Fireproof trough box board
Fireproof trough box is a new generation of fireproof product successfully developed by our company. It is mainly made of glass fiber reinforced materials and inorganic binders. Tested by the National Academy of Building Research and the Hebei Fire Science Research Institute of the Ministry of Public Security, the quality meets regulatory requirements.
Product Features: It will not burn when exposed to fire, thereby blocking the spread of fire heat. It has extremely good fire-retardant and fire-retardant effects. It is water-resistant, oil-resistant, corrosion-resistant, non-toxic and pollution-free. It has good machinability and can be sawed, drilled, Planing and other mechanical processing, long service life The cable is installed in the trough box, the environment is clean and easy to clean
Application scope is generally used for fire-retardant separation in overhead cables, cable tunnels, cable mezzanines, cable shafts and other cable-dense places. To achieve the purpose of preventing cable fire and flame extension and fire prevention (or fire retardant) separation of important cable circuits. Among them, inorganic fireproof tank boxes are recommended for use in indoor dry environments. The composite fireproof tank box is particularly suitable for use in areas with humidity, salt spray, chemical gases, severe cold, extreme heat and other environmental conditions.

Precautions
①. The connection between the tank cover and the tank box body should be tight, and connectors should be used during installation to prevent loosening.
②. Fire-retardant separation should be applied at both ends of the trough box and at appropriate intervals in the longer trough box. Generally, it is advisable to use the special fireproof bag produced by our factory for sealing.
