DESCRIPTION
BS 7923:2004
This standard BS 7923:2004 Electric cables. Internal gas-pressure cables and accessories for alternating voltages up to and including 275 kV (Um = 300 kV). Requirements and test methods is classified in these ICS categories:
- 29.060.20 Cables
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.
