Avoid preta, also known as anti-Reta, Consumers Leita, depending on the material used can be divided into round to avoid Leita and angle to avoid preta, according to different functions can be divided into two kinds of lightning and lightning-line tower towers, to avoid Leita round used widely because of its low cost materials can be used to avoid Leita bar, angle, pipe, steel and other single, height range 18 m -68 m The company produces avoid Leita include: lightning rod tower lightning decorative tower, eliminator tower.
Purpose applied Thunderstorm for protection and building roof, power plants, forest, fuel storehouse, weather stations, factory floor communications base stations, radar stations, airports, oil depots, missile positions, PHC and various base stations, paper mills, and other important place.
Advantages: As used in the steel tower materials, wind load factor is small, strong wind resistance, tower with external flange connection, bolt tension, not easy to damage, reduce maintenance costs pylon positive triangular layout, save steel. with open, small footprint, saving land resources, convenient location, tower light weight, easy transportation and installation, short construction period. tower wind load curve design, smooth lines in case of a rare hurricane easily collapse, reducing livestock casualties, designed to meet the national steel tower mast design specifications and design procedures, construction safety and reliability.
Anti-damage ability: Wind 10 / earthquake six
Lightning principle: the lightning current air-termination system is a non-inductive, low-impedance metallic conductor drop, after the lightning arrester lightning current to earth, and to be protected antenna tower or building Sideswipe does not occur and charged, in most cases, the impact is less than the electrostatic field cable impedance Tower 1/10, avoid building or tower charged, flash mine eliminate limits on landmines current strength, so by reducing the counter-attack and protective equipment hazards induced overvoltage the scope of protection calculated in accordance with international law GB50057 ball.
