Thola ukukhetha okukhulu kwe-Copper Power Cable enama-3 Cores avela e-China e-Paidu. Izintambo zikagesi wethusi kufanele zihambisane nezindinganiso nemithetho yemboni efanele, njengamazinga e-IEC (International Electrotechnical Commission), izimfuneko ze-NEC (National Electrical Code) kanye namanye amazinga esifunda. Ukuthobelana kuqinisekisa ukuthi izintambo zihlangabezana nemibandela ethile yokuphepha nokusebenza okuhlosiwe kwazo.Izintambo zamandla ethusi ezinama-cores amathathu zisetshenziswa kabanzi ekudluliselweni kwamandla nokusabalalisa ezimbonini ezihlukahlukene kanye nezinhlelo zokusebenza ngenxa yokuqina kwazo, ukwethembeka, namandla asebenzayo okudlulisa amandla. Ukukhetha kahle, ukufakwa, nokugcinwa kwalezi zintambo kubalulekile ukuze kuqinisekiswe ukuphepha nokusebenza kwezinhlelo zikagesi.
