    Abstract - (Show below) - (Hide below)

    Describes tests and requirements for radial-field impregnated-paper-insulated cables and accessories in which, during normal operation, a gas pressure exceeding 1.2 MPa (12 bar) gauge is applied internally, i.e. with the gas in direct contact with the insulation.

    Scope - (Show below) - (Hide below)

    This British Standard specifies tests and requirements for radial-field impregnated-paper-insulated cables and accessories in which, during normal operation, a gas pressure exceeding 1.2 MPa (12 bar) gauge is applied internally, i.e. with the gas in direct contact with the insulation.

    It also specifies tests for cables and accessories intended for use in systems with a nominal voltage not exceeding 275 kV between phases.
