220kV kanasonkhezereka zitsulo latisi mphamvu kufala nsanja,
,
Nsanja yotumizira kapena nsanja yamagetsi (pylon yamagetsi kapena pylon yamagetsi ku United Kingdom, Canada ndi madera ena a ku Ulaya) ndi mawonekedwe aatali, omwe nthawi zambiri amakhala nsanja yachitsulo, yomwe imagwiritsidwa ntchito pothandizira chingwe chamagetsi pamwamba.
Amagwiritsidwa ntchito pamakina othamanga kwambiri a AC ndi DC, ndipo amabwera m'mawonekedwe ndi makulidwe osiyanasiyana. Kutalika kwenikweni kumayambira 15 mpaka 55 m (49 mpaka 180 ft), ngakhale zazitali kwambiri ndi nsanja za 370 m (1,214 ft) za 2,700 m (8,858 ft) span ya Zhoushan Island Overhead Powerline Tie. Kuwonjezera pa zitsulo, zipangizo zina zingagwiritsidwe ntchito, kuphatikizapo konkire ndi matabwa.
Angle-zitsulo nsanja, nthawi zonse quadrangular truss dongosolo kulankhulana nsanja, ntchito Q345B apamwamba chitsulo ngati nsanja yaikulu thupi zakuthupi, dongosolo olimba, mapindikidwe ang'onoang'ono; ngodya zitsulo splicing kugwirizana, mbali kuwala, nsanja akhoza kunyamula pamanja ndi anaika pa mtengo wotsika. Magawo 6 a nsanja amatha kukhala ndi zida, nsanja iliyonse imathandizira tinyanga 6.
Zakuthupi | Nthawi zambiri Q345B/A572, Mphamvu Zochepa Zochepa ≥ 345 N/mm² |
