BAYD隔爆型标志灯(ⅡB) BAYD Flame-proof type, Marker-indicator Lamp (ⅡB)

1. 性气体环境危险场所：1区、2区； 2. 可燃性气体、蒸气级别：ⅡA、ⅡB； 3. 温度组别：T1~T6; 4. 可配装U型荧光灯、碘钨类和电子发光板。 1. For the dangerous sites with explosive air mixture: 1 division, 2 division; 2. Flammable gas, steam class: ⅡA、ⅡB; 3. Temperatures classification: T1~T6; 4. Access to fit U-haped fluorescent lamp and iodin tungsten light, and Electronic luminescence board.   1. 铸铝合金外壳，表面喷塑； 2. 标志颜色均为绿色，锈导标志可由用户选择，标志图案可根据用户要求设计； 3. 电子发光板式, 采用特有的电压效应, 在正常工作时几乎不耗电, 应急时间1.5小时以上, 降低了运行费用; 4. 内装免维护镍镉电池组，在正常供电下自动充电，事故或停电时应急灯自动点亮； 5. 钢管或电缆布线均可; 6. 符合GB3836-2000、IEC60079、GB12476.1-2000、IEC61241标准要求。 1. Diecasted aluminium alloy shell with plastic-sprayed surface. 2. The transparent mark-plate can be chosen and matched to users requirement. 3. Electronic luminescence board type, uses special piezoelectricity effect, under the normal, it hardly consume the fime it can last several hours in the emergency meanwhile, need no maintenaince and reduce the operation cost use. 4. Under the normal power-supplying condition, the inner nickel-cadmium can recharge automatically, so that, the emergency lamp will turn on automatically when the power lose because of accident or power failure. 5. Suitable for both steelpipe and cable wiring.. 6. Suitable for GB3836-2000, IEC60079, GB12476.1-2000, IEC61241 standard request. 额定电压(V) Rated voltage 额定功率(W) Rated power 光源 Luminous source 应急照明时间 (min) Emergecy lighting time 防爆标志 Ex-mark 进线口螺纹 (G") Inlets thread 质量 (Kg) Mass 正常照明 Normal lighting 应急照明 Emergent lighting 正常 Normal 应急 Emergent 正常 Normal 应急 Emergent AC220 DC4.5 6 6 U型荧光灯管 U Fluorescent lamp tube 碘钨灯 Iodin-tungsten lamp 90 120 Exd Π BT6 3/4 8 电子发光板 Electronic luminescence board 6
