Explosion-proof Motor(HV)

Explosion-proof motors used in the oil&gas industry must be highly durable and performance-driven, given the environments in which they are installed, where flammable gases exist. Hyosung Heavy Industries' lineup of explosion-proof motors adheres to major international standards (e.g. IECEx, ATEX, UL, CSA, GOST, KGS).

Features
Ex d
(flame-proof enclosure)		 The pressure-resistant structure of our explosion-proof motors is designed to withstand the force generated by an explosion of gases or vapors inside the container. Additionally, the motor is constructed in such a way that flammable gases or vapors from the outside cannot be ignited via joints.
Ex p
(pressurized enclosure)		 To prevent explosive gases or vapors from entering the container, the motor structure pressurizes protective gas (such as air or non-flammable gas) into the container, thereby maintaining its internal pressure.
Ex e
(increased safety)		 Our explosion-proof motor is designed with increased safety measures in terms of both its mechanical and electrical structures as well as temperature rise in order to prevent electric sparks, arcs, or high temperatures from becoming sources of ignition for flammable gases or vapors during normal operation.
Ex n
(non-incendive)		 The structure is designed to prevent the ignition of surrounding flammable gases or vapors during normal operation.
Scope of Production
Pole Max Power Max Frame
Ex d
(flame-proof enclosure)		 ~ 20P ~ 4,000kW ~ 800Fr.
Ex p
(pressurized enclosure)		 ~ 20P ~ 13,000kW ~ 1,500Fr.
Ex e
(increased safety)		 ~ 20P ~ 13,000kW ~ 1,500Fr.
Ex n
(non-incendive)		 ~ 20P ~ 13,000kW ~ 1,500Fr.
