Totally Enclosed Non-Ventilated Transformers
Low Voltage Distribution transformers
Totally Enclosed Non-Ventilated (TENV) transformers are highly suitable for adverse atmospheric conditions. They are built to restrict unintentional circulation of external air through the enclosure. TENV are desired in areas where conductive, combustible or corrosive materials like lint, dust or dirt are present. The fully enclosed non-ventilated transformers are available in Al or Cu windings from 15 to 750kVA.
Applications include the food and paper industries, foundry, textile, electrochemical and other industries where the transformers may be exposed to spray or wash down conditions.
