Pakuti zingwezi zimagwiritsidwa ntchito pokumba zinthu zovuta komanso malo ovuta, zodzaza ndi mpweya ndi matope, zomwe zimawonetsedwa mosavuta, zingwe zamagetsi zoteteza moto zapulasitiki zomwe zimatetezedwa sizimangokhala ndi zinthu zomwe zatchulidwa mu chaputala choyamba cha bukuli, komanso zimakhala ndi mphamvu yoteteza moto kwambiri. Pakati pawo, imodzi yomwe malo ake okwana 50mm ndi kupitirira apo iyenera kudutsa mu kuyesa kuyaka kwa A type Collecting Electric Wire & cable. Ngati ndi yochepera 50mm², iyenera kudutsa mu kuyesa kuyaka kwa B type collecting electric wire & cable.
1. Kutentha kwambiri kwa ntchito
2. Kukhazikika kwamphamvu kwa ntchito komanso kukana moto, zomwe zimathandiza kuti chingwe chikhale ndi moyo wabwino.
3. Chitetezo cha kuphulika
4. M'mimba mwake wakunja waung'ono
5. Mphamvu yayikulu yamakina
6. Mphamvu yayikulu yonyamulira magetsi
7. Kukana dzimbiri kwambiri
Chingwe chamtunduwu ndi choyenera kugwiritsidwa ntchito poyika zinthu mu mizere yotumizira/kugawa magetsi yoposa 10kV monga malo ochokera ku chipinda chogawa magetsi chapakati kupita ku chipinda chamagetsi, malo osinthira magetsi a movab-e, malo ogwirira ntchito ophatikizira migodi ndi switchgear. Chingwechi chili ndi mphamvu yoletsa moto.
