Innovation prevents damage to power lines

Thanks to innovations by Chinese power workers, large machinery has been kept from damaging power lines during construction work. Staff members from State Grid Xuzhou Power Supply Co in East China's Jiangsu province developed a high-voltage proximity alarm device, issuing voice reminders of different levels when the distance is less than 20 meters, 10 meters and five meters. At a construction site along the Weifang-Suqian High-Speed Railway near the 110 kilovolt Mayun Line, each incoming crane uses such devices, which mainly consist of a sensor and an alarm. Since January this year, they have been installed on 120 sets of machinery, issuing alarms to over 600 users.
