220kV Double Loop Transmission Tower
Zimene Timachita
⦁ Kampani yamagetsi yophatikizika yaku China, makamaka imapereka zinthu zosiyanasiyana zamagetsi kumakampani opangira magetsi apanyumba ndi akunja komanso makasitomala amakampani omwe amagwiritsa ntchito mphamvu zambiri.
⦁ Khazikitsani makina opanga ma transmission tower/pole potumiza ndi kugawa magetsi, nsanja yolumikizirana ndi telecommunication tower/pole, substation structure, ndi zoyikira zitsulo ndi zina.
Masomphenya Athu
- ⦁ Kukhala WABWINO pogwira ntchito zathu ndikupereka chithandizo kwa makasitomala amkati ndi akunja.
Power Transmission Tower
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.
