Fluid oil, not soluble, intended for the cutting and impregnation of induction nuclei, contactors, circuit breakers and other similar devices. SUPRACO ELECTRIC 40 A is a smooth oil, which has a low freezing point and excellent anti-oxidizing properties. It is insensitive to moisture and avoids gumming and oxidation. Low consumption (50mgs per contactor). Deformations by compaction of induction steel sheets, due to repeated shocks are reduced by its use. SUPRACO ELECTRIC 40 A can be used for degreasing operations and impregnation before assembly. Impregnation of steel sheets, induction nuclei, contactors, circuit breakers, cutting steel sheets with silicon (200 HBrinell).
