50kva Single Phase Power Pole Transformer Step Down Electrical Transformers
It can reduce the length of low-voltage distribution lines, reduce line losses, and improve the quality of power supply. The transformer is designed with high efficiency and energy-saving coil core structure. The transformer is characterized by small volume, small infrastructure investment, reduced radius of low-voltage power supply and more than 60% loss of low-voltage line.
