In order to test the influence of different shielding materials against the water tree-resistant ability of water tree cable, the performance test method and evaluation procedure of water-resistant tree shielding material performance were established. Two different cable shielding materials were used in the same manufacturer to produce cross-linking of the same shielding structure.
Polyethylene power cable, and made into a 30-segment cable sample. Under the same test conditions, 14 d load cycle, 120 d accelerated aging, 180 d accelerated aging and 360 d accelerated aging, and then the original test before aging A total of five cable samples with different aging conditions were subjected to power frequency step-by-step breakdown, and the power frequency breakdown characteristics of .
XLPE power cables composed of different shielding materials were tested. The test results show that the domestic common shielding materials The power-frequency breakdown characteristics of the manufactured power cable are significantly different from the power-frequency breakdown characteristics of the.
Power cable manufactured by the imported water-resistant tree cable shielding material. The XLPE power cable manufactured by the imported water-resistant tree cable shielding material is accelerated by 360 d. Good power frequency breakdown characteristics after aging tes.
