Malo okwererapo amakhala ndi zinthu zitatu zofunika kwambiri: makina, mphamvu zamagetsi ndi chilengedwe.

　　1. Mphamvu yamagetsi

　　Chingwe cholumikizira chikagwiritsidwa ntchito ngati waya wolumikizira, choyamba, magwiridwe ake ayenera kukhala magetsi.

　　Makawirikawiri akuphatikizapo: kukana kukhudzana, kukana kutsekereza ndi mphamvu ya dielectric.

　　1. Kukana kulumikizana, zolumikizira zamagetsi zapamwamba ziyenera kukhala zotsika komanso zokhazikika.

　　2. zolumikizana ndi pakati pa zolumikizira ndi chipolopolo.

　　3. Mphamvu ya dielectric ndiyo kupirira voteji ndi dielectric kupirira voteji.

　　　 2. Mechanical properties

　　Kachitidwe ka makina makamaka kumaphatikizapo kuyika mphamvu ndi moyo wamakina wa cholumikizira. Mphamvu yoyika ndi kutulutsa ndi moyo wamakina a terminal imagwirizana ndi mawonekedwe olumikizirana (kukakamiza kwabwino), mtundu wokutira wa gawo lolumikizana (gawo lotsetsereka) ndi kulondola kwapang'onopang'ono (kulumikizana) kwa njira yolumikizirana.

3. Environmental performance

　　Zinthu zodziwika bwino zachilengedwe zimaphatikizapo: kukana kutentha, kukana chinyezi, kukana kupopera mchere, kugwedezeka ndi kugwedezeka, ndi zina zambiri.
