Mechanical Industry Standard of the People's Republic of China
YA-W, YA-WF1 series outdoor, outdoor corrosion-resistant and increased safety three-phase asynchronous motors (frame size 80~280) 1 Subject content and scope of application
JB6763--1993
This standard specifies the types, basic parameters and dimensions, technical requirements, test methods, inspection rules and marking and packaging requirements of YA-W, YA-WF1 series outdoor, outdoor corrosion-resistant and increased safety three-phase asynchronous motors. This standard applies to YA-W, YA-WF1 series outdoor, outdoor corrosion-resistant and increased safety three-phase asynchronous motors (frame size 80~280) (hereinafter referred to as motors).
The explosion-proof performance of this series of motors meets the requirements of GB3836.3, and the explosion-proof marks are eIT1, eⅡT2, and eIT3. The protection type complies with the provisions of ZBK04003. The special environment codes are W and WF1. Both are suitable for chemical, petroleum, petrochemical and other industrial environments with explosive mixtures of groups T1 to T3 indoors and outdoors. Type W is suitable for environments with slightly corrosive media. Type WF1 is suitable for environments with medium and lower corrosive media.
