Remanufacturing Services

Remanufacturing Services up to 500kV / 1000+MVA / 1550 kV BIL

Remanufacturing consists of engineering and upgrading the unit to meet the latest industry standards with the application of contemporary design techniques and performance testing that typically was not available when older transformers were originally manufactured. With more than 100 years of experience repairing, rebuilding, and upgrading transformers, GE is a leading supplier of remanufacturing services for both shell-form and core-form transformers.

Features & Benefits

Transformer remanufacturing offers utility plan operators a reliable, cost-effective alternative to purchasing new units, with much shorter lead-time. GE's remanufactured transformers meet all ANSI design standards established for new units.
