China 20kV kutentha kuotcha chingwe Chalk fakitale ndi opanga

20kV kutentha shrink chingwe zowonjezera

20kV kutentha-shrinkable chingwe Chalk Chalk mndandanda mankhwala, oyenera 12/20kV, 18/24kV single-pachimake, atatu-

core polyethylene ndi cross-linked polyethylene magetsi zingwe, seti madzi, kulamulira nkhawa, chishango,

Insulation mu chimodzi. Ndi zinthu zabwino zamagetsi ndi zamakina, zitha kugwiritsidwa ntchito m'malo osiyanasiyana ovuta

mikhalidwe kwa nthawi yayitali. Iwo ali ubwino kuwala kulemera ndi unsembe zosavuta. Amagwiritsidwa ntchito kwambiri mumagetsi

mphamvu, mafuta, mankhwala, zitsulo, njanji, doko ndi zomangamanga ndi zina
