    Abstract: Voltage sensor (1) for a high- or medium-voltage power-carrying conductor for a power network, such as an inner conductor of a power cable or a cable connector or a bus bar. The voltage sensor has a tubular shape and an axial passageway (40), which can receive the conductor. The voltage sensing device comprises a) a radially-inner electrode (20), operable as a first sensing electrode of a sensing capacitor for sensing the voltage of the power-carrying conductor, b) a radially-outer electrode (30), operable as a second sensing electrode of the sensing capacitor, and c) a solid carrier element (10), at least a first portion of which is arranged between the inner electrode and the outer electrode, the first portion being operable as a dielectric of the sensing capacitor. The sensor can be accommodated in a cable accessory. The carrier element may comprise ceramic material to increase accuracy.

    Abstract: 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.
