  • Patent number: 8101034
    Abstract: An improved method for imparting excellent long-term dielectric performance to an in-service electrical cable section having a stranded conductor surrounded by a conductor shield encased in a polymeric insulation and having an interstitial void volume in the region of the conductor, the cable section having an average operating temperature T is disclosed. The method comprises injecting a dielectric enhancement fluid composition into the interstitial void volume.

  • Patent number: 7976747
    Abstract: A method for extending the useful life of an in-service electrical cable section having a stranded conductor surrounded by a conductor shield encased in a polymeric insulation jacket and having an interstitial void volume in the region of the conductor, the cable section having an average conductor temperature T. The method comprising (i) continuously introducing a non-condensing exclusion fluid into the interstitial volume, the exclusion fluid comprising at least one non-condensing exclusion component having a solubility in the insulation polymer at least 100 times the corresponding solubility of water, each solubility being determined at temperature T; and (ii) injecting a condensing dielectric enhancement fluid into the interstitial void volume, wherein the dielectric enhancement fluid has a virtual flow rate within the interstitial void volume of less than about 0.1 liter per hour.

  • Patent number: 6416693
    Abstract: Parallel spaced shallow grooves are cut within the surface of an existing reinforced concrete member in the direction of bending and at locations where existing tensile reinforcing is inadequate. A curable polymer adhesive resin, such as an epoxy resin, is inserted into each groove and an elongated fiber reinforcing element, such as a composite rod with continuous carbon fibers, is positioned within each groove, substantially filling the groove, so that the minimum volume adhesive resin surrounds the reinforcing element. The adhesive resin within each groove is formed flush with the surface and allowed to cure to bond each reinforcing element to the concrete defining the groove. The grooves and reinforcing elements extend within the top surface of a concrete slab across a beam or support for the slab, extend within the bottom surface of the slab at least fifty percent of the distance between adjacent supports for the slab, or within a vertical surface of a concrete or masonry wall or column.

  • Patent number: 6248270
    Abstract: A disclosed method of repairing a shed portion of a composite insulator having a core portion, a sheath portion arranged on an outer surface of the core portion, and a plurality of shed portions projected from the sheath portion, includes the steps of, (1) cutting out the shed portion having defects from the sheath portion while leaving the sheath portion, and connecting a new shed portion having the same shape as that of the cut out shed portion to the sheath portion at the cut out portion, or (2) cutting out partly the shed portion having defects, and connecting a repairing member to the cut out portion. Therefore, it is possible to perform the shed portion repairing operation without wasting the normal shed portions.
