How to Properly Utilize Fireproof Bridge Beams?

Fire-resistant cable tray demand closed; the cover must not be left open to maintain fire protection. Fire-resistant trays are suitable for power cables below 10KV, as well as control cables, lighting wiring, and overhead cable conduits for indoor and outdoor installations. Briefly, fire-resistant trays are composed of a fire-resistant board made from glass fiber reinforced materials and inorganic binder, combined with a metal frame and other fire-resistant materials.

The outer layer is coated with fire-resistant paint, ensuring that the fire-resistant bridge trays will not ignite upon exposure to fire, thereby effectively preventing the spread of flames. It boasts excellent fire-retardant properties, as well as resistance to heat, oil, and corrosion. The installation process is convenient, with a reasonable structure and a long service life. Moreover, it is aesthetically pleasing. Cables are installed within the cable bridge trays.

The environment is clean and sweeping is convenient. The fire-retardant coating features a thin coating, high耐火limit, and strong adhesion. The fire-retardant bridge supports achieve their fire-resistant effect by applying a layer of fire-retardant paint to the surface of standard bridge supports! In reality, the bridge supports themselves do not catch fire.

Fire can only be ignited by the flame-retardant principle of the flame-retardant paint on cables. The protective thickness of the flame-retardant bridge supports, as required by Table 10 of "J control distribution power cable bridge," is as follows: electroplated >12μm, hot-dipped >65μm, sprayed plastic >50μm, and flame-retardant >500μm, which can be measured by a thickness gauge.
