With the acceleration of urban infrastructure construction and the vigorous development of low-altitude economy, the risk of external damage to high-voltage transmission lines is continuously increasing. The HIZ-ST-ZNQ high-voltage line anti-external damage intelligent warning ball developed by Guangxi Hai Zhuo Technology is becoming a core equipment for power grid safety protection. With its intelligent and all-weather protection capabilities, it overcomes the passive protection shortcomings of traditional warning devices.
The HIZ-ST-ZNQ high-voltage line anti-external damage intelligent warning ball is a power safety device that integrates intelligent perception, active warning, and long-term protection. The device uses conductor equipotential energy acquisition technology, eliminating the need for external power supply and directly obtaining power from high-voltage conductors, ensuring 24-hour uninterrupted operation. This completely solves the power supply problem for remote lines and meets the core requirements of "zero power outage and low maintenance" for intelligent power grid operation and maintenance in 2026. Its appearance features a high-saturation red and white color scheme, covered with micro-prism reflective film, providing 360° reflective coverage. Even in foggy, backlit, or nighttime conditions, it can be clearly identified from 1.8 kilometers away, with a recognition efficiency three times higher than traditional devices, effectively addressing the visual blind spots of low-altitude aircraft and large machinery.
Active warning is the core advantage of the intelligent warning ball. In 2026, incidents such as construction machinery touching lines, illegal fishing, and low-altitude flight collisions occurred frequently. This warning ball is equipped with a high-precision radar detection module that can monitor external object intrusions within a range of 3 to 6 meters in real time. When cranes, tower cranes, drones, etc., approach the safety threshold, it immediately triggers a 95-decibel voice alarm and high-frequency LED flashing, activating dual warnings simultaneously to alert operators to avoid the area. At the same time, it provides a clear visual warning to ground personnel, effectively reducing the risk of children and temporary workers accidentally entering the area in suburban and rural areas.
The product is made of glass fiber and resin composite materials, featuring corrosion resistance, high-temperature resistance, impact resistance, insulation, and rust prevention. It can adapt to harsh environments such as foggy mountainous areas and high-humidity coastal regions in Guangxi. Installation is convenient and maintenance-free, without interfering with the normal operation of the lines. According to the first quarter 2026 power industry data, the sections of lines equipped with this warning ball have seen a reduction in external damage accidents by over 70%, effectively lowering the risk of power grid failures and large-scale power outages.
