Summary of fire box

Summary of fire box 

We may not be very familiar with the cable tray. Common tray frames are grid cable tray, steel cable tray and so on.

The fireproof slot box has the characteristics of good heat insulation, fire prevention, no explosion, no combustion, oil resistance, water resistance, chemical corrosion resistance, good weatherability, non-toxic and mechanical strength, large bearing capacity, light weight, safety and reliability. The firebox is easy to install, and can be machined for sawing, drilling and planing. It is suitable for the fire isolation of cable laying. It is an ideal material to effectively prevent flame from burning when the cable is ignited.

For different use, fire box box can be divided into:

1) fire resistant fully closed slot box: applicable to the power cable below 10KV, and the laying of the overhead cable trenches and tunnels in the indoor and outdoor areas, such as control cables and lighting wiring.

2) fire-resistant semi closed slot box: it can be cured by flame, and the temperature in the slot can be limited to the allowable value of the safe operation of the cable. The cover is a double cover plate. In addition to the function of rain proof, it can fall automatically in the case of high temperature, cover the heat dissipation hole and cut off the air.

3) fire box box for cable tunnel: it can be widely used in tunnels, underground public facilities and other occasions. Have good ventilation, when the slot box fire or cable overheating, due to the role of the original open flame ventilation mesh dipped with special fireproof coating plugging, and expansion into thick carbide layer clad cable, on-line automatic small cap the whereabouts of surface covered network, make self extinguishing medium oxygen combustion.

4) refractory inorganic tank box: made of inorganic material and reinforced glass fiber, and the fire resistant structure is totally closed, which effectively prevents the cable from spontaneous combustion and the harm of external fire. Also because of the selection of inorganic materials, it is especially suitable for severe acid and alkali corrosion.
