CHARACTERISTICS OF SILICONE INSULATING OIL FOR ROLLING STOCK TRANSFORMER

Japanese National Railways has used a nonflammable oil composed mainly of polychlorinated biphenyl (PCB) in the transformers on cars on the New Tokaido Line (25 kV) and conventional equipment (20 kV). Japanese legislation prohibited use of PCB in July 1972; JNR then sought a non-PCB oil. The new rolling-stock transformer oil is dimethyl silicone oil with viscosity of 25 cST (25 C). Extensive tests have indicated the relation between insulating characteristics and water content, oil temperature, and flammability.
