Sharing dry goods, let you know the characteristics of fireproof bridge in one minute

What are the characteristics of fire-resistant cable trays? Let's take a brief look.

Fire-resistant cable trays are constructed from a sturdy metal outer shell and flame-retardant material inside. The sturdy metal outer shell resists external forces and protects cables from damage. The flame-retardant material encases the cables to prevent them from igniting in the event of a fire. Fire-resistant cable trays are safe and reliable, provide maximum cable protection, and are easy to maintain.

Fire-resistant cable trays are often used in high-temperature environments, fire escapes, and fire-prone environments. Their excellent fire-retardant properties prevent the spread of fire and effectively protect cables within cable ducts. Fire-resistant cable trays can be used to lay wires and cables up to 10 kV, control cables, and lighting wiring in indoor and outdoor overhead cable trenches and tunnels. They have a wide range of applications. Conventional cable trays, however, have limited performance characteristics and are generally used in normal environments. They cannot be used in corrosive, humid, or high-temperature environments. Conventional cable trays can only be used in dry indoor environments and provide poor protection for cables.

What are the differences in the processing of fire-resistant and conventional cable trays? Fire-resistant cable trays are primarily composed of fire-resistant panels made of fiberglass and inorganic adhesives, metal frames, and other fire-resistant materials. Ordinary cable trays are sprayed with fire-resistant materials to achieve a fire-retardant effect, preventing fire damage to the cables within. However, ordinary bridges are less sophisticated and require simpler processing than fire-resistant cable trays.

What are the key points in maintaining fire-resistant cable trays? Let's take a brief look.

As an intelligent low-voltage electrical system, fire-resistant cable trays play an important role in our daily lives. When crossing a section of road in a public passage or outdoors, it is recommended to add padding or use trays under the bottom crosspiece. When crossing a large span across a public passage, the load-bearing capacity of the bridge can be increased or a truss can be selected according to user requirements.

During daily cable tray maintenance, it is important to avoid wiping the exterior of paint, mirrors, and glass with damp cloths or hard objects. Avoid contact with acids, alkaline chemicals, and greasy substances. Maintain good ventilation and avoid placing cable trays in hot and humid locations. Avoid contact with corrosive liquids such as alcohol and nail polish.

Daily Maintenance: Regularly wipe away dust from the surface with a clean, soft cloth.

Regular Maintenance: Wipe the exterior evenly with a special wax polish. After a while, polish with a clean, soft cloth to ensure smooth rotation and prevent rust and oxidation. Quarterly, as usual, perform focused maintenance. Hardware and metal handles can be wiped dry with a light oil to prevent moisture. After wiping away dust with a soft cloth, you should use a clean, soft cloth and special maintenance wax.
