    Cable Outer Sheath Fault Locator Set for 10kV-500kV Cables


    Cable Outer Sheath Fault Locator Set can quickly and accurately find hidden dangers such as grounding faults and excessive leakage current of the outer sheath of 10kV-500kV single-core and three-core high-voltage and extra-high-voltage cables. At the same time, it can carry out 5kV-10kV, 1 minute DC withstand voltage test on the outer sheath of high-density polyethylene and polyvinyl chloride cables. It is an essential special instrument for cable equipment maintenance of 10kV-500kV single-core and three-core high-voltage and extra-high-voltage cable operating units, extra-high-voltage cable engineering companies, and various power transmission and transformation engineering companies.

    XHHG521A is designed based on the MURRAY bridge principle and can be used to locate the breakdown points of various wires and cables and the defect points that have no breakdown but low insulation resistance values. The equipment uses an electric voltage regulator and an R-type transformer to form a high-voltage constant current source, and the button operation can increase or decrease the voltage. The no-load voltage is 7500V, the short-circuit current is 100mA, and a high-sensitivity amplifier and galvanometer are used to indicate balance. It forms a balanced bridge with a proportional potentiometer, and the whole is placed at a high potential. The measurement cable is a specially designed two-core high-voltage rubber cable. The four-terminal resistance measurement method is used to avoid errors caused by lead resistance. The entire panel is at low potential. One-touch operation, enter the cable length and automatically calculate the fault distance. The high voltage source and bridge are integrated in a portable protective box. Therefore, the device has high voltage, light weight, easy operation and safe use.


    No load voltage≥7500V
    Short circuit current≥100mA (when adjusting balance, it is recommended to set it at 5~40mA);
    Positioning accuracy±(0.2%·L±1)m
    Weight25kg
    Power supplyAC 220V (±10%), 50Hz±1Hz; 8.4V built-in battery.
