Kwenzeka ntoni xa utsiba iMigangatho yokuThotyelwa kweMigangatho yeeNtambo zeZixhobo?
- Impendulo Ethe Tye: Ukungathobeli Kubiza Kakhulu Kwaye Kuyingozi
Abantu bahlala bebuza:"Kutheni kubaluleke kangaka ukuthobela imigangatho yekhebula lezixhobo?"
Impendulo elula:Idatha yoshishino ibonisa ukubaAma-80% ofakelo lweentambo zezixhobo ezingathobeliyo afumana iingxaki ezinkulu kwiinyanga ezili-18– ukusuka kwiimpazamo zesignali ezingapheliyo ukuya ekusileleni ngokupheleleyo kwenkqubo kunye neengozi zomlilo.

| Ukusilela kwezixhobo | Iisekethe ezimfutshane, iimpazamo zomhlaba, ukwaphuka kwe-insulation | Ixesha lokuphumla elingacwangciswanga ($10,000-$500,000/iyure) |
| Iingozi zokhuseleko | Ukusasazeka komlilo (intambo engatshisi ilangabi), ukutshayiswa ngumbane, umngcipheko wokuqhuma (iindawo ezinobungozi) | Ukulimala, ukufa, ukutshatyalaliswa kwezityalo |
| Ukwaphulwa kwemithetho | Iingcaphuno ze-OSHA, ukungathobeli imithetho ye-NEC/IEC, ukwaliwa kwebango le-inshorensi | Iintlawulo, imiyalelo yokuvala, amatyala oxanduva |
| Ukwaliwa kweprojekthi | I-EPC/umthengi uyala ukwamkela intambo engaqinisekiswanga | Iindleko zokubuyisela imali, ukulibaziseka kweprojekthi |
Eyona Nto Ibalulekileyo:Ukutsiba ukuthobela imithetho ukuze wonge i-10-20% kwixabiso leentambo kudla ngokuphumela ekubeniIxabiso lilonke elingaphezulu nge-10-100×xa kuthathwa amanyathelo okusilela, ixesha lokungasebenzi, kunye nokulungiswa kwakhona.
(Yi-20% kuphela yeenkqubo ezihambelanayo eziphumelelayo ngelixa ezinye zisilela kwiinyanga ezili-18)
KwiDingzun Cable,Zonke iintambo zethu zezixhobo zihambelana ngokupheleleyo ne-EN 50288-7, i-IEC 60332, kunye neemfuno ze-NEC/CE ezifanelekileyo - kunye neengxelo zovavanyo ezibhaliweyo zokungqina oko. Ukuthobela imithetho akuyondlela ifanelekileyo; ngumgangatho wethu.
- Idatha: Izinga lokungaphumeleli lokungathobeli imithetho elingama-80%
Izifundo zoshishino kunye nedatha yentsimi zibonisa rhoqo ukuba iintambo ezingathobeliyo ziyasilela ngamanani aphezulu kakhulu.
Itheyibhile 1: Ukuthobela imithetho vs Ukungathobeli imithetho – Uthelekiso lwezinga lokusilela
