WHAT WE PROTECT

We offer main tank protection for oil-filled transformers rated at 5 MVA and above. As the NFPA 850 recommends, our systems are designed to depressurize the transformer with a few milliseconds after the occurrence of an electrical fault

The OLTC uses oil as an insulator. OTLC explosions are numerous in demanding environments such as T&D substations, oil refineries, and steel plants

TRANSFORMER HOUSING

 

 

Oil-filled cable boxes are also susceptible to internal faults and ruptures

 

 

Bushing faults are the most common reason for transformer fires.
