Isixhumi esingangeni manzi sidlala indima ebalulekile njengesisetshenziswa sikagesi esixhuma ukuphela kokunikezwa kwamandla kanye nokuphela kwesidingo.Ngenxa yalesi sizathu, lapho ukhetha izingxenye zikagesi ezine-voltage ephansi ezimotweni zabagibeli, kuyadingeka ukukhetha okuhle kakhulu ezicini zemvelo, izinga lokushisa, umswakama, ukuqondiswa kwemishini, ukudlidliza, uthuli, ukungangeni kwamanzi, umsindo, ukuvala uphawu, njll.
Isixhumi esingangeni manzi sakhiwe ama-sub-assemblies amabili, isiphetho sowesilisa nesiphetho sesifazane.Isiphetho sesifazane sakhiwe ngomzimba kamama, ilokhi yesibili (itheminali), indandatho yokuvala, itheminali, iringi yokuvala, isembozo nezinye izingxenye.Ngenxa yezakhiwo ezahlukene, kuzoba khona umehluko ngamunye ezingxenyeni ezinemininingwane, kodwa umehluko awumkhulu futhi unganakwa ngokuyisisekelo.
Isixhumi esifanayo esingangeni manzi ngokuvamile sihlukaniswa ngeziketi ezinde neziketi ezimfushane.
