摘要： An electrical cable device such as a heating cable includes a braidless ground return layer surrounding an inner jacket. The ground return layer is formed by a conductive polymer and a ground return wire connected to the conductive polymer. The polymer may be made suitably conductive for ground fault detection by addition of a particulate conductive filler such as carbon black, carbon fibers, or a blend thereof.

摘要： A three-terminal device (1, 21, 31) which can operate as an electrical switch, controlled by a third terminal (3, 24, 36/36A) that controls switching the device (1, 21, 31) from a closed circuit (conducting) state to an open circuit (insulating) state. Polymer and/or ceramic materials are loaded with different conductive materials, forming a device (1, 21, 31) having various electrical conductivities depending on local temperature. In preferred embodiments, the device (1, 21, 31) exhibits a non-linear increase or decrease in resistance versus temperature. Various embodiments of the three-terminal devices (1, 21, 31) are disclosed. The third terminal (3, 24, 36/36A) may be a non-electrically conductive biasing element such as a thermal transfer rod or tube containing a variable temperature fluid.

The heater includes an elongate heating member; an insulating jacket which encloses the heating member; a first electrically conductive member which surrounds the insulating jacket; a separating and insulating member which surrounds the first conductive member; and a second electrically conductive member which surrounds the first conductive member and is separated and insulated therefrom by the separating member. The method includes the step of testing the electrical relationship between the first and second electrically conductive members.
