    摘要: A method for rejuvenating a strand-blocked cable having a conductor comprised of a plurality of conductor strands with interstitial volume therebetween blocked by a PIB based mastic, the conductor being surrounded by a polymeric cable insulation. The method comprising installing injection adapters that seal the cable ends of the cable and are usable to inject fluid into the interstitial volume between the conductor strands of the cable; elastically expanding the polymeric cable insulation through the application of pressure to the interstitial volume between the conductor strands of the cable; and injecting at least one injection fluid in which the PIB based mastic is at least partially soluble into the interstitial volume between the conductor strands of the cable. To facilitate elastic deformation of the polymeric cable insulation, the cable may be heated to and maintained at a temperature of T1 above ambient during the injection.

    摘要: A plurality of electric wires of a wire harness have a filler applied to predetermined waterproofing portions thereof. A sheet is wound on a peripheral surface of a bundle of electric wires to which the filler has been applied, and the sheet-wound waterproofing portion is repeatedly pressed from opposite sides. By such pressing, a relative displacement of the electric wires and the filler can be accelerated and the filler can be spread and filled securely in the waterproofing portion.

    摘要: A method for enhancing the dielectric properties of an electrical cable having a central stranded conductor encased in a polymeric insulation. The cable defines an interstitial void space (v.sub.1) between the strands of the conductor. The volume (v.sub.2) of a dielectric enhancement fluid required to be absorbed by the cable to reach a predetermined level of dielectric enhancement is determined. The ratio of (v.sub.1 /v.sub.2) is computed. If the ratio of (v.sub.1 /v.sub.2) is greater than a maximum ratio of 1.4, then a quantity of the dielectric enhancement fluid is diluted with a sufficient quantity of a diluent to produce a mixture of diluent and dielectric enhancement fluid, such that when the volume (v.sub.1) of the mixture is supplied to the cable interior, the cable will have been supplied with a volume (v.sub.3) of the dielectric enhancement fluid within the mixture such that (v.sub.3 /v.sub.2) is less than 1.4. The diluent is substantially insoluble in the polymeric insulation, has a sufficiently low initial viscosity to enable introduction into the cable interior, and is miscible with the dielectric enhancement fluid.
