S(B)H15 Series Oil-immersed Amorphous Alloy Core Transformer

 Product Description

Amorphous alloy core transformer is a new type of environmental-friendly and energy-saving product. The core is made of wounded amorphous alloy strips, with high magnetic conductivity and low no-load loss. Compared with S11 type distribution transformer,no-load loss is reduced more than 75% .The transformer is full sealed and can be used in all kinds of power distribution places

 
Structural features

• The transformer core is wound core and is three-phase and five-columns style. The cross section is rectangular.
• The coil is rectangular. 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.
