During the annual spring and autumn windy seasons, plastic films and discarded mulch films scattered across rural farmlands become "invisible killers" for power transmission lines. These seemingly insignificant airborne debris, once lifted by strong winds, can wrap around high-voltage wires or transmission towers—causing minor issues like line discharges and tripping, or more serious consequences such as widespread power outages and even fires.
To tackle this seasonal challenge, power supply companies across various regions have organized inspection teams and mobilized local communities to conduct thorough sweeps of transmission corridors and surrounding areas within 500 meters, targeting plastic greenhouses, mulch-covered fields, and color-coated steel roof sheds. Maintenance personnel actively assist farmers in clearing residual plastic films, burying them deeply or transporting them away, thereby reducing the threat posed by airborne debris at the source.
Yet, despite these efforts, some hazards inevitably slip through. When foreign objects still end up entangled on power lines, traditional clearance methods reveal their limitations: requesting power outages affects hundreds or thousands of households, while manual climbing and live-line operations are both dangerous and time-consuming, taking at least two to three hours per incident. Is there a faster solution?
Guangxi Haizhuo Technology's HIZ-NT-QZY laser obstacle-clearing device offers an answer. This system functions like a "laser surgical unit"—operators stand safely on the ground, using a high-definition visual screen to clearly identify plastic bags or kite strings tangled on power lines over a hundred meters away. After locking onto the target, a single button press emits a high-energy laser that precisely focuses on the object, instantly melting and carbonizing it so it naturally detaches. The entire process is conducted from a safe distance, with accurate targeting and powerful impact—all without power interruption, tower climbing, or physical contact.
The principle behind laser obstacle removal is simple: using the thermal effect of high-energy lasers to rapidly heat and melt non-metallic debris. What truly enables its intelligent implementation, however, lies in its advanced technical specifications—300x electronic zoom targeting, millimeter-level laser spot control, and multiple safety protections.
The Haizhuo laser obstacle-clearing instrument is compatible with transmission lines ranging from 10kV to 1000kV. It can cut not only plastic films but also remove kite strings, branches, wasp nests, and other potential hazards. It is transforming grid maintenance work from a "high-risk, labor-intensive task" into a precise, ground-based operation.
