Compact Substation Unit

We manufacture this unit in compliance with China's GB/T 40823-2021 standard. This standard came into effect on May 1, 2022. It is based on IEC 62271-212:2016, with additional requirements specific to China. As a result, when you choose this compact substation unit, you receive a fully compliant product without concerns about local regulations.
Our design team integrates high-voltage control, transformer protection, and voltage transformation into a single enclosure. You do not need to purchase or test each component separately. With 9 years of manufacturing experience, we take full responsibility for product quality. Every compact substation unit undergoes complete type testing and factory testing before shipment.

This compact substation unit is well-suited for new energy grid connections and rail transit power supply systems. Its modular design significantly reduces space requirements. You can also provide your technical drawings, and we will customize the unit according to your specifications. Custom samples can be developed within one week.

We also provide a 1-year warranty. If any issue occurs, we will assess the problem and replace the necessary parts. We do not dispute responsibility. You can start with a single unit, allowing you to test the market without large upfront investment.

Many customers ask about lead time and customization capabilities. Here is our answer: the compact substation unit is suitable for both indoor and outdoor installation. The high-voltage range is 3.6 kV to 40.5 kV at 50 Hz. It supports high-voltage switching control, transformer protection, and high-to-low voltage conversion.
Our factory is located in Tianchang, Anhui Province. We source and manufacture all key components in-house. This ensures full quality control throughout the production process. You are not purchasing an assembled product from multiple suppliers-you are receiving a fully integrated, tested, and reliable compact substation unit directly from a dedicated manufacturer.
