GB/T 9326.1-2008 Oil-filled,paper or polypropylene paper laminate insulated,metal-sheathed cables and accessories for alternating voltages up to and including 500 kV—Part 1:Test

Scope

This part of GB/T 9326 is applicable to the testing of radial electric fields, paper or polypropylene composite paper insulated metal sheathed oil-filled cables and their accessories. When the cables and their accessories are in operation, the minimum static pressure is 20 kPa to 300 kPa, and the maximum static pressure is not more than 800 kPa. The minimum instantaneous pressure is not less than 20 kPa (the pressure mentioned here is gauge pressure, which is higher than atmospheric pressure). Except for clauses 3.2, 4.5 and 5.2, which can be appropriately modified by agreement between the buyer and the manufacturer, this part is also applicable to cables and accessories with a maximum static pressure exceeding 800 kPa. These tests are applicable to cables and accessories used in systems with a nominal phase-to-phase voltage not exceeding 500 kV. For long-length cables, this part is applicable upon agreement between the buyer and the manufacturer.
