EXA型/EXA-3型电缆用封闭式防火槽盒
Type EXA /Type EXA-3 Closed Fireproof Cable Trough Box<点击图片放大> EXA电缆用无机防火槽盒由无机不燃材料制成，EXA-3复合型防火槽盒由无机和有机难燃材料复合制成，适用于各种电压等级电缆的防火保护和耐火分隔，能有效地阻止火灾的蔓延和扩散。具有耐腐蚀、耐油、耐水，强度高，安装简便等优点。适合于潮湿、含盐雾、化学气体、严寒、酷热等多种环境条件下使用。可广泛应用于电力、冶金、石化、邮电通讯等行业电缆密集场所。 Type EXA inorganic fireproof trough box is made of the inorganic non-flammable materials, and type EXA-3 composite fireproof trough box is compounded with both the inorganic and the organic non-flammable materials. They are used in firproof protection and fireproof isolation for cables of various voltage classifications to effectively inhibit fire propagation and spread. Due to their high oil-, corrosion- and water-resistance, good strentgh and simple erection, they are suitable for the wet, cold, and hot environment or other serious environments containing salt fog or chemical gasses and are widely applicalbe in cable-closely-arranged places in many fields such as electrical power, petroleum chemicals and post and telecommunicatin.主要技术性能Main technical performances项目
