3-phase transformers



Capsulated three-phase non short circuit proof transformer with power range up to 630 kVA. Standard types supplied with separate primary and secondary windings. This generates "a new system" in which any earth faults are eliminated. Steel plate enclosure, degree of protection IP23.This is an ideal design for transforming voltage up or down or for installations which require a galvanic partition between the primary and secondary voltage. Protects installations and equipment by generating "a new system" in which any earth faults are eliminated. E.g. electric motor, compressor, cooling plants, automatic washing machines, and to uphold IT or TN-S systems. Custom designed types with other voltages , frequencies, electrostatic shield between primary and secondary, regulations, tappings, transport wheels or other features are available upon request.
