Ikhebula Elilukhuni Elenziwe Ngamaminerali Agqinsiwe, umgogodla ongu-1 × 185 mm², amandla kagesi alinganiselwe angu-750 V. Izinga: Lakhiwe ngokuhambisana ne-GB/T 13033.1 kanye ne-IEC 60702-1 (amakhebula enziwe ngamaminerali agqinsiwe). Izinhlelo zokusetshenziswa: Izintambo zikagesi ezibalulekile emlilweni kanye namazinga okushisa aphezulu — amasekhethi e-alamu yomlilo kanye nokukhanyisa okuphuthumayo, iziko zokuncibilikisa izinto embonini, amagumbi ama-boiler kanye nezikhungo zamandla enuzi; lapho ikhebula kufanele liqhubeke nokusebenza emlilweni. Izici: Ukufakwa kwe-magnesium oxide (MgO) esikhwameni sethusi esingenamthungo akukwazi ukusha nhlobo, kusebenza emazingeni okushisa aphezulu kuze kufike endaweni yokuncibilika kwethusi; ukuminyana kukagesi okuphezulu kakhulu; kumelana namafutha, amanzi kanye nomlilo; kudinga iziphetho ezivaliwe. Amapharamitha obuchwepheshe: umgogodla ongu-1 × 185 mm² wethusi, amandla kagesi alinganiselwe angu-750 V.
