Products Description
630 kVA Transformer Details
The 630kVA dry type step up power transformer is designed to operate at a frequency of 50Hz or 60Hz and consists of a primary winding, a secondary winding, and a core. The primary winding is connected to a low voltage power source, while the secondary winding is connected to a high voltage output. The core is made up of laminated magnetic sheets that help to increase the efficiency of the transformer.
These transformers are widely used in various applications, including renewable energy systems, power plants, and industrial processes. They are also used in commercial and residential buildings to power high voltage equipment such as air conditioning systems and elevator motors.
