It is mainly used to quickly replace conventional substations and restore power supply in emergency situations. After arriving at the site, it only needs to be simply connected and can be used, dedicated for power protection.1. Through the application of new insulation materials and three-dimensional optimization of the overall structure, advantages such as small size, light weight, and convenient transportation have been ensured; 2. The internal body and other components adopt special six directional rigid positioning, which is suitable for the frequent movement characteristics of substations and improves transportation reliability; 3. High operational reliability, overall product quality superior to the requirements of State Grid standards for ordinary substation transformers.
