Emkhakheni wocingo lwe-YJV22, i-Y imele i-polyethylene, i-J imele i-cross-linked, i-YJ imele i-cross-linked polyethylene insulation, kanti i-V imele i-polyvinyl chloride sheathing. Izingcingo ezihlome izikhali ngokuvamile zinezibalo ezimbili ezinambeni zazo, lapho isibalo sesibili kusukela ekugcineni sibonisa ukuba khona kwezikhali. Izingcingo ezingahlomisi izikhali azinawo ama-armor. Ngokwesibonelo, i-YJV23 ikhomba i-YJ njenge-cross-linked polyethylene insulation, i-V njenge-polyvinyl chloride sheathing, kanti u-2 ukhombisa i-double steel strip armor, kanti u-3 ukhombisa i-polyethylene outer sheathing.
