Thermoplastic sealed-sheath covering upon electrical bus-bar conductors

Abstract

Abstract An improved and relatively inexpensive electrical conductor, such as a bus-bar, or feeder conductor, of aluminum or copper, for example, is provided with a thermoplastic elongated tubular sheath, or sheath tubing, such as polyvinyl chloride heatreactive tubing of resinous material, having the ends of the sheath, or tubing, sealed, in a water-tight fashion to the busbar by a thermoplastic resinous tape material. In one method of the invention, the resinous tape may be wound adjacent the outer ends of the bus-bar at spaced areas thereon, and the thermoplastic tubing subsequently pulled, as a second operation, upon the bus-bar and heat shrunk into place over the aforesaid spaced taped areas. Another alternate method for sealing the thermoplastic sheath tubing to the bus-bar, is to heat-shrink the thermoplastic insulating tubing, or ''''boot'''' upon the bus-bar after pulling it into place, scalp excess tubing to a specified dimension upon the bus-bar, and then band or tape each of the scalped ends of the tubing, or ''''boot'''' with a suitable thermoplastic resinous tape material, such, for example, as polyvinyl chloride adhesive tape.
