full range of dry transformers from SCB10 to SCB18, featuring both epoxy casting and VPI vacuum pressure impregnation manufacturing processes, with capacities ranging from 315–4000 kVA, low partial discharge and low noise, exported to more than 50 countries.
SCB13-1000/10 epoxy resin cast dry transformer, 1000kVA, 10.5/0.4kV, fire-resistant, low noise, low discharge, compliant with IEC 60076-11, suitable for data centers, hospitals, and commercial buildings.
ZGS20-Z·-40.5/0.69-4000 wind power/pv combined substation, 40.5kV high-voltage double-break protection, fully sealed structure, compact footprint, has passed type inspection, designed to quickly boost voltage and connect to the grid for new energy sites.
YB-12/0.4-2500 pre-assembled (European-style) substation, integrating high-voltage switchgear, transformer, and low-voltage distribution cabinets; delivered as a complete unit, with third-party inspection reports, suitable for rapid installation in industrial parks and urban distribution networks.
SCBH15 Amorphous Alloy Power Distribution Transformer series, 160–2500 kVA, with ultra-low no-load losses, is an upgraded alternative to S13 in energy-saving renovations and photovoltaic supporting projects.
SCBH17-2000/10-NX2 Amorphous Alloy Dry Transformer; The no-load loss is more than 70% lower than that of S13 silicon steel of the same capacity. It meets the energy efficiency standards and is preferred for new energy power stations, with a third-party inspection report available.
From product selection and technical design to testing, delivery and after-sales service.
Real installations delivered to customers worldwide.
Company updates, product releases and industry insights.
Same capacity but different frequency; the core cross-section, turns, impedance, and noise are all different: Designed for 60Hz markets like the Philippines, it explains why 50Hz inventory cannot be applied and how to avoid overheating due to high magnetic flux.
Based on three aspects: no-load loss, load loss, and total cost of ownership, we analyze the selection logic and recovery period calculation method for upgrading from S13-M to high-efficiency level S20/S22.
A list of 21 third-party inspection reports covering popular models such as S13-M, SCBH17-NX2, YB pre-installed, and ZGS modular, has been officially released for EPC and distributors to directly refer to in bidding processes.
Jiangsu Fengguang Transformer recently completed the supervision and audit of the three systems: quality, environment, and occupational health and safety, and extended the certificate validity period. The quality control and EHS processes cover the entire process, from silicon steel cutting to factory testing.
