[CCTV] The construction of the first full -process mechanized operations in the country entered the sprint stage

Today, the construction of the 110 -kilovolt transmission and transmission project section of Beitang, located in Zhoushan, Zhejiang, has entered the final sprint stage. As an important part of energy transportation between islands, this time the layout of the cable is different from the past, and for the first time in the country, the whole process has achieved mechanized operation. Where is the advantage of this way of operation? What kind of favorable will this seaside cable bring? At this moment, the reporter Yu Chen was at the construction site of Zhoushan, Zhejiang.

"Hello Yuchen, introduce us to the situation at the scene."

The reporter Yu Chen: Okay, Xiaoning. My position is now in the construction site of the 110 -kilovolt transmission and substation project in Zhoushan, Zhoushan, Zhejiang. The construction ship No. 1 of the Cable 1 is actually appearing among many large maritime operations in Zhejiang. Where is the location of the sea cable? It reaches 2.65 kilometers, it is actually two seaside cables, which is equivalent to two circuits. Power supply.

In fact, before our live broadcast began, the first submarine cable was successfully landed, and now the second submarine cable is sprinting. Why is it so fast? In fact, this is due to the current mechanized operation of the entire process. We said that in addition to the construction boat of the seal cable, there are conventional equipment such as buried plows, and the biggest and biggest improvement links now, is our landing link.

What kind of changes are there? We also prepared two pictures to make an intuitive display for everyone. Come, let's look at this picture first. Like the traditional login method in the past, in fact, we need to open a seaside canal on the sea pond, and then 10 to 20 workers can drag the seaside through the cable through the section of the cable. At the designated position, after the operation is completed, this seaside canal is removed and then restored the sea pond. In fact, it takes time and effort to destroy our environment. Now the directional drilling technology replaces the traditional manual method. The excavation of a underwater tunnel first is first performed on the submarine. Then our traction equipment will draw the seaside cable through the submarine tunnel to our designated position. It turned out that the 6 -hour operation time was shortened to the current one hour. The entire efficiency increased by 83%and saved nearly 20%of the cost. It can be said that the efficiency was greatly improved.

Why do we build two new seal cables here? It turns out that there are already two seaside cables and two overhead lines on this island. Because Zhujiajian Island is the fifth largest island of Zhoushan, and it is also a national -level scenic spot. There are many large projects landing here. According to the data of Zhoushan Power, in the summer of 2023, when the electricity load was the largest, the electricity consumption here increased by 14.43%year -on -year. Therefore, the establishment of two new sea cables can be said to be imminent.

In this construction process, in addition to the landing session, there are other new technologies using the entire process. In fact, there are some new transformations in terms of cable joints. For example, the blue shed place I have come now, it is a dust -free environment made by our cable joint. It was not used to be outdoors before. Our all -armed power workers, in fact, like a power doctor, is like an old Chinese medicine doctor who "watched and questioned" on the seaside we logged in. For a connection, this is also the most important link before the grid.

We have learned that the entire project will be completed in June this year. After the operation is put into operation, the power supply capacity of Zhujiajian Island will be doubled compared to before, and it will continue to ensure the local economic and social development of Zhoushan. At the same time, it will also provide the latest technical solutions and reference for the construction of maritime cables. Good host, my situation here is like this, time is returned to the Beijing studio. "
