EXB型不燃电缆桥架由无机不燃材料制成，该产品具有不燃、耐腐蚀、耐油、耐火、质轻、施工方便等优点。EXB-3型复合型防火桥架由无机与有机难燃材料复合制成，它综合了有机和无机系列产品的优点，弥补了有机系列成本高、耐火时间短和无机系列耐火候性存在的缺陷，具有难燃、耐火、耐油、耐腐蚀、重量轻、强度好、施工方便等特点。适用各型电缆的空中敷设，特别适合中等以上腐蚀环境，克服了钢质电缆桥架不防火、易腐蚀等缺点，是特定敷设环境中钢质电缆桥架的理想替代产品。
Type EXB non-flammable cabletrayis made of inorganic non-flammable materials and is non-flammable, light, highly corrosion-, oil- and fire-resistant and easy in construction. Type EXB-3 composite fireproof cable tray made of both the inorganic and the organic non-flammable materals combines the merits of the inorganic and organic series products and eliminates the weaknesses of the organic series of high cost and short fire-resisting duration and that of the inorganic series poor weather-resistance.l It is non-flammabhle, light and easy in construction and has the high strength and the good oil-, corrosion- and water-resistance. It is suitable for aerial laying of cable, especially under moderate or more serious corrosive environment and it will eliminate the weakness of the steel tray such as non-fireproof and corrosion, thus it is an ideal substitute for steel cable tray under special laying environments.
