Distribution transformers in this size range are used to step down three-phase medium voltage to low voltage for power distribution, mainly in metropolitan areas (public buildings, offices, distribution substations) and for industrial applications. Dry type transformers are ideal for these applications because they can be located close to the power utilization point which allows optimal system design minimizing low voltage high current circuits with the corresponding savings in losses and low voltage connections. Dry type transformers are environmentally safe, provide excellent mechanical and short circuit strength, have no liquids to leak, offer no danger of fire or explosion and are suitable for indoor and outdoor applications.
ABB manufactures dry type transformers with different technologies (vacuum cast coil, RESIBLOC® and open wound) according to the highest quality standards and in ISO 9001 and ISO 14001 certified factories.
