Ssangyong Electric’s ground-mounted transformer is 15-30% smaller than other ground-mounted transformers and fit for downtown or cultural heritage areas. It is safe as no cable or electrically charged part is exposed. A fuse, which shuts off the circuit in case of an accident inside or outside the transformer to protect itself and the power line, is built inside our transformer, which is suitable to ensure better aesthetics for the urban environment. It is installed in the underground distribution system, which brings an overhead power line under the ground. As a safeguard is embedded in this transformer and its external power connector is fully insulated, it does not require an additional transformer facility. This transformer features exceptional safety and assimilation with its surrounding environments.
