Tus neeg xyuas pib yog cov khoom kim tshaj plaws hauv cov kab hluav taws xob siv hluav taws xob, feem ntau suav txog ntau dua 50% ntawm tag nrho cov khoom siv, ntau tshaj li cov insulators, ncej, thiab kho vajtse.
Kev faib nyiaj los ntawm cov khoom:
Tus coj
Cov nyiaj rau 50% -65% ntawm tag nrho cov khoom siv, ua rau nws yog qhov khoom siv loj tshaj plaws.

High-cov kab hluav taws xob xav tau ntau-split conductors, ntxiv cov nqi ntxiv.
Ncej
Tus account rau kwv yees li 20% -30%. Tus nqi ntawm cov yeeb yaj kiab steel yog siab dua li ntawm cov ncej pob zeb.
Ib tug 15-meter pob zeb ncej raug nqi kwv yees li 5000 RMB, thaum ib qho 220kV steel ntauwd tuaj yeem raug nqi 60,000-80,000 RMB.
Customized ntauwd designs yuav tsum tau nyob rau hauv roob roob los yog tshwj xeeb struts, uas ua rau cov nqi ntau dua.
Insulators
Cov nyiaj tau los kwv yees li 10% -15%.
Chav tsev tus nqi ntawm cov khoom siv hluav taws xob raug tshem tawm yog kwv yees li 200 yuan ib thooj, thiab 6-8 daim yog xav tau rau ib tus pej thuam; 500kV kab yuav xav tau ntau tshaj 20 daim.
Hardware thiab lwm yam accessories
Xws li crossarms, txiv leej tub xov hlau, cov khoom siv hauv av, thiab lwm yam, suav txog kwv yees li 10% ntawm tag nrho.
Txawm hais tias tus nqi ntawm chav tsev tsis siab, qhov ntau thiab ntau siv ua rau cov nqi txhawb nqa ntau heev.
