Abstract :
The paper describes accelerated aging studies on sealed tube specimens and functional life tests on distribution transformers which contained SF-97(50) silicone liquid and solid insulation normally used in oil-filled transformers. The results indicate that silicone oil is compatible with the solid insulation tested, and that the aging characteristics of the silicone system are as good as those of a 65°C mineral oil-filled system.
