National Grid Large-scale Energy-saving Distribution Transformer Supply Project

This project is a key national grid infrastructure renovation project focusing on urban and rural power distribution system upgrading. Our company provided a full batch of high-performance silicon steel core and amorphous alloy core distribution transformers for the national grid power optimization program. Facing the grid’s strict requirements for low loss, low noise, high stability and long-term operational safety, we delivered customized standardized transformer solutions with strict quality control and on-time mass delivery. The project fully proves our professional manufacturing capability and stable supporting service capacity for large-scale national grid engineering projects.

Project Background

To optimize regional power supply quality, reduce grid operation energy consumption and replace aging power equipment, the local national grid launched a comprehensive power distribution network upgrading project. The grid side put forward extremely strict technical standards: transformers must feature ultra-low no-load loss, strong environmental adaptability, stable all-weather operation and unified standard specifications to meet long-term grid safe power supply requirements.

Meanwhile, the project required short delivery cycle, batch consistency quality and complete test certification documents, which raised high demands on the manufacturer’s production strength and quality system.

Project Introduction

In this cooperation, we supplied multiple sets of 10kV–35kV energy-saving distribution transformers, including conventional silicon steel core transformers and high-efficiency amorphous alloy core transformers, which were widely used in urban residential power supply, industrial park power distribution and outdoor substation supporting scenarios. All products strictly comply with IEC international standards and national grid technical specifications. We completed customized optimization design, batch production, full performance testing and unified packaging delivery within the required cycle. All finished products passed grid official sampling inspection and field acceptance with excellent data.

Our Solution

Firstly, we adopted high-purity oriented silicon steel sheets and high-quality amorphous alloy strips as core raw materials, effectively reducing transformer no-load loss and operating noise, realizing obvious energy-saving effects. Secondly, we applied F-class high-temperature resistant insulation materials and vacuum pressure impregnation technology to improve the transformer’s moisture resistance, corrosion resistance and operational stability, adapting to complex outdoor working environments. Thirdly, we implemented full-process quality inspection including raw material testing, semi-finished product size calibration, magnetic performance testing, insulation testing and finished product type testing to ensure zero defective products in batch delivery. Finally, we provided professional technical documents, installation guidelines and after-sales follow-up service to support the smooth completion of the grid project.

Customer Feedback

“We have cooperated with the factory for many grid renovation projects. Their transformers feature stable performance, ultra-low loss and consistent batch quality, fully meeting national grid engineering standards. The whole production and delivery process is standardized, and the provided technical documents and after-sales support are very professional. All equipment runs stably after grid connection with zero failure. We highly recognize their manufacturing strength and will maintain long-term strategic cooperation.”
