Abstract: An overhead power transmission line formed by stranding at least one outwardly projecting strand at the outermost layer of an overhead power transmission line formed by a plurality of strands. At least the outwardly projecting portion of the outwardly projecting strand is composed of an organic material. The outwardly projecting strand has a projection height H within a range defined as 1.5 mm.ltoreq.H.ltoreq.7.0 mm.

Further, by setting H.ltoreq.7.0 mm, the outwardly projecting strand comprised by an organic material is made easily crushable, so the gripping portions of spacers, dampers, and other parts which have been conventionally used can be used as they are.

Abstract: Insulated wire or cable, the configuration of which is particularly well suited to the orderly coiling of the cable. The cable's insulation is formed in such a manner as to provide interlocking mating surfaces, which surfaces tend to hold the cable in its coiled configuration once so formed.

This splitting may be by a slit or notch partially transecting a cross section of the insulated cable. Pulling the plurality of insulated wires in opposite directions tends to separate the cable into its component insulated wire portions. The stackable cable may be implemented utilizing cables; coaxial cables; solid wires; multiple strand wires, whether straight or twisted; and non-metallic electrical conductors.

Abstract: A pair of tangle resistant electrical test leads, the pair having a first and a second conductor attached to a nonconductive slide fastener, such as a nylon zipper. The first and second conductors are surrounded by loop and hook material. The loop material is attached to the upper side of a first border of the zipper and the hook material is attached to the under side of the second border of the zipper. In a zipped state, the leads remain parallel and of uniform separation, thus eliminating entanglement of the individual leads. When the zipped leads are wrapped about a meter or other test instruments, the loop and hook material secures the wrapped leads upon themselves, in a half-lapped wrapping, thus preventing entanglement of the joined leads. During usage of the electrical test leads, when their full length is not required, the tangle electrical test leads can be unwrapped and unzipped only as much as needed, thereby keeping the leads neater and reducing the likelihood of entanglement.
