A two-part system for electrical stress control includes a conformable stress control material positioned at the shield cut edge of a prepared power cable and a stress control tube over the conformable stress control material. A second region of conformable stress control material is positioned adjacent the cut end of the insulation. Relationships are revealed which relate the permittivity and dimensional parameters of the two components.

A fiber optic, Faraday-effect sensing coil has very low linear and circular birefringence, which remains stable over a wide range of temperatures. The coil is fabricated from a spun fiber having an effective linear beat length of 100 meters or more, and is annealed after being formed into the coil. The coil has improved discrimination for magnetic fields associated with electric current-carrying cables, and may be incorporated into an optical current transducer (OCT), either interferometric or polarimetric.

A connector for communication wire pairs has an insulating body formed with sinuous channels for capturing the insulated wire, U-slot contact elements for making contact with the wires and said contacts having spring elements formed by U-shaped cuts in the periphery of the element for contact with an external circuit to connect the same in series or parallel with said spliced wires.
