Iinqaba zombane, Ezi zakhiwo ziphakamileyo zibalulekile kuthumelo nokusasazwa kwamandla ombane kwimigama emide, ukuqinisekisa ukuba umbane ufikelela ezindlini, kumashishini, nakumashishini. Makhe sihlolisise ukuvela kweenqaba zombane kunye nokubaluleka kwazo kummandla wobunjineli bombane kunye neziseko.
Iinqaba zamandulo zombane yayiziintsika nje zeplanga, ezazidla ngokusetyenziselwa itelegraph neentambo zemfonomfono. Nangona kunjalo, njengoko imfuno yombane yayikhula, izakhiwo ezomeleleyo nezisebenzayo zazifuneka ukuxhasa iintambo zothumelo. Oku kwakhokelela ekuphuhliseni izibonda zensimbi ze-lattice, ezinikezela amandla amakhulu kunye nokuzinza. Ezi zakhiwo ze-lattice, ezibonakaliswe ngepatheni yazo ye-crisscross yeentsimbi zentsimbi, ziye zaba yinto eqhelekileyo kwigridi yombane, emi nde kwaye yomelele ngokuchasene nezinto.
Njengoko imfuno yokuhanjiswa kwamandla ombane aphezulu isanda, kuye kwaba njalo nemfuno yeenqaba ezinde nezihambele phambili. Oku kubangele ukuba kubekho iinqaba zamandla ombane aphezulu, eziyilelwe ukuxhasa ukuhanjiswa kombane kumbane ophezulu kwimigama emide. Ezi nqaba zihlala zakhiwe ngamanqanaba amaninzi e-crossarms kunye ne-insulators ukulungiselela ukunyuswa kwamandla ombane kunye nokuqinisekisa ukuhanjiswa kwamandla okuthembekileyo.
Kwiminyaka yakutshanje, ukuqhubela phambili kwezinto kunye nobunjineli kuye kwakhokelela ekuphuhliseni iinqaba zetyhubhu kunye neenqaba zemibhobho yentsimbi. Ezi zakhiwo zale mihla zisebenzisa uyilo olutsha kunye nemathiriyeli, njengentsimbi ekhandiweyo okanye imathiriyeli edityanisiweyo, ukuphumeza umlinganiselo wokomelela kunye nokumelana nokubola. Ukongeza, ezi nqaba zihlala ziyilelwe ukuba zikhangeleke ngakumbi kwaye zikhuseleke ngokusingqongileyo, zixutywe ngokungenamthungo kwimihlaba yasedolophini neyendalo.
