Arc-quenching fuse tubes comprising an elongated tubular body having an inner arc-quenching surface layer which comprises an arc-quenching matrix comprising a fibrous material and an arc-quenching composition. The arc-quenching compositions comprise a cured composition of an aromatic epoxy resin and a linear aliphatic epoxy resin.

Arc-quenching fuse tubes

A fuse assembly for an electrical cutout is provided with capability for rapid arc extinction by a capsule of pressurized insulating gas being located within a fuse tube above the fusible element so that when the fusible element melts and an arc is produced, gas is released from the gas cylinder that quenches and cools the arc and also assists a spring loaded flipper mechanism in expelling a lower conductor from the fuse tube.

Fuse assembly, for a cutout, with accelerated arc extinction

The present invention discloses a modular reactor that increases the inductance per axial length by winding a conductor circumferentially about a central axis in a manner which results in radially extending columns which are sequentially wound in alternating radial order. The modules are constructed to allow them to be combined in either radial or axial juxtaposition and electrically connected either in series or in parallel.
