Description

Technical Field

They have excellent heat insulation, fire resistance, non-combustibility, non-explosiveness, water resistance, oil resistance, chemical corrosion resistance, weather resistance, non-toxicity, good mechanical strength, light weight, high load-bearing capacity, and safety and reliability. The trays are lined with heat-insulating blocks or plates, and the two ends and joints are sealed with fire-resistant materials to ensure that a fire-resistant section is formed after the cover is closed. Even if the cable inside the tray catches fire, the limited air inside the tray will prevent the fire from spreading.
