Intambo eqinile yamaminerali enesembozo, 1 core × 185 mm², amandla kagesi alinganiselwe 750 V. Izinga: Yenziwe ngokuya nge-GB/T 13033.1 ne-IEC 60702-1 (izintambo zamaminerali ezisembozwayo). Ukusetshenziswa: Izintambo ezibalulekile emlilweni nasezingeni lokushisa eliphezulu — izintambo ze-alamu yomlilo nezokukhanyisa okuphuthumayo, iziko lezimboni, amakamelo amabhoyela nezikhungo zamandla enuzi; lapho intambo kumele iqhubeke isebenza emlilweni. Izici: I-magnesium oxide (MgO) esembozweni esingenawo umthungo wethusi ayishisi nhlobo, isebenza emazingeni okushisa aphezulu kuze kufinyelele ekuncibilikeni kwethusi; ukuminyana kwamandla kagesi okuphezulu kakhulu; imelana namafutha, amanzi nomlilo; idinga ukuphethwa okuvaliwe. Amapharamitha obuchwepheshe: 1 core × 185 mm² umthwali wethusi, amandla kagesi alinganiselwe 750 V.
