Warmth from power workers in cold winter

CHONGQING (CQNEWS) -- It is in cold winter, and snow and chill wind occur in many high altitude areas in Chongqing. Power workers of State Grid Chongqing Electric Power Company have to cut through the mountains against wind and snow. They inspected faults of electric power circuit in desolate mountains to ensure safe power supply. When you enjoy the beautiful city decorated by gorgeous lights and feel the warmth of home showed by lights, please don’t forget those power workers who step on the snowfield and inspect in mountains to protect the power project.

Chepan Mountain, with an altitude from 1,000m to 2,000m, is 90-minute drive from Wulong District, Chongqing. The 500KV Zhangjiaba - Longsheng Transmission Project goes by. When it comes to the coldest time every year, the temperature here may be -10℃. In order to ensure the power supply, workers from Transmission and Distribution Project Co., Ltd. of State Grid Chongqing Electric Power Company should make regular inspection at fixed spots to observe the melting ice.

In winter, Chepan Mountain is covered by snow and ice. From afar, it looks like a fairy tale world. The snow-covered tower is like a "white giant" guarding this mountain forest.

Many people may be curious about that ice has little impact on the iron tower and transmission lines. In fact, thick ice will cover the tower and power lines in rainy and snowy days. As water is the conductor, the frozen ice can be conductive, which will make the grid fail resulting from short-circuit.

It is self-evident that the inspection work is tough. Workers working uphill often encounter the situation when the mountains were blockaded by the snow. When the snow is heavy, vehicles can’t drive on many sections of the roads. Power workers need to walk a few kilometers to the fault spot to conduct repair work. They may be tumbling down on the slippery roads.
