Low Noise Oil-Cooled Distribution Transformer

Kechangelec's S22 1250kVA oil-immersed transformer provides a reliable link in uncompromising medium-voltage power distribution. This equipment, the product of rigorous design and the finest materials, guarantees steady efficiency in manufacture and trade alike, always pushing down the costs of energy in the years to come.

This type of medium-voltage distribution transformer comes with a magnetic core that has been reworked quite a bit, mainly to cut down on both no-load and load losses. In real use, what that translates to is higher efficiency and noticeably less humming noise compared with older designs. The windings are made with copper-good quality copper, not the cheaper stuff-and the oil inside is a refined mineral oil that does a reliable job of carrying heat away while also insulating. The outer tank itself is heavy steel. It's not only solid but also coated with an anti-rust finish, which makes it hold up well in damp air, dusty surroundings, and even when it sits under the sun for long hours.

The S22 1250kVA oil type power transformer utilizes an ONAN (Oil Natural Air Natural) cooling method, relying on natural oil circulation and air convection to maintain optimal operating temperatures. Precision-engineered gaskets prevent oil leakage, and the unit is easy to maintain with accessible inspection points.
