Diecasted aluminiumalloy shell with plastic-sprayed surface.
The transparent mark-plate can be chosen and matched to user’s requirement.
The electronic uminescence boardtype,uses special piezoelectricityeffect.
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.
Under the normal power-supplying condi tionm the inner nickel-cadmium can
recharge automatically,so that,the emergency lamp will tum on automatically
when the power lose because of accident or power failure.
Suitable for both steelpipe and cable wiring.
Suitable for GB12476,IEC61241 standard request.
