Mugihe umurongo wa T-uhuza umurongo wa 12kV hejuru yo kugabura hejuru cyangwa ikosa ryimbere ryumukoresha wa nyuma bibaye, ihinduka risohoka rya substation rizikandagirwa mugihe igihe cyo gukingira igihe ntarengwa cyo guhinduranya umurongo winjira kandi igihe cyo kurinda umurongo uva kumurongo uhinduranya ntigishobora guhinduka neza. Niba imiterere yamakosa ihoraho, insimburangingo ntizagerwaho, kandi impanuka yabereye mumupaka wumukoresha uciriritse bizatera umurongo wa 12kV gukwirakwiza umurongo. Niba umupaka utandukanya hanze washyizwe kumurongo wa T cyangwa kuruhande rwumukoresha (point de demarcation point), hemejwe ko amakosa (arenze urugero, umuzunguruko mugufi, icyiciro kimwe, nibindi) bibaho kumupaka wabakoresha, kandi amakosa ahita yigunga. Abakoresha ahantu hatari amakosa bakoresha amashanyarazi mubisanzwe. Ikoreshwa rya ZW32-12F hanze yumubyigano mwinshi wubwenge bwimbaraga za demarcation vacuum circuit breaker (watchdog) kumurongo wa 12kV ya federasiyo yo hejuru irashobora kwirinda impanuka zatewe nimpanuka zumurongo utarangwamo amakosa, kugabanya urugero rwumuriro wamashanyarazi, kugabanya igihe cyumuriro wumukoresha, no kurinda umutekano wumurongo wingenzi ukoresha. Kandi ifite umurimo wo gutahura amakosa, kugenzura no gutumanaho, bishobora kumenya kuvanaho mu buryo bwikora ikosa rimwe ryubutaka hamwe no kwigunga byikora byikurikiranya ryicyiciro gito. Ingingo yo kwishyiriraho ikoreshwa kumurongo utandukanya inshingano hagati yumukoresha winjira kumurongo wa 12kV, kandi irashobora no gukoreshwa kumurongo wishami wujuje ibisabwa.

Imiterere isanzwe yo gukoresha:
Ubushyuhe bwibidukikije: ntiburenze + 40ºC, ntiburi munsi ya -15ºC;
Ubushyuhe bugereranije n’ikirere: impuzandengo ya buri munsi ntabwo irenga 95%, naho impuzandengo ya buri kwezi ntabwo irenga 90%;
Uburebure ntiburenga metero 1000;
Imbaraga z’umutingito ntizirenza 8;
Ahantu hatagira umuriro, guturika, umwanda ukabije, kwangirika kwimiti no kunyeganyega gukabije.
