Scope

This part of GB/T 22078 specifies the test methods and requirements for XLPE insulated cable systems, cables and their accessories for fixed installation with a rated voltage of 500kV (Um=550kV). This test requirement applies to single-core cables and their accessories under normal installation and operating conditions, but not to special cables and their accessories, such as submarine cables. For special cables it may be necessary to modify the tests of this standard or it may be necessary to refer to special test conditions. This section does not include transition joints for XLPE insulated power cables and paper insulated cables.
