摘要： A method for making splices in high voltage electrical cable and particularly for replacing relatively short sections of previously removed, original insulation. Ends of the original insulation adjoining the section are tapered and fresh insulating material is placed over the section and heated to fluidize it. Pressure is applied to intimately combine the original cable insulation and the newly added splice insulation to thereby effect an interfacing of the original and newly added insulating material. The new insulating material is placed inside the cavity of a mold which includes small apertures communicating the cavity with the exterior and being spaced over the length of the cavity. The fresh insulating material is pressurized by forcing additional material into the cavity to thereby vent entrapped air through the apertures to the exterior. Some of the apertures are selectively opened and closed to effect the venting while propagating the insulating material and the applied pressure throughout the cavity.

摘要： Crimped paper insulation is applied linearly and continuously to a moving linear electrical conductor without bonding the paper insulation directly to the conductor. The paper insulation is formed with a width exceeding the cross sectional perimeter of the conductor and an adhesive is applied only to longitudinal tab portions formed by the extra width. Progressive rollers fold the paper insulation over the conductor so that the extra width contacts another portion of the insulation but does not contact the conductor itself.

摘要： This disclosure describes process and apparatus for continuous insulating of wires in which sheet material drawn from a roll is pleated and the wires are introduced into the pleats. The pleat envelopes are severed and each assembly of wire and pleat is closed and polished. Advantageously, the sheet material is preselected for specific dielectric and structural characteristics. The sheets may also be precoated with adhesive, and also pre-color coded. The process is capable of high speed operation and produces a highly reliable product without creating air or water pollutants.

摘要： A paper-insulated conductor for communication cables in which layers of insulating paper surrounding the conductor are bonded to each other or the insulating paper is bonded to the conductor by a bonding agent so that the insulated conductor can be inserted into an insertion connector without becoming loose, jointing work with a jointing tool can easily be carried out, and any short circuit will not occur between the conductors within the cable. The insulated conductor has excellent electrical properties in spite of the use of the bonding agent.

摘要： A COMMUNICATIONS CABLE SHEATH IS PROVIDED WITH A SEALED METALLIC BARRIER TO PREVENT MOISTURE DIFFUSION INTO TRANSMISSION COMPONENTS OF THE CABLE. THE BARRIER IS FORMED OF A LONGITUDINALLY APPLIED METALLIC STRIP IN WHICH A RESULTANT OVERLAPPED SEAM IS SEALED WITH AN ACRYLIC ACID-ETHYLENE COPOLYMER THAT HAS BEEN INSERTED INTO THE SEAM, IN TAPE FORM AND SUBSEQUENTLY HEATED BY THE EXTRUSION OF A THERMOPLASTIC SHEATH OVER THE METALLIC STRIP OR, IN THE ALTERNATIVE, IS HEATED BY PASSING THE FORMED METALLIC STRIP AND THE ASSOCIATED TRANSMISSION COMPONENTS THROUGH AN INDUCTION TYPE OR OTHER APPROPRIATE HEATING DEVICE. AN ALTERNATE EMBODIMENT INVOLVES A CABLE SHEATH IN WHICH THE COPOLYMER IS APPLIED AS A PRECOATING ON THE

INSIDE SURFACE OF THE METALLIC STRIP, HEAT TRANSFER FROM THE THERMOPLASTIC EXTRUSION OPERATION TO THE OVERLAPPED SEAM CAN TAKE PLACE WITHOUT ENCOUNTERING AN INSULATING BARRIER OF THE COPOLYMER. THE LATTER EMBODIMENT CAN BE PRACTICED WITH VIRTUALLY NO CHANGE TO CONVENTIONAL CABLE SHEATHING EQUIPMENT AND APPARTUS.
