A method of connecting electrical substation wiring in an electrical substation provides pre-bundled yard cables configured to connect between field devices in the substation and a yard interface connection cabinet. The yard interface connection cabinet has an outside plug bulkhead plate that is accessible from outside of a control house that houses the yard interface connection cabinet. The outside plug bulkhead plate has a plurality of connectors configured to mate with the yard cables. The yard interface connection cabinet further has internal wires extending from an inside plug bulkhead plate and terminating at a terminal block. The connections and wires in the yard interface connection cabinet are tested with the yard cables before installation of the yard interface connection cabinet and yard cables in the substation. The yard cables are connected between the field devices and the outside plug bulkhead plate from outside of the control house.

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.

A guard assembly includes a main body that is sized to fit around insulator bushing equipment and forms an opening, and a plurality of faceplates that are interchangeable to connect to the main body and cover at least a portion of the opening.

A wire harness including: a wire; a wire-side terminal that is electrically connected to the wire; and a terminal block to which the wire-side terminal is attached, wherein: the terminal block includes a holding fitting that holds the wire-side terminal in a state where the wire-side terminal is electrically connected to a contact, the holding fitting includes a plate, and at least one of the wire-side terminal and the holding fitting includes a curved surface that is in contact with the other of the wire-side terminal and the holding fitting in a state where rotation in two directions around two axes that intersect each other is allowed.

Provided are load bearing universal adaptors for connecting electrical cables in a watertight configuration. The mechanical advantage associated with wedges in a tapered cavity ensures that load is appropriately transferred to the walls of the wedge housing. In this manner, a load applied to the electrical cable is at least partially provided to the walls of the system rather than acting to pull the cable out of the adaptor, and the object to which the adaptor is connected, such as a terminal block.

A cable termination system including a power cable sequentially including a first length of exposed outer semiconductive layer, a length of exposed insulating layer and a length of exposed electric conductor, an electric field control element adapted to be arranged around a portion of said power cable, said electric field control element including: first and second longitudinally spaced semiconducting electrodes; a field grading layer longitudinally extending between the first and second semiconducting electrodes and in electric contact therewith; an insulating layer surrounding the semiconducting electrodes and the field grading layer, wherein the first semiconducting electrode is positioned across a first boundary between the first length of exposed outer semiconductive layer and the length of exposed insulating layer, wherein said second semiconducting electrode is electrically connected with said length of exposed electric conductor, a tubular insulating body adapted to house said power cable and said electric field control element.
