What are the legal insights into the conflict between tree lines?

The power supply department explained in detail

The "tree line contradiction" has been around for a long time. The masses are worried about this and the relevant departments have a headache. How to solve this contradiction has become the focus of everyone's attention. . In this regard, the reporter specially interviewed the relevant person in charge of the urban power supply branch, and the other party answered the questions that everyone was concerned about.

"The 'tree-line contradiction' has appeared since the establishment of lines." According to Ren Xuan, deputy manager of the urban power supply branch, accidents occur every year in the city due to cables hanging from trees. Although most of them are The unplanned power outage caused by line tripping never caused personal injury or property damage, but it caused inconvenience to the production and life of people and enterprises. For this reason, the power supply department has also been looking for solutions to avoid accidents.

Implement cable transformation - the most fundamental solution

Burying the cables underground without any chance of contact with trees is naturally the most fundamental way to avoid danger. Since 2001, the urban power supply branch has begun to bury cables underground on newly built and renovated roads. As the road construction progresses, the cables will be buried underground at one time, such as the Shengli North Road that began to be renovated in 2002 and 2003. This method is implemented on the Century Road that was built and the roads such as Malu Street and Wucheng Street that were renovated this year. The company has also reached an agreement with the High-tech Zone Management Committee. In the future, whenever the High-tech Zone needs to lay or transform cable lines, the High-tech Zone Management Committee will be responsible for making cable trenches, and the urban power supply branch will be responsible for investment in electrical equipment. At present, the trenches on Jing'er Road have been completed and the cables are about to be put into the ground. The next step is to make trenches on Wei'er Road.

Although it is more expensive to install cables in the ground, it also has many benefits: there will be no road poles on the road, and there will be no "spider webs" in the sky, which is both beautiful and avoids the problem of "tree line contradiction" produce. According to reports, this method has been included in the "Eleventh Five-Year Plan" of our city's power supply department, which is also the development direction of our city's power grid.

Insulation transformation - implementation of roads with complex pipelines

Due to the high cost of cable transformation and the high requirements on road conditions, most of the road surfaces in our city are currently It is relatively narrow. When all kinds of lines have to occupy one area, the underground space cannot be arranged, so the cable insulation transformation method is adopted to replace the cable "coat": the outer layer of the high-voltage line is 3.4 mm thick, and the outer layer of the low-voltage line is 3.4 mm thick. is 1.2 mm. After testing, this kind of insulation layer has strong insulation and wear resistance. It will not cause any harm to the human body. At the same time, it will not be damaged by friction with trees under normal circumstances for 20 years. This method is generally used for line reconstruction of some old roads, such as Mingde North Street, Industrial Street, Changqing Road and other roads.

Every year, the urban power supply branch carries out planned insulation transformation of the lines. This year, 14 kilometers of transformation have been completed.

Pruning trees - temporary measures

For those lines whose funds have not been included in the plan or are waiting for approval from superior departments, the urban power supply branch can only prune trees to ensure that Avoid the danger of being too close to each other.

According to reports, the total length of urban cable lines in our city is 567.4 kilometers, of which only 34 kilometers are grounded and insulated, and the rest are exposed lines. To this end, the urban power supply branch has an operation team that patrols along the lines every day. Once any problems are found, they will immediately report them to the biotechnology department of the unit. After communicating with the greening and other departments based on the actual situation, a maintenance team will be arranged to prune them. After pruning, the cut branches must be cleaned up. This is the route mentioned in the article "Transmission lines running through trees, posing safety hazards" published in Zhangjiakou Daily on September 22. The high-voltage lines in this section of the line have been insulated, but the low-voltage The lines have not been renovated yet. The urban power supply branch had pruned the trees here before, but because the trees continued to grow, it could only continue to arrange special personnel and vehicles to prune them.

However, Deputy Manager Ren Xuan said that the reconstruction plan for this section of the line has been reported to the superior department and is now waiting for funding approval.

Deputy manager Ren Xuan said that due to the limited personnel and vehicles in the maintenance team, some areas that needed to be pruned were not able to arrange personnel in time, causing hidden dangers. The company is considering investing more manpower and material resources next year.
