1. N-gun ja ai hygroscopicity nga ai. Fire- hpe ninghkap lu ai cable ni gaw, magnesium oxide zawn re ai mineral insulating arung arai ni hpe lang chye ai, dai ni gaw hka lim ai shara grai law ai hte wan hpe grai kaja hkra ninghkap lu ai. Raitim, mineral insulating materials ni a n-gun n rawng ai lam langai gaw, shanhte a n-gun ja ai hygroscopicity rai nna, nbung kaw na hka hpe hkap la chye ai. Cable langai a insulation layer gaw hka law law hpe hkap la ai shaloi, shi a insulation galaw ai lam hpe hkra machyi shangun na rai nna, dai gaw wan n-gun hte wan n-gun hpe shayawm ya lu ai.
2. Cable a daw nkau mi hpe n-gun n rawng hkra pat da ai. Hka lum ai (sh) hka gaw cable end (sh) cable makawp maga ai layer kaw na cable insulation layer de shang nna, cable a accessory langai hpra de shang wa nna, dai hku nna power system ting hpe hkra machyi shangun na re.
