Abstract
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.
Claims16
Electrical supply bar assembly comprising:
- an electrically conducting bar,
- a lower electrically insulating films and an upper electrically insulating film, respectively covering opposed faces of the conducting bar, and
- an electrically insulating member bonded to the upper insulating film opposite to the conducting bar, the insulating member protruding on the exposed face of the upper insulating film so as to prevent propagation of electric arcs by tracking on said exposed face,
- wherein the insulating member is bonded to the insulating film with a heat-sealable coating.
Electrical supply bar assembly according to claim 6, wherein the spacer is bonded to each of the upper insulating film and the insulating member with a heat-sealable coating.
Method of producing an electrical supply bar assembly comprising the steps of:
- bonding upper and lower insulating films over opposed faces of an electrically conducting bar, and
- bonding an electrically insulating member on the upper insulating film, such that the insulating member protrudes on an exposed face of the upper insulating film so as to prevent propagation of electric arcs by tracking along said exposed face,
- wherein the step of bonding the upper insulating film to the insulating member comprises the steps of providing a heat-sealable coating between the upper insulating film and the insulating member and activating said heat-sealable coating by heating.
