Yb3-355L1- 185kw 750rpm Explosion-Proof Three Phase Asynchronous Electric Motor

The YB3 series motors with high strengh cast iron structure,have the characteristics of high efficiency,high reliability,beautiful apperance,low noise,little vibration,and can be applied to a variety of equipments installed in explosion environment of petroleum,chemical,coal,power plant,metallurge fan,such as fan,pump,compressor and so on. YB3 series flameproof type three-phase asynchronous motor is our upgraded explosion-proof motor basic series from YB2 series,the series motor's power level,installation dimensions comply with IEC standard,with coincident corresponding relationship with German standard DIN42673,It is conducive for the export equipment matching and introduction of spare parts for equipments.
For ExdIMb,equipment installed at coal mine methane explosive environment,has "high" protection level.This level has sufficient safe performance,it cause impossibility to be the ignition source during equipment normal running,or under expected failure conditions for the period between gas suddenly appeared and equipment power off,it is applicable for electrical equipment for non excavation working face. Exd II AT4Gb,Exd II B T4 Gb are applicable for equipments with explosive gas environment except coal mine,with "high" protection level,it is not a source of ignition during normal running or under expected fault conditions.
