| Resumo: | This paper aims to present the necessary requirements for the execution of a crossing on a Brazilian highway with medium voltage networks from a wind power plant, addressing the signage and documents required by DNIT – National Department of Infrastructure for Transportation.
The study covers the two most common methods for conducting the topographic survey of the park: using drones or total stations. This study is of great relevance for the project's development, as it enables the gathering of crucial information to facilitate its execution.
The study also includes the presentation of the necessary formulas for calculating the heights and stresses of the poles, taking into account the regulations, information obtained from cable and pole suppliers, as well as temperature and wind data obtained from the region where the wind power plant is being implemented.
The importance of planimetry and altimetry in the execution project of the crossing is discussed, as well as the need to follow DNIT's regulations and guidelines, such as locating the poles outside the highway's right-of-way and ensuring that the cable catenary crossing the road complies with the minimum cable-ground height specified in the regulations, to guarantee the safety of professionals and highway users. Additionally, the importance of proper signaling, such as regulatory and warning signs, as well as cones, is addressed to ensure the safety of the crossing's execution.
In conclusion, the execution of a crossing on a Brazilian highway with medium voltage networks requires careful planning and attention to legal and safety requirements, to ensure maximum efficiency of the facilities and their complete safety. |
