The iron core of S11-M series low loss energy-saving transformer produced by our company adopts laminated structure.
This product is based on fully absorbing the advanced technology and process of domestic oil immersed transformer, combined with the technical level of our company, putting the reliability of the product in the first place, at the same time, the no-load loss and no-load current of the product are greatly reduced.
Advantages of a three-phase oil-immersed transformer S11-315KVA
-The core of silicon steel is made of 0.18 ~ 0.3mm orientation silicon steel sheet stacked by punching and shearing, which has good stability.
-The coil is made of pure copper. The acetal enamelled wire is used for high voltage and oxygen-free copper conductor or copper foil for low voltage to improve the short-circuit resistance.
-The Dyn11 connection symbol is used to avoid the influence of higher harmonics. It provides high resistance against uncompensated load and improves the quality of power supply.
-Vacuum oiling is adopted by the transformer to remove bubbles in the core and ensure stable insulating property.
