| The above dimensions are made of aluminum alloy. If it needs custom-made, it can be Steel plate welding or stainless steel. |
Application:
1. Can be used in hazardous areas: Zone 1 and Zone 2 .
2. Can be used in explosive gas atmospheres of Category IIA and II B IIC where the temperature classification is T6.
3. Two type of Ex d(IIB) and complex(IIC).
4. Flammable dust atmosphere.
5. Widely using in the fields of oil, chemical industry , spaceflight ,war industry and so on.
The gas field is divided into three areas: Zone 0, Zone 1 and Zone 2:
Zone 0: A site where explosive mixtures in an explosive atmosphere occur continuously in the form of gases, vapors or mists or exist for long periods of time.
Zone 1: A site where explosive mixtures of gas, vapour or mist may occur in an explosive atmosphere during normal operation. Zone 1 is a typical application site for explosion-proof electrical equipment.
Zone 2: In normal operation, explosive mixtures in the form of gases, vapors or mists are unlikely to occur in explosive atmospheres, and if present, are only occasional and short-lived locations. Usually, "short time" means that the duration is no more than 2 hours.
