Power Transmission Tower
A transmission tower kana power tower (electricity pylon kana electric pylon muUnited Kingdom, Canada and parts of Europe) chimiro chakareba, kazhinji chishongo chesimbi, chinoshandiswa kutsigira tambo yemagetsi pamusoro.
Iwo anoshandiswa mune yakakwira-voltage AC uye DC masisitimu, uye anouya akasiyana-siyana maumbirwo nehukuru. Kureba kwakajairika kunotangira pagumi nemashanu kusvika pamakumi mashanu nemashanu m (49 kusvika 180 ft), kunyangwe akareba ari 370 m (1,214 ft) shongwe dze2,700 m (8,858 ft) span yeZhoushan Island Overhead Powerline Tie. Mukuwedzera kune simbi, zvimwe zvinhu zvinogona kushandiswa, kusanganisira kongiri uye huni.
Angle-simbi shongwe, yakajairwa quadrangular truss chimiro chekutaurirana shongwe, uchishandisa Q345B yemhando yepamusoro simbi seyo huru shongwe yemuviri zvinhu, yakasimba chimiro, diki deformation; angle iron splicing connection, light-weight parts, tower inogona kutakurwa nemaoko uye kuiswa pamutengo wakaderera. Maximum 6 akaturikidzana epuratifomu anogona kuve akashongedzerwa, yega yega inotsigira matanhatu antennas.
