In an assembly comprising an electrically conducting bar, lower and upper electrically insulating films covering opposed faces of the conducting bar, and an electrically insulating member bonded to the upper insulating film, the insulating member protruding on the exposed face of the insulating film so as to prevent propagation of electric arcs by tracking on said exposed face, the insulating member is bonded to the insulating film with a heat-sealable coating.
