The pillar you are talking about is called a tower.
The position of the tower is determined through micro-site selection before installation. The position can be adjusted appropriately before installation. The purpose is to maximize power generation efficiency and not affect local normality (such as avoiding the road, Villages, etc.);; After installation, it cannot be moved. It is very troublesome to dismantle it. Generally, it will not move unless there is a gold mine or valuable dinosaur fossils underneath.
The length of the tower, each model of wind turbine has one or several tower lengths. The length of the tower directly affects the height of the fan. The higher the height, the stronger the air suction capacity. However, the higher the height, the corresponding parameters such as tower rigidity also need to be improved accordingly. . Similarly, after the tower model is selected, the length is also determined. Once it is installed, it will generate electricity until it is decommissioned. During the service process, the length of the tower will not be changed idly.
You're welcome.
About 7 meters.
According to the Road Machinery Network, the height and diameter of the large pillars of wind turbines for power generation are different. The pillars of 72-meter-high wind turbines have a diameter of up to 7 meters.
Wind power tower is the tower pole of wind power generation.
