Electro Wind Three Phase Transformers
Three Phase Transformers.
Electro Wind's three phase transformers are designed and manufactured to IEC60076 and IEC61558.
Our three phase transformers are double wound isolation transformers for continuous duty, complete with earth screen between the primary and secondary windings.
Electro Wind's 3 phase transformers can be manufactured to meet specific standards.
Three phase transformers are smaller and lighter than single phase transformers and offer comparable power handling capacity along with better operating characteristics.
