With the full deployment of urban network transformation, many power supply bureaus, construction parties, and design units are encountering 110kV XLPE cables for the first time. Due to time constraints and insufficient experience, many cables fail to pass the withstand voltage test (10kV/1min).
Most outer sheaths are made of HDPE material, which passes factory DC 25kV/5min withstand voltage tests with leakage currents as low as tens of μA. Post-installation defects are typically caused by external damage during laying, while operational defects include termite damage, water ingress in grounding boxes, moisture penetration, and insulation resistance reduction.
Our high-voltage cable outer sheath fault detector with 10kV output meets Chinese national standard GB50150-2006 requirements, performing both withstand voltage tests and fault location for cable outer sheaths in cross-interconnect systems. It quickly identifies hidden dangers in 10kV-500kV single-core and three-core high-voltage cables.
This equipment is purpose-built for B2B clients in the power infrastructure sector:
Q1: What voltage range does this cable sheath fault locator support?
The unit provides adjustable square wave output from 0 to 10kV, suitable for testing cable outer sheaths in 10kV to 500kV high-voltage cable systems per GB50150-2006 standards.
Q2: Can this device test both single-core and three-core HV cables?
Yes, it is designed for comprehensive fault detection on both single-core and three-core high-voltage cables across cross-interconnect configurations.
Q3: What safety protection mechanisms are built into the locator?
The locator features over-current, overvoltage, and overheating automatic protection, zero-start safety interlock, and a unique self-discharge design that automatically zeros the HV output when power is cut off.
Q4: How does the self-discharge function enhance operator safety?
When the high-voltage output is interrupted or switched off, the internal discharge circuit automatically drains residual voltage to zero, eliminating the risk of accidental during handling.
Q5: What types of cable sheath faults can this equipment detect?
It identifies external mechanical damage, termite damage, water ingress in grounding boxes, moisture penetration, insulation resistance degradation, and pinpoint fault locations along the cable sheath.
Q6: Is this equipment compliant with international testing standards?
It meets Chinese national standard GB50150-2006 for electrical equipment commissioning tests. For other regional standards (IEC, IEEE), please contact our technical team for cross-reference guidance.
Q7: Can the output frequency be adjusted for different testing scenarios?
Yes, the output frequency is adjustable from 0.2Hz to 5Hz, allowing operators to optimize the signal for different cable lengths, soil conditions, and fault characteristics.
Q8: What is the minimum order quantity and typical delivery time?
The minimum order quantity is 1 unit. Shipping Timeis 5-8 working days, with wooden packaging for secure international shipping. Larger orders may qualify for volume pricing.
Q9: Is on-site training or installation support available?
We provide comprehensive user manuals in English and offer remote technical support. On-site commissioning and operator training can be arranged for bulk orders or long-term partnership agreements.
Q10: What after-sales warranty and maintenance services do you provide?
All units come with a standard warranty. We maintain a ready stock of critical spare parts and offer rapid-response technical support via email and remote diagnostics. Extended warranty packages are available upon request.
