Communication facilities are a critical part of our modern infrastructure, essential for information exchange, and as such, they require robust protection. Several years ago, we published on our website a lightning protection project for several such facilities using freestanding lightning rods. In accordance with current Standards and Technical Documentation (STD), we have now updated this design.
The facility is located in the city of Anadyr, Chukotka Autonomous Okrug. The site features permafrost soil, sand, gravel, and clay. It thaws for only two months a year and only to a depth of 0.5 m, with a soil resistivity of 2000 Ω∙m. Such soil is considered "challenging" for implementing a grounding system and achieving the required grounding resistance.
