Abstract
A semi-conductor screen for power cables consists of conductive material dispersed in a polymer matrix and comprises a layer of high longitudinal volume conductivity and a layer in contact with the insulating layer within the cable which restricts the injection of charges into the insulating layer from the screen. A semiconductor screen (3, 5) for a power cable comprises two layers (31, 32; 51, 52), each consisting of conducting material dispersed in a polymer matrix. The first of these layers (31, 51) has a longitudinal volume conductivity of more than 0.1 S/m at 20-90 degrees C. The second layer (32, 52) is designed to be in contact with an electrically insulating layer (4) in the power cable and is such that only a small quantity of space charges can be injected into (4) from the second layer (32, 52), i.e. the quantity of charge which can be injected into (4) from the screen (3, 5) is less than that which can be injected into (4) from the second layer alone, the second layer (32, 52) forming a barrier to the injection of charges into layer (4). An Independent claim is also included for a power cable with a screen as described above.
