Ubonelelo lwefektri j iibholithi zokufulela iihuku

j iibholiti zokuphahlakweenyawo zathathwa ngohlobo, kwaye eyona nto ibonakala ingcono kakhulu kunale foto. IUbonelelo lwefektri j iibholithizenziwe ngeyona nto ingcono kakhulu ye-carbon steel material. Hayi, umphezulu weJ BOLTifakwe igalvanized, ekwaziyo ukumelana nomhlwa kwaye iqinile. Amandla aphezulu kakhulu, kwaye thina aifektri yokuqinisa, enokuvelisa iinkcukacha ezahlukeneyo kunye nobukhulu.
