Overhead Transmission Line Ntauwd fabrication siv siab -tensile Q345B steel los tiv thaiv huab cua huab cua thiab cov dej khov sib sau ua ke nyob rau hauv cross- lub teb chaws txoj kev xa khoom. Txhua yam khoom raug kho nrog kub-dip galvanized txheej ntau tshaj 86 microns, ua kom muaj kev saib xyuas- pub dawb lub neej ntawm 50 mus rau 100 xyoo txawm nyob hauv cov av corrosive lossis siab - thaj chaw av noo.
Load thiab environmental parameters
| Qeb Parameter | Qhov taw qhia tseem ceeb |
| Tsim cua ceev | 30-45 m / s (50-60 m / s hauv cheeb tsam typhoon) |
| Dej khov tuab | 0-30 hli (tsawg dua los yog sib npaug li 50 hli nyob rau hauv high-altitude / txias cheeb tsam) |
| Seismic siv zog | 6-9 degrees (raws li GB 50011) |
| Tus neeg xyuas pib / av xaim load | Raws li qib voltage thiab ncua ntev, tension towers muaj ntau dua loads. |
| Ground wire suspension point load | Tsawg dua lossis sib npaug li 2000 kg; Tus neeg xyuas pib crossarm load Tsawg dua lossis sib npaug li 3000 kg |
| Kev muaj peev xwm ntawm lub hauv paus | Ntau tshaj los yog sib npaug rau 150 kPa (Kev siv zog ntxiv rau cov hauv paus mos) |
| Grounding kuj | Tsawg dua lossis sib npaug rau 10Ω (tsawg dua lossis sib npaug rau 5Ω hauv thaj chaw ntub dej) |
Daim ntawv thov daim phiaj tseem ceeb
High-Voltage Grids: Txhawb nqa 110kV rau 1000kV AC/DC kab los txuas fais fab nroj tsuag nrog cov chaw faib hauv nroog.
Hla-Kev Hla Hauv Cheeb Tsam: Kev tsim kho kom ntev- ncua kev ruaj ntseg hla dej ntws, hav, thiab txoj kev loj uas yuav tsum tau tshem tawm hauv av siab.
Substation Connectivity: Ua hauj lwm raws li nro los yog lub davhlau ya nyob twg cov qauv uas tswj cov neeg kho tshuab hloov ntawm cov kab mus rau hauv transformer chaw nres tsheb.
Kev Siv Hluav Taws Xob Hluav Taws Xob: Muab cov hluav taws xob rau txoj hauv kev rau kev loj - cov haujlwm mining thiab thaj chaw tsim khoom hnyav.
Peb lub Hoobkas
Hebei Yifeng Steel Structure Co., Ltd. yog nyob rau hauv "Hometown ntawm Steel Towers," featuring automated CNC kaum steel xuas nrig ntaus kab thiab siab - ceev drilling tshuab. Raws li cov chaw tsim khoom ncaj qha, peb muab kev hloov kho tag nrho rau kev ncua, nro, thiab lub kaum sab xis, kho steel thickness thiab lattice ntom kom tau raws li cov ntaub ntawv huab cua hauv zos. Peb lub voj voog kev sib koom ua ke ua kom muaj kev sib tw Hoobkas- tus nqi ncaj qha thiab lub sijhawm hloov pauv kev ntseeg siab, muab cov neeg siv khoom lag luam nrog lub ntim ntim xav tau rau loj - lub teb chaws lub zog sib tw.
