It has a three-phase five-column structure and is a new energy-saving product. It has no-load loss reduced over 70% compares with that of S9 transformer and less horizontal leak magnet field. The low voltage coil is the copper foil one in order to increase bearing ability of the transformer. The oil tank is a full-closed corrugated one which can retard ageing of oil and prolong sercive life of the product.
The amorphous alloy distribution transformer has its iron core rolled by amorphous alloy . |
