Abstract:
An insulation insert for preventing electrical contact or arcing between adjacent strands in a stator coil, comprising:a thin base of substantially uniform cross section; a lead-in nose formed in said thin base for guiding said insulation insert into a position between said adjacent strands; two substantially vertical cuts in said thin base above said lead-in nose delineating a center section flanked by two ear portions; and a substantially horizontal crease in each of said ear portions to form opposing wings in said insulation insert; wherein said ear portions include substantially horizontal perforations to facilitate folding of said ear portions to form opposing, wings; wherein said lead-in nose is tapered and sized to enable insertion of said lead-in nose between a first and second adjacent stack of copper strands; and wherein said ear portions are positioned above and wider than said lead-in nose to facilitate insertion of said folded wings at least partially under crimped portions of said copper strands.
