Explosion -proof steel wire rope electric courier is suitable for workshops, warehouses and other places with flammable and explosive mixtures to do general transportation work. It is suitable for explosive mixtures containing combustible gases, steam and air. It has the advantages of structured compactness, self -weight, small volume, and large lifting ability.
The working environment of explosion-proof electric gourds: Explosion-proof steel wire rope electric gourd is generally indoor work, the working environment temperature is -20 ~+40 ° C, the relative humidity is not more than 90%(when 25 ° C), and the altitude is not more than 1000m. When the altitude exceeds 1000m and the working environment temperature exceeds 40 ° C, it shall be implemented in accordance with the regulations of the GB755. The environmental environment of explosion -proof gourd should have good ventilation facilities. The explosion -proof hazard area used in explosion -proof gourds is area 1 or 2. (Area 1: The environment of explosive gas mixture may occur during normal runtime. Area 2: The environment of explosive gas mixture cannot occur during normal runtime, even if it appears, there is only an environment in which explosive gas mixtures are existed in short -term).
Electrical explosion -proof requirements for explosion -proof electric gourds: The electrical equipment selected by explosion -proof gourds should meet the relevant requirements of GB3836, and should also have the qualified certificate of explosion -proof inspection issued by the national explosion -proof inspection unit within the validity period. The explosion -proof standard should not be lower than the corresponding requirements of the host ; The connection between explosion -proof gourds and the power cord between explosion -proof electrical appliances should be used with heavy crushing core cables, and a core ground wire should be used. Installing connection cables must meet explosion -proof requirements. There is no connector in the middle of the cable. If necessary, there should be an explosion -proof wiring box. All electrical components must not be naked.
