Application Summary AI generated
GB/T 7971-2007 specifies the requirements for semiconducting electric cable paper, which is used as a conductive shielding layer in high-voltage power cables to prevent partial discharge and ensure uniform electric field distribution. It is applied in the manufacturing of oil-impregnated paper-insulated cables and other power transmission products where controlled electrical conductivity is needed. This standard defines technical parameters such as resistivity, thickness, and mechanical properties for quality control in cable production and testing.
