I-switchgear yensimbi ye-KYN28-12 iyisigaba sesithathu se-AC 7.2-12kV, 50Hz yangaphakathi ye-high-voltage switchgear, futhi ingahlonywa ngenhlanganisela yefomu le-microcomputer ehlakaniphile, i-telemetry, isilawuli kude, ukuxhumana okukude nokungagadiwe. Zonke izinqola zezandla zomkhiqizo zishayelwa isikulufu, futhi umnyango wekhabhinethi uvaliwe ngemuva kokuthi i-trolley ingene endaweni yokuhlola. Izinto zohlaka zithunyelwa ngaphandle kwe-aluminium zinc plate, ukusetshenziswa kwesakhiwo somhlangano, ukufakwa kalula, amandla amahle, hhayi ukuguquguquka, ikakhulukazi ezisetshenziswa ezitshalweni zamandla kagesi wesistimu, iziteshi ezingaphansi, amabhizinisi ezimboni nezimayini, imiphakathi yokuhlala, ugesi wesikole, imboni yezokwakha kanye neminye imikhakha. ukwamukela nokusabalalisa amandla kagesi, ukuqaliswa kokulawula, ukuvikela, ukuqapha.
