Self Supporting Angle Steel MicrowaveTower
peb yog leej twg
XY Towersyog lub tuam txhab ua lag luam ntawm high voltage kis kab mob nyob rau sab qab teb sab hnub poob Tuam Tshoj.Tsim nyob rau hauv 2008, raws li ib tug tsim thiab pab tswv yim tuam txhab nyob rau hauv lub teb ntawm hluav taws xob thiab kev sib txuas lus Engineering, nws tau muab EPC kev daws teeb meem rau kev loj hlob xav tau ntawm Transmission thiab Distribution (T & D) sector hauv cheeb tsam.
Txij li thaum xyoo 2008, XY yees tau koom tes nrog qee qhov loj tshaj plaws thiab teeb meem kev tsim hluav taws xob hauv Suav teb.
Tom qab 15 xyoo ntawm kev loj hlob tsis tu ncua.we muab array ntawm cov kev pab cuam nyob rau hauv hluav taws xob tsim kev lag luam uas muaj xws li tsim thiab muab kev sib txuas lus & tis kab thiab hluav taws xob substation.
Akis tau tus mob ntauwdlos yog lub zog ntauwd (hluav taws xob pylon los yog hluav taws xob pylon nyob rau hauv lub tebchaws United Kingdom, Canada thiab qhov chaw ntawm cov teb chaws Europe) yog ib tug siab qauv, feem ntau yog ib tug steel lattice pej thuam, siv los txhawb ib tug overhead fais fab kab.
Lawv siv nyob rau hauv high-voltage AC thiab DC systems, thiab tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg.Qhov siab zoo li ntawm 15 txog 55 m (49 txog 180 ft), txawm tias qhov siab tshaj plaws yog 370 m (1,214 ft) yees ntawm 2,700 m (8,858 ft) ncua ntawm Zhoushan Island Overhead Powerline Tie.Ntxiv nrog rau cov hlau, lwm yam khoom siv yuav siv tau, suav nrog pob zeb thiab ntoo.
Lub kaum sab xis-steel pej thuam, tsis tu ncua quadrangular truss qauvkev sib txuas lus ntauwd, siv Q345B zoo hlau ua lub ntsiab ntauwd lub cev khoom, nruj qauv, me me deformation;lub kaum sab xis steel splicing kev twb kev txuas, lub teeb yuag qhov chaw, ntauwd tuaj yeem nqa tau manually thiab ntsia ntawm tus nqi qis.Qhov siab tshaj plaws 6 txheej ntawm lub platform tuaj yeem nruab, txhua lub platform txhawb 6 tus kav hlau txais xov.
Kev txhawb nqa tus kheej feem ntau yog 3- ceg lossis 4- ceg ntauwd thiab nws cov khoom siv yog cov yeeb nkab steel lossis lub kaum sab xis steel
Raws li kev sib txuas, tubular ntauwd txuas nrog lub flange thiab lub kaum sab xis steel ntauwd txuas nrog cov txiv ntseej thiab bolts.
Nta:
1. Me me coefficient ntawm cua load, muaj zog cua tiv taus
2. Txuag cov peev txheej av, qhov chaw yooj yim
Kev thauj mus los yooj yim thiab kev teeb tsa
