I-Explosion-Proof Level BT2 ne-BT4

Isigaba se-dⅱ bt4 sokuvikela ukuqhuma kwempahla kagesi sidlula u-dⅱ bt2, zihluka kuphela ngezinombolo zokuhlukanisa 4 futhi 2.

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

Isigaba T4 sicacisa ukuthi izinga lokushisa legesi lingaphansi kuka-135°C, kuyilapho i-T2 ivumela izinga lokushisa elifinyelela ku-300°C.

Amazinga okushisa okushisa ahlukaniswe izigaba eziyisithupha, kusuka ku-T1 kuya ku-T6, with each higher category being suitable for the conditions of all preceding categories.
