The explosion-proof three-phase induction motors are designed and manufactured according to National Standard GB3836.1 for "electric apparatuses in explosive gas environments–part 1: general requirement" and GB3836.2 "Electric apparatuses in explosive gas environments–part 2: flameproof enclosure D."

The YBZa-H series of explosion-proof three-phase induction motors is used in hoisting machinery in ships where the temperature class is T1-T4 and flammable gas may be present. This inflammable motor meets specifications for GB3838.1-2 for "electrical apparatuses in explosive gas environments."

The JBZ2-H series of explosion-proof three-phase induction motors have a flame proof performance that meets the GB3838.1~2 "Electrical Apparatuses in Explosive Gas Environments".

The YB3 series of explosion-proof three-phase induction motors are flame-proof motors that meet advanced international standards. These explosion-proof motors feature high efficiency, high locked-rotor torque, low noise and vibration, and reliable operation.

The YB2 series of explosion-proof three-phase induction motors are flame-proof motors that meet advanced international standards.
