Tumizani ImeloZingwe zapakati pa mlengalenga za Voltage zimagwiritsidwa ntchito kwambirimizere yachiwiri yapamwambapamitengo kapena monga zodyetsera kumalo okhalamo. Amagwiritsidwanso ntchito potumiza magetsi kuchokera kumitengo kupita ku nyumba. Kupereka chitetezo chokwanira komanso kudalirika, kumalimbana ndi nyengo yovuta, cheza cha ultraviolet, komanso kupsinjika kwamakina. Ndi yosavuta kuyiyika ndi kukonza, yokhala ndi ndalama zotsika mtengo, imagwiritsidwa ntchito pafupipafupi pogawa magetsi m'matauni ndi kumidzi.
Zokhazikika:
IEC 60502-2---- Zingwe zamagetsi zokhala ndi zotchingira zotuluka ndi zida zawo zovotera kuchokera ku 1 kV (Um = 1.2 kV) mpaka 30 kV (Um = 36 kV) - Gawo 2: Zingwe zama voliyumu ovotera kuchokera ku 6 kV (Um = 7.2 kV) mpaka 6 kV = 3 kV = 30 kV
