Fire detection for oil filled transformers - NFPA (fire , chad transformer tank fire volume

I am not sure about the reason for a heat/ smoke detector to cover an oil filled transformer. The oil is normally a non combustible (under definition of NFPA) product and transformers under many circumstances blow up at which point smoke detectors would be meaningless. I have never seen a transformer fire but I have seen them blow up.Medium voltage transformers dry-type, oil & power , chad transformer tank fire volumeGround Mounted Distribution Transformer up to 3.15MVA at 36kV. The GMX range is an outdoor range of ground-mounted oil-filled transformers with bushings wall mounted to suit cables from above or below. Rated from 315kVA to 3.15MVA or higher at 11kV and 22kV, GMX transformers are fully compliant with the Minimum Energy Performance Standard (MEPS).PADMOUNT EQUIPMENT LOCATIONS / CLEARANCESmasonry fire barrier wall 3' from the back or s ide of the equipment to the side of the combustible wall (see figures below). Barriers must be at least 9' wide and 15' tall. If there is a combustible overhang on the building, that overhang must be 16' or greater from the bottom of the transformer (10' radial clearance from a 6' high transformer).
