Ultra-High Voltage Dielectric Strength Tester

The High-Voltage Cable Outer Sheath Fault Tester is a high-voltage cable outer sheath testing system developed by our company in response to the trend of high-voltage and ultra-high-voltage transmission in the current power system, where single-core cables often experience multiple grounding faults in their outer sheath.At the 35KV_500KV voltage levels, the metal sheath is typically grounded at one end or in segmented cross-connected grounding during installation. If there is a破损 point on the outer sheath, a significant circulating current will occur, which can damage the main insulation of the cable. According to the special grounding method of the super-high-voltage cable sheath, this test system is equipped with a bridge distance measurement section and a step voltage location section.

This set of equipment, by effectively combining its functions, can test for external sheath grounding or leakage current issues in ultra-high-voltage single-core cables, as well as significant hidden dangers. It also handles the testing of main insulation faults in high-voltage cables. The system has no blind spots during testing, excels in locating leakage tracking failures that are not punctured for short cables and cable joints, and meets the requirements for testing external sheath faults in high-voltage cables.
