The mountains are Cui Yan, the wall stands thousands, and the tower stands on the cliff.

After walking through the dumpling river, climbing up the mountainside, looking up at the opposite bank, there were three sections of "hanging" the ladder on the cliff under the tower. Not far away, a waterfall poured from the mountain stream and went down to the pomegranate river. This is an uninhabited area in Yinchang Township, Liangshan Yi Autonomous Prefecture, Sichuan Province.

In the hot summer season, the winding mountain road gradually introduced the reporter and his party into this unmanned area. The forests on both sides of the mountain road are dense, and the mountains are rolling. The trail on the top of the mountain is like a silver ribbon to connect the towering electric tower towering into the cloud. Such a magnificent scenery is amazing, but for the electricity maintenance patrolr, it is both beautiful and hard.

What needs to be inspected by the Tiandi ladder is the No. 79 Tower of 500 KV West Brocade Third Line. "In the past, there was no one -way inspection tower in the tower No. 79 when there was no ladder. The transport inspection team had to choose a good physical technical personnel. With only one steel rope, climbing up step by step along the cliffs and cliffs." State Grid Sichuan Sichuan Sichuan Li Chengjian, deputy head of the operation room of the ultra -high -pressure company Xichangyun Division, pointed at the iron tower on the top of the mountain.

In October 2020, the 3rd section of the steel ladder rack with a total length of 182 meters. Although the climbing time was greatly shortened to 5 hours, and the safety was also guaranteed, but the ladder near the river valley almost made the mountain road full of hardships.

On July 16, 2021, a wire 78 and 79 Tower of Xijin Third Line broke the aging of a wire, affecting the "West East Transmission" of the Jinping Hydropower Station. The Xichang Yunwei Division carefully organized Zhang to hold the equipment for the first time, gathered more than 100 rescue personnel to move more than 10 tons of wire materials to set off overnight. At that time, it was expected that it would take two weeks to repair it. The rescue personnel put the tent on the top of the mountain and fight continuously. In the end, only 7 days were used to complete the repair task.

Liangshan Prefecture is rich in electricity resources, and the transmission lines are spread all over the counties in the country. Among them, more than 200 kilometers of ultra -high voltage electrical lines are located in the uninhabited area in the deep mountains. The climate of the mountains is changing rapidly, and the transmission equipment often faces a variety of natural disasters such as mountain fire, ice covering, thunderstorm, and earthquake.

Regardless of whether it is a hot summer or severe winter, the transport inspection team will penetrate the line of the uninhabited area, trek between the mountain canyons, from a base iron tower to another tower, and on the cycle of tree bamboo, geological hazards, empty floating objects, etc. in the channel Sexual inspections to timely eliminate hidden dangers that affect line safety in a timely manner. Especially from December to February of the following year, it is the superposition of the Daliangshan mountain fire period and the ice -covered period. Workers need to prevent ice while preventing the ice, facing the work pressure of "two days of ice and fire".

The reporter followed the tougard to drive from Xichang City, Liangshan State. Although the scenery was beautiful, the winding mountain road was also unforgettable. With less than 100 kilometers, countless rapid bends and steep slopes, the road under the wheels slowly changed from the original flat cement road to rugged dirt roads. It lasted for nearly 4 hours, and passed the turbulent pomegranate river and crossed the two mountains before finally reaching the destination. The reporter along the way is not easy to sit in the off -road vehicle. The touches can only take a truck in the railway.

"In the uninhabited area, it was a few days, and it was more like a wild survival challenge." Said Jiang Jie, the squad leader of the sixth class of the transmission inspection inspection. Whenever the patrol worker crawls up the top of the mountain to complete the line maintenance, he can only sleep on the tent and clothing by the tower. The food can only eat instant noodles or self -heating rice. In addition to facing the harsh living environment and complex weather, workers must also prevent the invasion of wild animals such as poisonous insects, pythons and even black bears.

State Grid Sichuan ultra -high -voltage company Xichang Transport Division is responsible for operation and maintenance ± 800 kV Jinsu line supporting engineering lines. The 415 base iron tower is built on the steep wall of the uninhabited area.

The 8.4 million kilowatts of Jinping Hydropower Station converted the Yajie River's Tori River into a clean power energy. It was sent to the Xichang Jinping Stream Station through 7 500 kV ultra -high -voltage lines, and then passed through the 800 -kilovolt high -voltage Jinsu line. 2059 kilometers away from Suzhou Tongli Stream Station. With such a group of patrols that are not afraid of hardships and maintaining power supply, it provides a stable guarantee for the production of production and electricity in East China, so that the clean energy of Yazhenjiang River helps carbon reduction emissions thousands of miles away.
