F.R.C-4A耐火母线槽系统

F.R.C-4A耐火母线槽    F.R.C-4A Busbar Duct System 

本产品采用耐高温云母带绝缘材料保证导电母排电气绝缘性能，外壳表面处理采用两层防火涂料进行底喷和面喷，此种防火涂料通过高温火焰幅射后，能生成一层30~50mm厚的泡沫状保护层，对母线槽外围进行保护，起到隔热作用，保证外壳不直接烧坏。从而确保母线槽系统在发生火灾后正常工作。

本产品在正常条件下电气性能完全等同于普通其它型号母线槽，订货参照F.R.C-4A防火母线槽的技术参数和电流等级。安装结构形式与其它母线槽相同，请予参照选型。

This product is adopted the high-temperature resistant mica insulation material to ensure the electric insulation perfor-mance of the electric conductive venter plate.The surface treatmnet of the shell is bottom and surface sprayed with double coatsfire proof paint which can form a spumescence protection coat after the high temperature blaze radiation,to protect the bus ductand indulate heat and to ensure that the shell will not burnt directly,then the bus duct system can work normally atter fire-happens.

Under normal conditions,the electric performance of the product is equal to other ordinary types of bus duct,please placeorder according to the technology parameters and current grade of the F.R.C 4A fire-resistant bus duct.The installation type issame as KFM bus duct,please select accordingly.
