ABSTRACT OF THE DISCLOSURE The present invention concerns improvements in the use of polyester materials in arc quenching applic- ations, particularly in the cutout fuse tube industry. In one embodiment of the present invention a fuse tube is disclosed as comprising a laminate two-layered structure including as its inner layer, (or liner), a heat-treated polyester filament winding supported in a cured cyclo-aliphatic epoxy resin matrix. The outer layer includes wound glass filaments supported within a cured epoxy resin matrix. The heat treatment of the polyester filament substantially improves the mechanical and electrical character of the fuse tube.
