Cable Outer Sheath Fault Locator Set
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
Technical Specifications
| Parameter | Value |
|---|---|
| No load voltage | ≥7500V |
| Short circuit current | ≥100mA (recommended 5-40mA for balance adjustment) |
| Positioning accuracy | ±(0.2%*L±1)m |
| Weight | 25kg |
| Power supply | AC 220V (±10%), 50Hz±1Hz; 8.4V built-in battery |
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.
