Step Down Distribution Transformer

The core function of the step-down distribution transformers manufactured by Jiangxi Yihong Electric Power Technology Co., Ltd. is to step down high-voltage electricity to low-voltage levels suitable for distribution. These transformers are applicable for use in power plants, substations, industrial and mining enterprises, residential communities, and commercial buildings.

The high-voltage side of this step-down distribution transformer offers three rated voltage options-10kV, 6kV, and 35kV-while the low-voltage side is fixed at 0.4kV. The capacity range covers 30kVA to 2500kVA, operating at a frequency of 50Hz. The connection group is either Dyn11 or Yyn0; cooling methods include oil-immersed natural cooling (ONAN) or dry-type natural cooling (AN); the protection class is IP20 or IP23; impedance voltage ranges from 4% to 6%; and off-circuit tap changing (±2×2.5%) is employed for voltage regulation. The products comply with the GB/T 6451 and IEC 60076 standards.

The company's intelligent manufacturing base is located in the Chating Industrial Park, Guangxin District, Shangrao City, Jiangxi Province. Covering an area of ​​10,000 square meters, the facility is equipped with a laser cutting system (with an accuracy of ±0.05mm) and robotic welding workstations (with a defect rate of ≤0.01%). This high-precision equipment serves as a solid guarantee for the exceptional quality of our step-down distribution transformers.

Prior to sale, we provide quotations and design proposals; during the sales process, we maintain close communication; and after the sale, we conduct periodic follow-up visits while offering on-site commissioning and routine inspection services. Before leaving the factory, every product undergoes a rigorous three-stage quality inspection process, followed by a 100% comprehensive check prior to packaging. We offer a one-year warranty, accept third-party inspections, and provide assistance with claims in the event of transit damage.

Payment Terms: 50% upfront payment, 50% final balance. We support EXW and FOB trade terms and accept payments in RMB, USD, and EUR. Discounts are available for large-volume orders. Export packaging utilizes wooden crates reinforced with plastic film, clearly marked with all necessary shipping labels. The product generates an annual domestic sales revenue of approximately 20 million RMB and is exported to markets across Southeast Asia and Latin America. By choosing our step-down distribution transformers, you are assured of an efficient and stable power distribution experience.
