摘要

The impregnation system has a vessel (1) with a cover (1.1) into which is immersed a rotor, motor or electrical transformer. The vessel is coupled to a supply tank (2) by a pair of pipes (7,8) that are fitted with isolating valves (4.1- 4.3) . Pumps are provided (5) to control the circulation of the impregnation liquid.
