Abstract: Ducting particularly suited for placement over an existing cable run comprises a tubular duct, for example glass filament wound epoxy duct, the wall of which is slit along the length thereof. Opposed to the slit the wall is weakened e.g. by perforating to form integral hinges upon which the duct may be hinged open for the introduction of the cable therein.

Abstract: A dry well fuseholder for use with electrical apparatus containing a dielectric liquid. The holder has an outer, liquid-tight, tubular shell and a number of components inside the shell abutting coaxially in the following order: an annular fitting adapted for supporting the fuseholder on the apparatus; an insulating tube; an annular fuse terminal; another insulating tube; and an annular fuse terminal closed at one end. Glass fibers bonded together with epoxy resin are wound over the peripheral surface of the fitting-tube assembly to produce the shell. Seals are located between the fittings and shell near the joints of fittings and tubes. These seals are composed of a material which swells on contact with the dielectric liquid. This is a division, of application Ser. No. 680,209, filed Apr. 26, 1976, now U.S. Pat. No. 4,081,778.
