Heerka Caddeynta Qarxa Keebaa Sare, BT4 ama BT6

Marka loo eego heerarka qaranka ee ilaalinta qaraxa korantada, BT4 iyo BT6 labaduba waxay hoos yimaadaan fasalka IIB.

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

Si kastaba ha ahaatee, the ‘T’ classification pertains to the temperature rating of explosion-proof electrical devices. Aaladaha lagu sifeeyay T6 waa in ay ilaaliyaan heerkulka sare oo aan ka sarreyn 85°C, T5 waa in aanu dhaafin 100°C, and T4 must not surpass 135°C.

The lower a device’s maximum surface heerkulka, the less likely it is to ignite atmospheric gases, thereby enhancing safety. Sidaa awgeed, the explosion-proof rating of BT6 exceeds that of BT4.
