Ubwino wa ma insulators a galasi:

Chifukwa champhamvu yamakina apamwamba pamwamba pa insulator yagalasi, pamwamba pamakhala ming'alu.Mphamvu yamagetsi yagalasi nthawi zambiri imakhala yosasinthika panthawi yonseyi, ndipo ukalamba wake umakhala wocheperako kuposa wa porcelain.Choncho, magalasi insulators makamaka kuchotsedwa chifukwa cha kudzivulaza, zomwe zimachitika m'chaka choyamba cha ntchito, koma zofooka za insulators zadothi zimangogwira ntchito kwa zaka zingapo Pambuyo pake anayamba kupeza.

Kugwiritsa ntchito ma insulators a galasi kumatha kuletsa kuyesa kwanthawi zonse kwa ma insulators panthawi yogwira ntchito.Izi ndichifukwa choti kuwonongeka kwamtundu uliwonse pagalasi lotenthedwa kumayambitsa kuwonongeka kwa insulator, zomwe ndizosavuta kuti oyendetsa azitha kuzipeza poyang'anira mzerewo.Chombocho chikawonongeka, zidutswa za galasi pafupi ndi kapu yachitsulo ndi mapazi achitsulo zimakhazikika, ndipo mphamvu yamakina ya gawo lotsalira la insulator ndi yokwanira kuteteza insulator kuti iwonongeke.Kuwonongeka kwa ma insulators a magalasi ndi chimodzi mwa zizindikiro zofunika kwambiri zoyezera khalidwe lazogulitsa, komanso ndiye maziko abwino owonetsera malonda pa malonda omwe akuperekedwa panopa komanso kubwereketsa.
