An electrical conductor assembly for a rotor blade includes a substrate and at least one electrical conductor. The substrate includes an inboard end portion and an outboard end portion. The at least one electrical conductor is attached to the substrate and extends between the inboard end portion and the outboard end portion. The at least one electrical conductor is configured to transmit electricity along a length of the rotor blade. The inboard end portion and the outboard end portion are structured such that when the electrical conductor assembly is installed within the rotor blade, the inboard end portion is securable relative to the rotor blade and the outboard end portion is movable relative to the rotor blade.

Provided are devices, methods and systems. A cover system may include a unitary cold shrinkable, tubular, elastomeric cover sleeve defining a cover sleeve through passage that is configured to receive the electrical cable. The cover sleeve may include a first type of stress control element and a second type of stress control element that is different from the first type of stress control element. A holdout maintains the cover sleeve in an expanded state in which the cover sleeve is elastically expanded and when removed, permits the cover sleeve to radially contract to a contracted state about the electrical cable. The first type of stress control element includes a geometric stress cone that includes an electrically conductive and/or semiconductive portion that is configured to conductively engage a semiconductor layer of the electrical cable. The second type of stress control element includes a high-K stress relief element.

Problem: To provide a covering processing tool and a covering processing method that can improve an operation efficiency of covering a cable connection portion. Solution: A covering processing tool is a covering processing tool that performs a covering process of a cable connection portion and is provided with a first tubular unit extending in an axial direction, a second to bular unit disposed so as to surround the first tubular unit on an outer peripheral side, and a third tubular unit disposed so as to surround the first tubular unit on the outer peripheral side. The second tubular unit is installed on the first tubular unit so when extracting a first diameter expansion holding member of the first tubular unit, by supporting the second tubular unit from an outer peripher al side, relative movement in an axial direction and a circumferential direction of the first tubular unit relative to the second tubular unit is suppressed.

A cable neutral wires connector for connecting neutral wires of a cable, the cable having a cable longitudinal axis, includes a connector body, a plurality of neutral wire ports, and at least one securing mechanism. The neutral wire ports are defined in the connector body. The neutral wire ports are each configured to receive at least one of the neutral wires therethrough. The at least one securing mechanism is configured to secure the neutral wires in the connector body. The connector body is configured to be mounted on the cable such that the neutral wire ports are circumferentially distributed about the cable longitudinal axis.

A tool system for mounting an elastic sleeve includes a holdout tube supporting the elastic sleeve prior to and during mounting, the holdout tube having a longitudinal axis, an interface element movable along the longitudinal axis and transferring pressure onto the elastic sleeve to push the elastic sleeve off the holdout tube during mounting, and an actuation lever engaging the holdout tube at a fulcrum region of the actuation lever. The actuation lever has a pair of load arms partly encompassing the holdout tube. A load region is arranged at a peripheral end of each of the load arms. The actuation lever actuates the interface element by pressing the load regions of the actuation lever against the interface element.

An assembly for covering at least a portion of a cable, such as an electric cable, comprises an elastomeric tube and a hybrid support core structure. The hybrid core structure includes a central core structure formed from a spirally wound separable ribbon that supports a central portion of the elastomeric tube in a radially expanded state, and first and second solid end core structures that support first and second end portions of the elastomeric tube in a radially expanded state. Each solid end core structure has a film disposed on at least an inner surface thereof having a coefficient of friction less than or equal to 0.05.

A pre-expanded cover assembly unit for covering an electrical connection between first and second cables includes a cover assembly in a folded state including an elastomeric outer sleeve defining a cable passage to receive the electrical connection. The outer sleeve includes an intermediate section and first and second outer sections. The first outer section is folded at a first annular fold and is on the intermediate section and/or the second outer section. The cover assembly includes a first retention layer between the intermediate section and the first outer section. The cover assembly includes a first friction reducing layer between the first retention layer and the first outer section. The cover assembly unit includes a removable holdout mounted within the outer sleeve. The cover assembly is movable from a folded state to an unfolded state by sliding the first outer section in a first axial direction away from the intermediate section.
