Application Standard Dry Type Ventilated Transformers are cooled by natural circulation of the surrounding air through its windings. For trouble free operation and long life expectancy, the ventilating air must be reasonable free from dust, moisture or other damaging corrosive fumes. For this reason, standard Dry Type ventilated transformers are normally installed in suitable, indoor locations where they are protected from damaging elements. Some specifications require installation of transformers in hazardous surroundings where the above condition can be met. Epoxy Potted Transformers (also referred to as Epoxy Resin Encapsulated) are designed for such conditions. Typical areas of use include: Corrosive environments - Petro-Chemical, steel, pulp and paper industries; Damp conditions - Mines, pump-houses, underground or rooftop service areas; Airborne dust, conductive particles Features Mixture of silica sand resin forming a solid mass completely encloses and protects the core and coil, also significantly reduces audible noise. Windings utilize Class 220oC Insulating rated for 150oC Rise, but designed to operate at 115oC maximum. The transformer's core is solidly grounded.
