Iisekethe ezinde kufuneka zidibanise amacandelo amabini okanye ngaphezulu kwentambo enye kwenye, efuna ukudibanisa okuthe ngqo. Isiqhagamshelo esithe ngqo sisincedisi esidibanisa iintambo ezimbini ukwenza isekethe eqhubekayo, ngakumbi isiqhagamshelo esinegobolondo yentsimbi yesiqhagamshelo sisebenza ngombane kunye nesikhuselo sesinyithi kunye nesikhuselo se-insulation sentambo edibeneyo. Ukuze kuncitshiswe amandla ombane we-electromotive we-sheath yesinyithi, imigca yombane ephezulu ifuna i-insulation joints ukuqonda uqhagamshelo olunqamlezayo, ukuze kupheliswe ukujikeleza kwangoku okwenziwa ngamandla e-electromotive force. Isidibanisi esigqunyiweyo Isiqhagamshelanisi esiqhawula ngombane isingxobo sesinyithi, ikhaka lentsimbi kunye nekhuselo lokugquma lentambo. Iintambo zekhebula, ngokwendima yazo kumgca, ngaphezu kweengqungquthela ze-insulation kunye neendawo ezithe tye, zinokuthi zibe namagatsha esebe kunye nangaphezulu.
