Vertical Shaft Fire-Resistant Cable Tray

Shaft fireproof cable tray: A standard cable tray or a fireproof cable tray enclosure with fireproof partitions, coated with fire-resistant paint, can effectively isolate air and achieve thermal insulation. The thickness of the fire-resistant paint should be at least 1mm, which is the general fireproofing effect, with variations in cost between cheaper and more expensive options.

The fireproof cable tray features a steel outer shell, double-layer fireproof covers, and an inorganic fireproof trough inside. The uniform thickness of the thermal insulation layer is 25mm. The double-layer covers allow ventilation and heat dissipation, while the interior is sprayed with fire-resistant paint. In the event of a fire, the paint expands, blocking the heat dissipation holes to protect the cables inside the trough. The inorganic fireproof trough has undergone a fixed耐火检修中央 (fire resistance inspection center) 60-minute耐火试验 (fire resistance test), with no damage to the cables and excellent structural support, effectively securing the inorganic fireproof trough.
