Insulator Zero-Value Detection Product Series

New Products / New Technology

The product line covers live‑ and de‑energized zero‑value detection for insulators, with live‑line testing supporting the full voltage range from 110 kV to 1000 kV and from ±400 kV to ±1100 kV. The testing method employs an adjustable pulsed high‑voltage approach in the 20 kV to 60 kV range, compliant with the high‑voltage impulse testing procedure specified in DL/T 626‑2024. For live‑line applications, the system further integrates distributed‑voltage measurement, implementing an intelligent detection logic that first measures the distributed voltage and then adjusts the pulsed high voltage accordingly. This approach not only prevents over‑voltage stress that could exceed the insulator's withstand capability but also achieves 100% accuracy in identifying zero‑value and degraded insulators.

Live 10kV Line Connection Tools for Distribution Networks

New Products / New Technology

The complete 10 kV live‑line connection smart toolset enables safe, efficient, and high‑quality execution of the entire wire‑stripping and splicing process. All tools feature a lightweight design, weighing just 3 kg, making them easy for operators to lift. They offer precise, damage‑free wire stripping, synchronized and balanced tightening torque for parallel‑groove wire clamps, and automatic wire‑diameter recognition with adaptive functionality. The system supports voice‑controlled operation throughout the workflow, allowing a single operator to perform the task independently. With a streamlined procedure, customizable stripping lengths, rapid stripping speeds, and highly efficient installation of parallel‑groove wire clamps, the entire stripping and installation process can be completed in under five minutes, significantly boosting operational efficiency.

Visualized Sag Measurement Robot

New Products / New Technology

The visualized sag‑measurement robot seamlessly integrates RTK BeiDou navigation and positioning technology, multi‑sensor fusion techniques, and automated control algorithms. It delivers all‑weather operational capability and can be mounted on drones, enabling efficient, high‑precision wire‑sag measurements. Its key advantage lies in overcoming the environmental constraints of conventional measurement methods, making it particularly well suited for transmission‑line construction phases—such as tensioning and stringing—as well as for challenging conditions like nighttime operations or adverse weather (e.g., rain, fog) under tight project schedules. By eliminating the limitations imposed by lighting and weather, it provides dual assurance: accelerating construction progress while maintaining measurement accuracy.
