Description
Vacuum cast coil dry-type transformers are moisture-proof, suitable for operation in very humid or heavily polluted environments. For this technology, the encapsulation process for high voltage winding ensures optimum insulation and mechanical characteristics, and provides for high reliability during operation.
The transformers have the following characteristics:
Windings have high mechanical strength and less partial discharge.
Epoxy resin and insulating materials used for windings are non-flammable, will not burn from an electric arc, and no toxic gases will be given off when the resin is burned.
Envionmental adaptability with windings that will not absorb moisture and a special anti-rust protective coating that seals the core and frame.
Operates under one-hundred percent relative humidity and other severe ambient conditions.
Ability to switch on the device without pre-drying or long periods of service interruptions.
Excellent short-circuit and lighting impulse strength.
Cooled naturally by air (AN) and forced air cooling (AF) provided as an option to improve overload capacity.
Smaller dimensions, less weight, and space saving.
Oil drainage pits and fire extinguishing devices not required for operation.
Customized Designs:
To meet the needs of each unique application, specialized designs can be developed for our single phase, isolation, rectifier, and grounding transformers. In addition, customized tapping arrangements can also be provided.
