Njengomvelisi oyingcali, singathanda ukukubonelela ngePaidu iSigaba seSithathu seSigaba seSihlanu seCopper Core Flame Retardant. Intambo kufuneka ihambelane nemigangatho yoshishino olufanelekileyo kunye nemimiselo elawula iintambo zombane, kubandakanywa neemfuno zokunqanda umlilo. Ukuthotyelwa kuqinisekisa ukuba ikhebula ihlangabezana nemigaqo ethile yokhuseleko kunye nokusebenza kwayo ekujoliswe kuyo.Iintambo ezithathu ze-five-five copper-core retardant cables zisetyenziswa ngokuqhelekileyo kwiindawo zorhwebo kunye nezoshishino apho ukuhanjiswa kwamandla okuthembekileyo nokukhuselekileyo kubalulekile. Ufakelo nokugcinwa ngendlela eyiyo kwezi ntambo kubalulekile ukuqinisekisa ukhuseleko, ukuthembeka, kunye nokusebenza kakuhle kweenkqubo zombane.
