Umehluko Phakathi Kwezinga Lobufakazi Bokuqhuma BT1 kanye ne-BT4

Zombili izinto zilinganiselwe njenge-IIB ukuze zivikeleke ekuqhumeni, ezihluka kuphela ngezinga lokushisa kwazo.

Iqembu lokushisa lemishini kagesi	Izinga lokushisa eliphezulu elivumelekile lempahla kagesi (℃)	Izinga lokushisa legesi/umhwamuko (℃)	Amazinga okushisa edivayisi asebenzayo
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

Amagama athi T1 kuye ku-T6 abonisa izinga lokushisa eliphezulu elivumelekile endaweni yokusebenza ngaphansi kwezimo ezithile, iyancipha kancane kancane. Amazinga okushisa aphansi asho ukuphepha okuphezulu.

Ngenxa yalokho, BT1 has a slightly lower explosion-proof rating compared to BT4.
