Inqubo yokuthuthukiswa kokuphakanyiswa kwengulube yengulube ingahlukaniswa izigaba ezi-3.
Ekuqaleni, ingxenye yesigaba sokwenza umsebenzi, okungukuthi, ukukhiqizwa kwengulube kwezixhumanisi ngazinye ekusetshenzisweni kwemisebenzi emishini, kepha kusadinga ukufakwa ngenani elikhulu labasebenzi bezandla, ukukhiqizwa kwamakhilogremu angama-3 35 umsebenzi.
Kulesi sigaba sokusetshenziswa komshini, isixhumanisi esikhulu sokukhiqizwa kwengulube ikakhulukazi sisebenza ngomshini, kepha futhi kudingeka futhi sifakwe ngenani elincane lomsebenzi wezandla, imvelo yemvelo nayo inokuncika kwengulube yamakhilogremu ayi-12.
Isiteji sefektri senza ukukhiqizwa kwengulube kube nesimo sokukhiqizwa kwezimboni, inqubo yokukhiqiza usebenzisa indawo yemvelo yengulube ekukhiqizeni okumaphakathi, ukukhiqizwa kwamakhilogremu kuncishiswe kakhulu, ukukhiqizwa kwamakhilogremu ayi-2 acishe adinga amahora ayi-1 ~ 2.
