I would like to get your opinion on a suitable fire protection for the Oil immersed Transformer (6.6kv/0.433) that is located inside a 40 feet container cabin. I am a bit reluctant to propose an Inergen Fire Suppression system for this room and considering detectors only.


Is there any other alternative system like those with a ball type of extinguishing system but I am not sure there is any local AHJ approval for that type of device.


Our Universal Building By Law (UBBL) states all transformers are hazardous and requires a gas suppression system.

Appreciate your confirmation on the above.


Best regards,
