URUMQI, Nov. 22 (Xinhua) -- Northwest China's Xinjiang Uygur Autonomous Region has deployed an inspection robot in a local substation to monitor and examine its underground power network.

The robot was deployed in a substation in Urumqi, the regional capital on Friday.

Moving along a track and equipped with a high-definition camera and an infrared camera, the robot is able to send real-time footage of the power network to inspection staff, according to Zhou Shuqiang with the State Grid's Urumqi power supply company.

The robot can also identify safety risks with sensors detecting the temperature, humidity and the concentration of toxic and combustible gases.

Zhou said they previously sent two or three staffers every 15 days to inspect the power grid, which was time-consuming and laborious and exposed the inspectors to risks such as fire and gas poisoning.

"The robot reduces risks and saves time, as it's 25 times more efficient than human inspectors," Zhou said, adding that he expects to see the inspection robot used for Xinjiang's underground natural gas and communication networks. Enditem
