An electrical cable splice includes a housing having a channel configured to hold a first signal conductor of a first electrical cable therein. The channel is configured to hold a second signal conductor of a second electrical cable therein in electrical engagement with the first signal conductor such that the first and second signal conductors are electrically interconnected. The second electrical cable has a greater diameter than the first electrical cable. A ground shield external to the housing such that the ground shield extends at least partially around the first and second signal conductors. The ground shield is electrically connected to electrical ground conductors of the first and second electrical cables.

An electric wire is terminated with a wire terminal. The electric wire includes a conductor composed of strands and a sheath. The wire terminal includes a wire barrel portion that composed of a bottom plate, a first side plate extending from one side edge of the bottom plate and a second side plate extending from another side edge of the bottom plate. The wire barrel portion holds the conductor exposed from the sheath to make an electrical connection with the strands. The number of the strands contacting directly with the first side plate gradually changes along a longitudinal direction of the conductor. The number of the strands contacting directly with the second side plate gradually changes along the longitudinal direction inversely with respect to the first side plate.

A top drive service loop cable assembly including a plurality of cabled internal cable components a jacket covering the internal cable components, and a flange connected to the jacket and supporting sat internal cable components. The jacket has an embedded lay line embossed into the cable, aligned with internal cable components.

A method connects an electrical device (10), which has a tubular metal sheath (13) with protruding electrical conductors and contact sections (11, 12) connecting to contact sections (21, 22) of electrical conductors (23, 24) of a connection cable (20) by an insulating element (40, 140) that has receptacles (41, 42, 43, 44, 141, 142, 143, 144).
