ELECTRICAL OIL SERVICES AT A GLANCE

EXPERTISE, SAFETY AND TECHNOLOGY FOR
INSULATING OIL & TRANSFORMERS

The insulating oil in transformers degrades over time due to operational conditions. This can lead to a drop in performance, failures or damage. To counteract this and to maintain the quality of the insulating oil and the overall transformer, there are various approaches. EOS® provides comprehensive offerings and optimised solutions:
