Advanced Detection for High-Voltage Cable Maintenance
The Cable Outer Sheath Fault Locator Set is a precision instrument designed to quickly and accurately identify grounding faults and excessive leakage current in 10kV-500kV single-core and three-core high-voltage cable outer sheaths. This essential maintenance tool performs 5kV-10kV DC withstand voltage tests (1 minute duration) on HDPE and PVC cable sheaths.
Key Features
Detects faults in 10kV-500kV cable outer sheaths
Performs 5kV-10kV DC withstand voltage tests
Based on MURRAY bridge principle for precise fault location
Identifies both breakdown points and low insulation resistance defects
Essential for power transmission and cable maintenance operations

Operation Principle
The XHHG521A model utilizes an electric voltage regulator and R-type transformer to create a high-voltage constant current source. Featuring one-touch operation, it automatically calculates fault distance when cable length is entered. The integrated high-voltage source and bridge are housed in a portable protective box, combining high voltage capability with operational safety.
Applications
This specialized instrument is indispensable for maintenance teams at high-voltage cable operating units (10kV-500kV), extra-high-voltage cable engineering companies, and power transmission/transformation engineering firms.
