Type EXA anic fireproof trough box is made of the anic non-flammable materials, and type EXA-3 composite fireproof trough box is compounded with both the anic 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 municatin.
