Smart Control for Modern Grids

 

This solid state distribution transformer is manufactured by Jiangxi Yihong Electric Power Technology. The high-voltage side is rated at 10kV or 20kV, while the low-voltage side provides 0.4kV AC or 800V DC output. The rated capacity ranges from 500kVA to 2500kVA. The input frequency is 50Hz.

 

This solid state distribution transformer achieves an efficiency of over 98%. The switching frequency ranges from 10kHz to 50kHz. It uses either forced-air cooling or liquid cooling. The protection level is IP20 for indoor applications and IP54 for outdoor applications. The product complies with GB/T 37408 and IEC 62895 standards.

 

This model performs voltage conversion and regulation, reactive power compensation, power quality control, and fault current limiting. It is suitable for smart grid systems and data centers.

 

Strong R&D and Full Testing

 

We operate an independent R&D center covering 3,000 square meters. Our team focuses on smart power systems and renewable energy integration.

 

Each solid state distribution transformer undergoes three rounds of quality inspection before shipment, followed by a 100% final inspection prior to packaging. Third-party inspection is also available upon request.

 

We provide a one-year warranty. In case of shipping damage, we assist customers in filing claims with the logistics company. Our after-sales service includes pre-sale design planning, close communication during production, and regular follow-ups via calls or visits. We have five design engineers to help customers select the appropriate model.

 

Easy Order and Global Sales

 

We support OEM and ODM services. Customers may submit technical drawings for customization. The minimum order value is 50,000 RMB. Different capacities can be combined within a single order. Free samples are not provided. Custom samples require 15 working days.

 

Payment terms are 50% deposit and 50% balance before shipment. We accept EXW and FOB terms, with payments available in RMB, USD, or EUR. Discounts are available for large orders.

 

Products are packed using wooden crates and plastic film for export. This solid state distribution transformer is exported to Thailand, Myanmar, Vietnam, Indonesia, Japan, Singapore, and Peru. Last year, overseas sales exceeded 8 million RMB, while domestic sales reached approximately 20 million RMB annually. We welcome your inquiry.
