Cable Outer Sheath Fault Locator
Product Introduction
The output voltage of the high-voltage cable outer sheath tester is 10kV and below, fully meeting the cable outer sheath withstand voltage test requirements specified in the Chinese national standard GB50150-2006. This includes interconnection system cable outer sheath acceptance tests, preventive tests, and cable outer sheath fault location. Rapidly and accurately detects potential hazards such as ground faults and excessive leakage currents in 10kV-500kV single-core and three-core high-voltage/extra-high-voltage cable outer sheaths. Additionally, it performs 5kV-10kV, This instrument is essential for cable equipment maintenance by operators of 10kV-500kV single-core and three-core high-voltage/ultra-high-voltage cables, ultra-high-voltage cable engineering companies, and transmission and transformation project contractors.

Prodection details
MOEORW-W9340 Cable Outer Sheath Tester is compatible with 10kV-500kV single-core/three-core high-voltage and extra-high-voltage cables. Its core application scenarios are as follows:
Engineering Handover Testing: After cable installation, conduct 5kV-10kV/1min DC withstand voltage tests to verify HDPE/PVC outer sheath insulation performance. Compatible with cross-interconnection systems and compliant with GB50150-2006 standards.
Preventive Operation Testing: Periodically inspect outer sheath insulation to detect hazards such as termite damage, water ingress in grounding boxes, and insulation degradation, while monitoring leakage current;
Fault Location and Repair: Rapidly pinpoint outer sheath ground faults using the "step voltage method" for direct-buried cables and the "current method" for tunnel cables, resolving location challenges in deep-buried and complex environments.
Company Qualifications
1)What methods are used to achieve the location function of the MOEORW-W9340 Cable Outer Sheath Tester, and for which cable laying methods are they respectively applicable?
Answer: The locating function of this instrument is achieved through the "step voltage method" and the "current method." The step voltage method is suitable for locating outer sheath faults in direct-buried cables, while the current method is suitable for locating outer sheath faults in tunnel-laid cables.
2)What is the operation method for switching between the locating mode and the withstand voltage mode on the MOEORW-W9340 Cable Outer Sheath Tester?
Answer: The instrument features a dedicated Positioning/Withstand Voltage Function Switch button for one-touch mode switching. A red light indicates the withstand voltage function, while a green light indicates the positioning function, ensuring convenient and efficient operation.
3)What core operational safety protocols must be followed when using the MOEORW-W9340 Cable Outer Sheath Tester?
Answer: Core safety protocols include: 1. Never power on the instrument while connecting or disconnecting cables; 2. Do not touch high-voltage leads or the cable under test during operation; 3. Before starting the instrument, fully turn the voltage adjustment knob counterclockwise (zeroing) to enable startup; 4. Ensure the instrument is reliably grounded; 5. After testing, perform high-voltage discharge on the faulty cable before removing test leads.
