KD-212L Street Light Cable Fault Tester | Underground Cable Locator & Inspector

Applications:

The KD-212L Street Light Cable Fault Tester is a specialized instrument designed for the maintenance and troubleshooting of street lighting cable networks. It is primarily used to detect grounding faults, including short-circuit grounding and open-circuit grounding, in low-voltage underground cables. This system is essential for municipal engineering, power utility maintenance, and facility management, allowing technicians to quickly locate faults in complex cable routes without excavation. It is particularly effective in environments with dense cable layouts and is suitable for both preventive maintenance and emergency repair scenarios.

Profile:

The KD-212L is an integrated underground cable fault detection system developed by Wuhan Kaidizhengda Electric Co., Ltd. Engineered specifically for the unique challenges of street light cabling, this device combines a microcomputer central processor with dedicated integrated circuits to deliver high sensitivity and strong anti-interference capabilities. The system adopts a "one-key" operation design, simplifying what is traditionally a complex testing process into a tool-like workflow that requires minimal training. Powered by a large-capacity battery, it ensures extended field operation time. The A-frame (Insulation Receiver) features a streamlined, integrated circuit board design that eliminates the hassle of external wiring, enhancing durability and reducing failure rates in harsh outdoor conditions.

Features:

  • All-in-One Fault Detection: Capable of precisely locating grounding faults (short-circuit and open-circuit) in street light cables.
  • Dual-Mode Routing Detection: Utilizes both Peak Method (for rough routing) and Null Method (for precise routing) to accurately trace cable paths and determine burial depth using a triangular calculation principle.
  • Intelligent A-Frame (Insulation Receiver): Features an integrated electronic board design that synchronizes with the transmitter to detect fault direction and signal strength, visually indicating the exact fault point location via LED arrows and bar graphs.
  • User-Friendly "One-Key" Operation: Designed for simplicity; users can master the device after a single operation, effectively enabling "no-training" usage.
  • Extended Detection Range: Can detect faults over long distances (up to 25km) with high accuracy, even in environments with significant signal attenuation.
  • Robust & Field-Ready: Built with high static drift stability and strong anti-interference technology to ensure reliable performance in various soil conditions and industrial environments.
  • Depth Measurement Capability: Accurately calculates cable burial depth (up to 3m) using a 45-degree angle measurement technique, minimizing errors caused by surface obstacles.
