Amid sustained 42°C+ heatwaves in Shanxi and Shaanxi, power crews endure extreme conditions to maintain supply. In Yuncheng (Shanxi), workers perform live-wire maintenance on 10kV lines atop 15m insulated platforms during morning hours. Their uniforms soak through within minutes. In Lintong (Shaanxi), teams inspect subterranean cable tunnels as ground temperatures hit 60°C, using infrared monitors to prevent overload failures. Both regions have deployed dozens of emergency repair teams and heat alert systems to safeguard grids against soaring demand.
