YB2 series explosion-proof three-phase asynchronous motor
¡öProfile

¡¡¡¡Aiming at the level of international advanced explosion-proof motor series made by GERMANY SIEMENS COMPANY,YB2 series explosion-proof three-phase asynchronous motor is the basic explosion-proof motor product that is developed by combining current market and domestic explosion-proof motor industry,and is also the new generation product of YB series.
¡¡¡¡This series of motors have the explosion-proof performance meeting the regulations of GB3836.1-2000¡äpartl:general requirement of electrec equipment applied under the condition with explosive gas¡ä,GB3836.2-2000¡äpart2:explosion-proof'd'of electric equipment applied under the condition with explosive gas¡ä,IEC79-1 and DIN EN50014¡«50020,and use the explosion-proof marks of Exd¢ñ,Exd¢òAT4 and Exd¢ò BT4,thus are applied at the location with explosive gas compound,and the Exd¢ñ is applied in the non-excavation working condition and the coal mine with mehtane or coal dust,the Exd¢òAT4 and Exd¢ò BT4 are applied in the condition of explosion-proof gas compound with Factory¢ò type,Grade A,B and the temperature T1,T2,T3 and T4.Basing on YB2 basic series motor,we may derive it into many kinds of explosion-proof motors such as YB2-W outdoor type,YB2-WTH outdoor humid & tropic type etc.
