20000 insulator hamwe na 25000 Kurwanya umwanda (kabiri-isuka) Ihagarikwa rya farashi Insualtorsex yoherejwe muri Amerika ya ruguru iri gukorwa

Ubu uruganda rukora insuliranteri ya disiki hamwe na insulator zirwanya umwanda (inshuro ebyiri), kandi umusaruro ukorwa ni ukwezi kumwe

Tegura amazi ya glaze

gupima ibikoresho fatizo byujuje ubuziranenge ukurikije igipimo cya elegitoroniki ukurikije ibisabwa, uvange ibikoresho fatizo, hanyuma uvange ibikoresho bibisi neza kugirango urebe neza kandi bitondekanye neza.
