Iintambo zohlobo oluqhelekileyo zilungele ukulinganisa i-AC voltage 0.6 / 1kV kwaye ngaphantsi kweentambo zokuhambisa umbane ngaphandle kweemfuno ze-flame-retardant okanye ezinokumelana nomlilo.
Iintambo zohlobo lwe-flame-retardant alukho lula ukutshisa okanye ukusasazeka kwedangatye kukhawulelwe kuphela kubude obuthile.Iintambo zohlobo oluqhelekileyo zilungele ukulinganisa i-AC voltage 0.6 / 1kV nangaphantsi kwemigca yokuhambisa umbane ngaphandle kweemfuno zokunqanda idangatye okanye ukumelana nomlilo. .
Iintambo zohlobo lwe-flame-retardant alukho lula ukutshisa okanye ukusasazeka kwedangatye kunqunyelwe kuphela kubude obuthile.
Ezi ntambo zifanelekile kwiindawo zokuxinaniswa okuphezulu kweendawo ezifana nezikhululo zamandla, i-subways, i-tunnels, izakhiwo eziphezulu, amashishini amakhulu amashishini, amasimi e-oyile, imigodi, njl.
