三、BBD粉尘防爆标志灯性能特点
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, 采用特有的压电效应, 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.
