Yamkela izikhululo ezintathu Sf. Indibano yokutshintsha ukulayisha, ukuhlukana okuhlakaniphileyo kwemigca engenayo kunye neyokunene engenayo kunye neyokuphumayo, uyilo oluncinci lwesakhiwo, umsebenzi oqinileyo wokucwangcisa ikhebula, ukuya kuthi ga kwimigca ye-8 engenayo nephumayo. Le bhokisi yesebe ayigcinanga kuphela uncedo lwebhokisi yokuhanjiswa kwefayibha, kodwa ikwanazo ezinye zeenkxalabo zeringi yeyunithi engundoqo. Sisixhobo esifanelekileyo sokuguqulwa kothungelwano lwasezidolophini. Ubungakanani obuncinci, ukugcinwa-simahla, uqoqosho oluhle lobugcisa, ukuthembeka okuphezulu, ukufakwa okulula kunye nokusetyenziswa okufanelekileyo.

Nge-SF. Iimpawu zebhokisi yesebe yombane yokutshintsha komthwalo yilezi: kukho amacandelo amathathu kwi-compartment, enye ivalwe. Ikhompatimenti etywiniweyo izaliswe yigesi yesulphur hexafluoride ecinezelekileyo kancinane, kwaye kukho ngaphezu kweqela elinye lokutshintsha komthwalo kuyo. Indlela yokusebenza yokutshintshwa komthwalo ifumaneka kwindawo yokusebenza yokuqhuba. Kukho imigca yemfumba yombane kunye neeterminals zombane kwi-compartment wire compartment, kwaye ii-terminals zombane zixhunyiwe kwi-switch load. Ukutshintsha komthwalo kwindawo yokutshintsha umthwalo otywiniweyo yi-turntable eguquguqukayo kunye ne-static contact load switch. Ishafu ejikelezayo yokutshintsha komthwalo ngamnye inemigangatho emithathu kwi-symmetrical fan-shaped plane ejikeleze i-axis. Iintambo kwi-cable compartment zikwiqela lezigaba ezintathu, kwaye i-terminals ezintathu zombane kwiqela ngalinye zihanjiswa ngokufanayo kunye ne-diagonally phantsi. Izithuba ze-terminal ze-viper yombane nganye ziqhagamshelwe ngokuthe nkqo kwiintambo zombane zokwandisa, kwaye imigca emithathu yemfumba yombane yokwandisa ihambelana enye kwenye. Indawo etywiniweyo inombhobho woxinzelelo.
