Dry distribution transformers in this size range are used to step down three-phase medium voltage to low voltage for power distribution. These transformers are used primarily in metropolitan areas (public buildings, offices, distribution substations) and are also found in industrial applications
Dry type transformers are an ideal solution for applications where the transformers have to be installed near their place of use. Close installation saves on the installation outlay of cabling while at the same time reducing losses in cables and terminals on the low-voltage side.
Dry type transformers are environmentally safe and suitable for indoor and outdoor applications. They provide excellent mechanical and short circuit strength, have no liquids to leak, and offer no danger of fire or explosion.
The transformers can be delivered with or without enclosures for extra added protection against harsh outdoor or indoor environments. They can be used in all types of applications including ground mount, primary and secondary substation units.
ABB manufactures dry type transformers with different technologies including vacuum cast coil, RESIBLOC® and open wound. All are built according to international standards and optimized to the application and power range they are covering.
