Yeyiphi iNqanaba loBuqhushumbo-bubungqina obuphezulu, CT4 okanye CT5

I-Exd IIC T4 kunye ne-Exd IIC T5 zabelana ngomlinganiselo ofanayo wobungqina bokudubula, kunye nokwahlula okukuphela kweqondo lokushisa ngalinye linokufikelela ngexesha lokusebenza.

Iqela lobushushu lezixhobo zombane	Ubushushu obuphezulu obuvumelekileyo bezixhobo zombane (℃)	Irhasi/ubushushu bokutshisa (℃)	Amanqanaba obushushu besixhobo esisebenzayo
T1	450	＞450	T1~T6
T2	300	＞300	T2~T6
T3	200	＞200	T3~T6
T4	135	＞135	T4~T6
T5	100	＞100	T5~T6
T6	85	＞85	T6

Ubuninzi obuvumelekileyo bobushushu bomphezulu buyohluka: ye Exd IIC T4, yi 135 Izidanga zeCelsius, kanti Exd IIC T5, it is capped at 100 Izidanga zeCelsius.

Given that lower operating temperatures enhance safety, the explosion-proof classification CT5 is considered superior to CT4.
