6. I-High-Voltage Insulation:Izivamvo ezikufutshane neemagnetron okanye iisekethe ze-HV kwii-microwaves kufuneka zifakwe i-insulation ukuze zimelane nombane ophezulu onokubakho (umz., iikhilovolthi) ukunqanda ukophuka.
7. IMicrowave Interference Resistance / Non-Metallic Design (Ngaphakathi kwiCavity yeMicrowave):
   • Okubalulekileyo!Izivamvo ezivezwe ngokuthe ngqo kumandla e-microwavemayingabi nentsimbi(okanye iinxalenye zentsimbi zifuna ukhuselo olukhethekileyo), kungenjalo i-arcing, i-microwave reflection, i-overheating, okanye umonakalo wemagnetron ungenzeka.
   • Ngokuqhelekileyo sebenzisaizifudumezi ezifakwe ngokupheleleyo ngeceramic (NTC), okanye ugxumeke iiprobe zesinyithi ngaphandle kwesikhokelo/ikhaka, usebenzisa izikhondaktha ze-thermal ezingezizo ezentsimbi (umzekelo, intonga yeceramic, iplastiki yobushushu obuphezulu) ukuhambisa ubushushu kumngxunya womgodi.
   • Iilothe zikwafuna ingqwalasela eyodwa ekukhuseleni nasekuhluzeni ukuthintela ukuvuza okanye ukuphazamiseka kwamandla e-microwave.
8. Uyilo lwe-EMC:Iinzwa kunye nezikhokelo akufanele zikhuphe ukuphazamiseka (i-radiated) kwaye kufuneka zixhathise ukuphazamiseka (i-immunity) ukusuka kwamanye amacandelo (i-motors, i-SMPS) yokuhambisa umqondiso ozinzile.
