Abstract: A cable jacket for a conductor is disclosed having a flame-retardant insulation and a gas-permeable, heat-resistant outer casing. The flame-retardant insulation is positioned over the conductor so as to at least partially surround the conductor. The gas-permeable, heat-resistant outer casing surrounds the flame-retardant insulation.

Abstract: The present invention provides a high voltage connector arrangement comprising an elongate electrically insulated module, which may be an insulated and screened surge arrester module, and an insulated connector for connecting the module to electrical equipment, which may be switchgear. The arrangement may be such that components of the module are protected from excess current flow therethrough, or the electrical field at the connector end of the conductive layer screen of the module is reduced. In an embodiment, the arrangement can achieve both of these results. The protection of the module is achieved by placing an electrode of the module within an insulated, and advantageously screened, arm of the connector adjacent the end of the conductive layer screen of the module. The electrode may comprise the electrode at one end of the module or may be spaced therefrom, for example by a component of the module.
