A flat electrical cable for power distribution is designed for undercarpet use and has two side-by-side live and neutral conductors 12,14 formed into a package 15 by insulation 16,18 around them. In a three-phase construction there are four conductors (FIG. 5). A conductive earthing screen 26 forming the sole earthing conductor overlies the package 15 and is of the same width as the package but is not bonded or only lightly bonded to it. An outer insulating layer 28 tightly surrounds the screen 26 and package 24 and holds them together at the edges, as well as providing protection along the cable edge. The layer 28 is formed of strips 30,32 which can be cut away at X to remove the edges 34 when a connection is to be made, the edge of the screen 26 providing a cutting guide. An insulating plate can be slid between the screen 26 and package 24 so that insulation displacement connections can be made from opposed sides of the cable. |
