An insulated electric wire includes a conductor in which elemental wires made of a metal material are twisted together; and an insulation covering that covers an outer circumference of the conductor. The insulated electric wire includes: an exposed portion in which the insulation covering is removed from the outer circumference of the conductor; a covered portion in which the insulation covering covers the outer circumference of the conductor, the exposed portion and the covered portion being provided adjacent to each other in a longitudinal axis direction; and a water-stopping portion in which gaps between the elemental wires in the exposed portion are filled with a water-stopping agent. In an area enclosed by the surface of the water-stopping agent, the surface of the elemental wires is in contact with only the water-stopping agent or another elemental wire.

Provided are methods for extending the life of in-service electrical cable having polymeric insulation, comprising injecting a dielectric enhancement fluid composition into the cable, wherein the composition comprises: (a) one or more organoalkoxysilane functional additives (voltage stabilizer-based, hindered amine light stabilizer (HALS)-based, and/or UV absorber-based); and (b) a catalyst suitable to catalyze hydrolysis and condensation of (a), the injected composition providing for rapid initial permeation of (a) into the insulation, and extended retention of subsequent condensation products of (a) in the insulation. Additionally provided are innovative silyl functional ferrocenes (e.g., containing a ferrocene moiety and a silyl function hydrolysable to silanol) having utility as functional voltage stabilizing additives in the methods.

An insulated electric wire includes a conductor comprising twisted elemental wires and an insulation covering. The insulated electric wire includes an exposed portion in which the insulation covering is removed from the outer surface of the conductor, and a covered portion in which the insulation covering covers the outer surface of the conductor. The exposed portion and the covered portion are adjacent with each other along a longitudinal axis of the insulated electric wire. A density of the conductive material per unit length is higher in the exposed portion than in the covered portion. The elemental wires are twisted in both the exposed portion and the covered portion including an area that is positioned away from the exposed portion by at least a distance corresponding to a length of the exposed portion. Gaps between the elemental wires of the exposed portion are filled with a sealant.
