Transformer Oil Filtration
CHUNG TIN EQUIPMENT SERVICES COMPANY LIMITED provides transformer oil filtration services for medium- and low-voltage substations, factories, industrial parks, and industrial electrical facilities.
The service aims to restore the quality of insulating oil, remove moisture, gases, and impurities, helping transformers operate safely – stably – and extend their service life.
⚡ ROLE OF INSULATING OIL IN TRANSFORMERS
Transformer oil has two main functions:
-
Electrical insulation between energized components
-
Heat dissipation for the transformer core and windings
During long-term operation, the oil may:
-
Absorb moisture
-
Contain dissolved gases and contaminants
-
Experience reduced breakdown voltage
👉 If not treated in time, it can easily cause electrical discharge, serious faults, or transformer fire and explosion.
