The HZDL-GF 0–30kV Underground Cable Fault Locating System is a high-voltage signal source designed for cable fault distance measurement and pinpointing. As a patented product of our company, it meets international advanced standards and features a large discharge capacity, compact size, lightweight construction, and portability.

The internal high-voltage generation unit employs high-frequency boosting for a compact and lightweight design. The high-voltage output utilizes optoelectronic isolation feedback control technology, ensuring safety and reliability. The HZDL-GF is compatible with and used in conjunction with our company's HZ series power cable fault locators and digital multifunction cable fault pinpointers, enabling:

• Pulse current distance measurement
• Multi-pulse distance measurement
• Acoustic-magnetic synchronous pinpointing

• Resists high heat, humidity, and salt spray for tropical island use
• Runs stably at -40℃, cold-proof and anti-condensation
• IEC compliant, complete calibration certificates provided
• Local support: spares, on-site training, and instrument calibration
