Arrangement for rendering watertightness at electrical connections on power transformers

Abstract From the Canadian patent

An arrangement for rendering watertightness electrical connections on power transformers of the type which has a reservoir containing an insulating and cooling fluid such as an oil the, electrical connections between inside parts of the transformer and the cable terminals outside are made in the form of conductors which, together with the outside cable terminals are embedded in, a block which is plugged into the transformer housing with a watertight seal placed between it and the transformer. Thus the joint between the two is rendered watertight.
