YB2系列高压防爆型三相电动机（H355~560),是我公司吸取国内外同类电机的优点并采用新材料，新工艺制成的新产品。符合GB3836.1-2010《性环境 第1部分：设备通用要求》和GB3836.2-2010《性环境 第2部分：由隔爆外壳“d”保护的设备》的规定、GB3836.3-2010《性环境 第3部分：由增安型“e”保护的设备》，同时隔爆型电动机隔爆结构参数参照IEC60079-1《电气设备隔爆外壳的结构与实验》和EN50018 《性环境用电气设备“d”》标准。

YB2 series high voltage explosion proof motors are new products ,manufactured bu our company with new material and technology on the advantage of similar domestic and international motors.Conbbbb to the provisions of GB3836.1-2010 Explosive atmospheres enclosures-part1:Equipment General requirements GB3836.2-2010 Explosive atmospheres-part2: Equipment protection by flameproof enclosures “d” and GB3836.3-2010 Explosive atmospheres-part3:Equipment protection by increased safety“e”。In additional,the bbbbbeters of their flameproof construction are based on the standard on IEC60079-1 Construction and Test of Flameproof Enclosures of Electric Apparatus and EN50018 Electric Apparatus “d” for explosive atmospheres.

该系列电机具有外形设计美观、力能指标高、可靠性强、体积小、震动小、噪声低、高效节能等特点。

This series of motors are characterized by artistic shape design,high power index,excellent reliability,small size,little vibration,low noise and high efficiency etc.

在YB2基础上派生的户外（W)、湿热带（TH)、户外湿热带（WTH)、防腐蚀型（F1、F2、WF1、WF2)，也可根据国家标准GB/T7060《船用旋转电机技术要求》派生船用YB2-H 系列隔爆型三相异步电动机，其性能指标。安装和外形尺寸与基本系列相同。

Based on YB2 series,the motors can be manufactured for special environments,such as outdoor bbbbbbbbs(W type),tropical humidity (TH type),outdoor tropical humidity (WTH type) and anti-corrosion types (F1,F2,WF1 and WF2).Similarly,YB2-H series flameproof three phase asynchronous motors in ships are also available to national standard GB/T7060 General specifications for rotary electrical machines in ships,with the same perbbbbance indicators,installation and overall dimension as the basic series.
