三、BBD粉塵防爆標志燈性能特點
1. 鑄鋁合金外殼，表面噴塑；
2. 標志顏色均為綠色，銹導標志可由用戶選擇，標志圖案可根據用戶要求設計；
3.電子發光板式, 采用特有的壓電效應, 在正常工作時幾乎不耗電, 應急時間1.5小時以上, 降低了運行費用;
4. 內裝免維護鎳鎘電池組，在正常供電下自動充電，事故或停電時應急燈自動點亮；
5. 鋼管或電纜布線均可;
6. 符合GB3836-2000、IEC60079、GB12476.1-2000、IEC61241標準要求。 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.
