Power & Substation Transformers

Substation Transformers

Liquid Filled - GE Liquid-filled transformers are designed for industrial and commercial applications such as chemical, cement, manufacturing plants, paper or steel mills, schools, hospitals, office buildings, etc. Liquid-filled units use sealed-tank construction that effectively contains the windings and most live parts in a controlled atmosphere. When specified, less-flammable liquid-filled units may be installed indoors.

Ventilated Dry-Type - GE ventilated dry-type transformers are designed for indoor or outdoor applications in schools, hospitals, industrial plants, commercial buildings and anywhere that safe and dependable power are important considerations.

WaveCast 724 Cast Coil - Proven technology, application flexibility, lower installation cost, operating efficiency and environmental acceptability are hallmarks of the new GE WaveCast 724TM Cast Coil Transformer. WaveCast 724's are designed for indoor or outdoor applications in the most demanding and diverse environments. Advanced design of the winding assembly establishes superior performance to meet exacting customer needs.
