The transformer core is overlaid with high-quality cold-rolled silicon steel sheets, greatly reducing the no-load loss and no-load current. In order to ensure the compaction of iron core and reduce the noise, we bind the core.
High and low voltage windings are made of oxygen-free copper. 500kvA low-voltage windings and below have a double-layer cylinder structure, while 630kvA and below have a double-helix or four-helix structure. High-voltage windings have a multi-layer cylinder structure. This transformer is fully sealed. It has a lower noise and a longer lifetime. Our product is free from lifting and maintenance. Compared with S11, S14 is more energy-saving, whose no-load loss declines by 30 percent.
