Definition of explosion-proof grade of explosion-proof electric actuator: The classification of explosion-proof grade of explosion-proof electrical equipment is based on the type of equipment used, the temperature group of explosive gas mixture, and the explosion-proof type of explosion-proof electrical equipment. Explosion-proof electrical equipment can be divided into two categories: one is underground electrical equipment in coal mines; the other is electrical equipment used in places other than mines.

Explosion-proof electric actuator: The shell is made of hard aluminium alloy, which is anodized and coated with polyester powder. It has strong corrosion resistance. The protection grade is ip67, NEMA4 and 6, and has IP68 type for selection. Fully enclosed squirrel cage motor, small size, large torsion, small inertia force, insulation level f, built-in thermal protection switch, can prevent damage to the motor.
