۳. Explosion-resistant Product installation site There is no corrosive gas to aluminum gold.
Performance Features:
۱. Explosion-proof form: Explosion–a component that generates a spark arc when the equipment is in operation is isolated from the explosive environment, and the explosive shell can withstand the pressure generated by the internal explosion and, conversely, the explosion spreads outside the shell.
۲. Explosion-proof mark: EXdllBT۱~T۴
۳. Protection class: IP۶۵
Iv. electrical Interface: Conventional—M۲۰X۱.۵ custom-G۱/۲
۵. Pick up the cable: ۱۰±۱mm, the field use should tighten the outlet bolt ۲۰, so that the cable seal ring ۱۸ tightly hold the cable to prevent gas infiltration.
