10 MVA 24.94/4.16KV Transformer Manufacturing Process

What are Dry-Type Transformers?

A dry-type transformer has no moving parts, it is a static device that uses environmentally friendly temperature insulation systems. Traditional liquid-type transformers rely on environmentally taxing materials like oil or fire resistant liquid dielectric. “Dry” refers to the fact the system is cooled through natural ventilation as opposed to using oil, silicone or a liquid to cool coils and the electrical core. This type of transformer is defined as “voltage changing,” which means air is cooled instead of cooling liquid. The case the transformer sits inside is ventilated so air can cool coils.
