220kV Double Loop Transmission Tower
Esikwenzayo
⦁ inkampani yaseShayina edidiyelwe yamandla kagesi, ngokuyinhloko ihlinzeka ngemikhiqizo ehlukahlukene kagesi ezinkampanini zasekhaya nezaphesheya kwezilwandle kanye namakhasimende ezimboni asebenzisa amandla aphezulu.
⦁ Yenza ngokukhethekile umkhiqizi emkhakheni wombhoshongo kalayini kagesi/ipali yokudluliswa nokusabalalisa ugesi, umbhoshongo/isigxobo sokuxhumana ngocingo, isakhiwo sesiteshi esincane, nezinsimbi njll.
Umbono Wethu
- ⦁ UKUBA NGEMPELA ekwenzeni imisebenzi yethu kanye nokuhlinzeka ngezinsizakalo kumakhasimende angaphakathi nawangaphandle.
Power Transmission Tower
Umbhoshongo wokudlulisa noma umbhoshongo wamandla (i-pylon kagesi noma i-pylon kagesi e-United Kingdom, eCanada nasezingxenyeni ze-Europe) isakhiwo eside, ngokuvamile umbhoshongo we-steel lattice, osetshenziselwa ukusekela intambo yamandla engaphezulu.
Asetshenziswa ezinhlelweni zamandla kagesi we-AC kanye ne-DC, futhi afika ngezinhlobonhlobo zomumo nosayizi. Ubude obujwayelekile busuka ku-15 kuye ku-55 m (49 kuya ku-180 ft), nakuba ubude kakhulu kuyimibhoshongo engu-370 m (1,214 ft) ye-2,700 m (8,858 ft) ye-Zhoushan Island Overhead Powerline Tie. Ngaphandle kwensimbi, ezinye izinto zingasetshenziswa, kuhlanganise nokhonkolo nokhuni.
Umbhoshongo we-Angle-steel, umbhoshongo ovamile wokuxhumana wesakhiwo se-quadrangular truss, usebenzisa i-Q345B insimbi yekhwalithi ephezulu njengento eyinhloko yomzimba wombhoshongo, isakhiwo esiqinile, ukuguqulwa okuncane; i-angle steel splicing uxhumano, izingxenye ezinesisindo esincane, umbhoshongo ungathuthwa ngesandla futhi ufakwe ngezindleko eziphansi. Izingxenyekazi eziphezulu ezingu-6 zeplathifomu zingahlonyiswa, inkundla ngayinye isekela izinti eziyisi-6.
ulwazi lomkhiqizo

| Ukushisela | Ukushisela kuhambisana nezinga le-AWS D1.1. |
| I-CO2 yokushisela noma izindlela ezizenzakalelayo ze-arc ezingaphansi kwamanzi | |
| Akukho ukuqhekeka, isibazi, ukugqagqana, ungqimba noma okunye ukukhubazeka | |
| I-welding yangaphakathi nangaphandle yenza isigxobo sibe sihle kakhulu ngesimo | |
| Uma amakhasimende edinga noma yiziphi ezinye izidingo zokushisela, nathi singenza ukulungisa njengesicelo sakho | |
| I-galvanization | I-Hot dip galvanization ngokuhambisana ne-Chinese standard GB/T 13912-2002 kanye ne-American standard ASTM A123; nanoma yiliphi elinye izinga elidingwa yiklayenti. |
| Okuhlangene | Hlanganisa ngemodi yokufaka, imodi ye-flange. |
| Ukudweba | Ngokwesicelo samakhasimende |
i-hot-dip galvanization
