Heerka Caddeynta Qarxa Keebaa Sare, CT4 ama CT5

Exd IIC T4 iyo Exd IIC T5 ayaa wadaaga qiimaynta caddaynta qaraxa, iyada oo la kala sooci karo kaliya heerkulka ugu sarreeya ee mid kastaa uu gaari karo inta lagu jiro hawlgalka.

Kooxda heerkulka qalabka korontada	Heerkulka ugu sarreeya ee la oggol yahay ee qalabka korantada (℃)	Heerkulka dabka gaaska/ uumiga (℃)	Heer kulka qalabka lagu dabaqi karo
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

Heerkulka dusha sare ee ugu badan ee la ogol yahay way kala duwan yihiin: ee Exd IIC T4, waa 135 darajo Celsius, halka Exd IIC T5, it is capped at 100 darajo Celsius.

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