The National Energy Administration has clearly stipulated that the rate of power distribution network live-line operations should reach over 95% by 2025. Live-line operations have become a mandatory assessment indicator for the power industry. It is now urgent to transform grid operation and maintenance towards "less power outages and no power outages". Guangxi Hizoo Technology, closely aligning with the industry's core demands, has launched the HIZ-NT-QZY live-line operation laser obstacle removal equipment, which uses innovative laser technology to solve the problem of obstacle removal on transmission lines, providing solid support for the safe and stable operation of the new power system.
The HIZ-NT-QZY live-line operation laser obstacle removal equipment developed by Guangxi Hizoo Technology Development Co., Ltd. does not require applying for power outage indicators or line shutdowns and load reductions. It is compatible with all voltage levels from 10kV to 500kV and can complete various foreign object removal tasks while the lines are in operation. The entire operation process does not affect civilian electricity use or industrial production, and users hardly notice it, precisely meeting the core demand of "live-line operation and maintenance" in the new power system.
This equipment stands out in terms of work efficiency and operational convenience. It adopts a lightweight and modular design, allowing a single person to quickly set up and operate it without the need for complex training. It can clear common foreign objects such as plastic films, kite strings, and tree branches in 3 to 5 minutes, with an 80% or more improvement in work efficiency compared to traditional methods. For close-range hanging objects within a 100-meter range, it can complete the clearance in as fast as 30 seconds, effectively addressing sudden foreign object hazards on power lines.
Safety performance is the top priority in power grid operation and maintenance. The HIZ-NT-QZY ensures a solid safety line with a non-contact operation mode. The equipment adopts the "Light Blade" remote operation technology, allowing operators to control it remotely from a safe area on the ground. The operation range covers 50 to 300 meters, completely avoiding live electrical parts and high-altitude operation scenarios, eliminating the risks of electric shock and falls from heights at the source. Additionally, it is equipped with an intelligent optical aiming system and a high-magnification electronic telescope, which can precisely lock onto small foreign objects. Combined with millimeter-level aiming accuracy, the clearance success rate exceeds 98%. Moreover, the laser can be reflected by metal wires, ensuring no damage to the line body throughout the process, achieving safe and precise obstacle removal.
