ZGS11-Z. G-type photovoltaic power generation box transformer is the special electrical equipment which integrates the boosting transformer, high and low voltage switchgear, communication device and corresponding auxiliary support equipment. It's the essential support equipment of photovoltaic power generation systems which outputs power upward through 35kV (or 10kV) after boosting the 0.315kV (or 0.48kV) generated by photovoltaic inverter to 35kV(or 10kV).
