A wiring harness assembly includes a plurality of separated conductors formed of an electrically conductive material, a substrate formed of a dielectric material encasing the plurality of separated conductors, a location feature integrally formed with the substrate and an opening defined in the substrate having a predetermined size and shape. A section of the plurality of separated conductors is exposed within the opening. The opening is precisely located relative to the location feature.

A water barrier for encapsulating a cable core has an inner layer of lead-free metal foil having an elastic modulus lower than 210 GPa, an intermediate layer of adhesive material, and an outer layer of a polyethylene-based semi-conducting polymer having an elastic modulus higher than 0.5 GPa. A power cable is providing having such a water barrier.

A technique facilitates construction and operation of a power cable which may be used to deploy an electric submersible pumping system downhole into a wellbore. The power cable is constructed to provide structural support of the electric submersible pumping system while also providing electric power to the electric submersible pumping system when located downhole in the wellbore. The power cable has at least one conductor and a plurality of layers selected and arranged to ensure long-term support and delivery of electrical power in the relatively harsh downhole environment.

A filler and a multicore cable includes a plurality of core portions, which includes a conductor, and a protective layer that surrounds the core portions, the filler being provided between the core portions and the protective layer of the multicore cable, the filler being characterized by including: frame portions including a first frame portion and a second frame portion, which are rotated by predetermined angles towards both sides about the center portion thereof and then incised; and a support portion provided between the frame portions so as to connect the frame portions to each other.

A shielded electrical cable includes at least two spaced-apart conductors extending side-by-side along a longitudinal cable direction. An insulation electrically insulates the conductors from each other. A cable shield, together with the conductors, extends along the longitudinal cable direction and annularly surrounds the conductors, as seen in cross section. An electrical device is disposed between the conductors and the cable shield. The electrical device is surrounded by the cable shield and disposed on the conductors such that the electrical device is in electrical contact with each of the conductors.
