State Grid High Flame-retardant Fireproof Cable Tray, Corrosion-resistant and Easy to Install
The State Grid fireproof cable tray is an important fireproof device used for cable laying in the State Grid system. It has excellent properties such as heat insulation, fire resistance, non-combustibility, water resistance, oil resistance, and chemical corrosion resistance, which can effectively ensure the safe operation of cables.
Material characteristics:
Common materials include polyester fiber reinforced plastics, glass fiber reinforced plastics, steel, and aluminum alloy, etc.
The polyester fiberglass cable tray is lightweight, facilitating installation and transportation. Meanwhile, it has good corrosion resistance and high mechanical strength.
The cable tray made of fiberglass material has strong corrosion resistance, weather resistance, and good insulation performance, making it suitable for harsh natural environments.
Metal materials such as steel and aluminum alloy provide higher strength and durability.
Functions:
Fire isolation: Prevent the spread of flames and smoke when the cable catches fire.
Cable protection: Protect cables from external fire sources and environmental factors.
Self-extinguishing function: In case of a fire, some models can extinguish the flames due to oxygen deficiency through the enclosed structure.
Applicable scenarios:
Cable laying projects of the State Grid
Places with dense cables, such as cable tunnels, cable interlayers, and cable shafts
Indoor and outdoor overhead cable trenches
Places with high fire protection requirements.
