An electrical raft assembly 600 for a gas turbine engine comprising electrical raft 200 having multiple electrical conductors 252 embedded in a rigid material is provided. The electrical assembly has an electrically conductive screen layer 260. The electrically conductive screen layer 260 provides electromagnetic protection to the electrical conductors 252. The electrically conductive screen layer is electrically connected to a mounting fixture 700, which in turn may be electrically connected to a mounting structure 40 of an apparatus on which the electrical assembly may be mounted. The electrical raft 200 is used to transport electrical signals (which may be, for example power and/or control signals) around the gas turbine engine. The electrically conductive screen layer may be partially embedded in the rigid material. An electrical unit 300 may be mounted on the electrical raft wherein the electrical unit has a casing at least part of which is electrically conductive.
