Abstract
Electric fuses having supports for their fusible element or elements which supports are formed of bundles of glass fibers in form of cords, rovings, or the like glass fiber structures made up of fibers which extend but in longitudinal direction, i.e. do not include fibers which extend in transverse direction. The fibers are under considerable stress in longitudinal direction, so as to form a supporting structure of considerable dimensional stability. The terminal elements of the fuse are preferably in the form of terminal plugs and provided with means to control the stress to which the glass fibers are subjected. The latter may be impregnated with chemical compounds that evolve protective and arc-quenching gases under the heat of electric arcs.
