锡林浩特SMD underground transformer

Underground transformer is a compact power distribution facility that installs transformers, protective fuses, etc. in the same oil tank. Underground transformer is a transformer that can be installed in a pit and can meet the needs of single-ring network high-voltage power supply. It is suitable for long-distance, small-load high-voltage output systems such as roads, bridges, airports, tunnels, and scenic spots.
