Ladder-type FRP cable trays are a common type of FRP cable trays, featuring unique structural and performance characteristics. The following is a detailed introduction to them:

Structural characteristics

The external structure: The ladder-type FRP cable tray is similar in shape to a ladder, consisting of side plates on both sides and crossbars in the middle. The side plates usually have a certain thickness and strength to support the weight of the entire cable tray and the load of the cables. The crossbars are evenly distributed between the side plates on both sides, serving to fix the cables and enhance the overall stability of the cable tray.

Material characteristics: Mainly made of glass fiber reinforced plastic (FRP). Glass fiber features high strength and high modulus, which can significantly enhance the mechanical properties of cable trays, endowing them with excellent compressive and bending resistance. The resin matrix, on the other hand, has excellent corrosion resistance, insulation and weather resistance, which can protect the glass fiber from erosion by the external environment, and at the same time endow the cable tray with good appearance and processing performance.

Performance advantage

Excellent corrosion resistance: It can resist the erosion of various chemical substances such as acids, alkalis and salts, and is particularly suitable for corrosive environments such as chemical engineering, electroplating and sewage treatment. It can effectively extend the service life of the bridge frame and reduce maintenance costs.

Good insulation performance: It has excellent insulation performance, which can effectively prevent leakage and short circuits between cables, improve the safety of power transmission, and is suitable for places with high insulation requirements, such as substations and distribution rooms.

High mechanical strength: The trapezoidal structure design combined with the high performance of fiberglass reinforced plastic material endows it with high mechanical strength and load-bearing capacity, enabling it to bear heavy cables. Meanwhile, it is less likely to deform or be damaged during long-term use.

Light weight: Compared with traditional metal cable trays, ladder-type FRP cable trays are lighter in weight, making them easier to transport and install. This can significantly reduce construction difficulty and labor intensity, and improve construction efficiency.

Good fire resistance: Some ladder-type fiberglass reinforced plastic cable trays use fire-resistant resins and additives, which give them a certain degree of flame retardancy. This can delay the spread of fire when it occurs, buying time for personnel evacuation and fire rescue.

Attractive appearance: The surface is smooth and the color is uniform. It can be coated in different colors or color masterbatches can be added as needed to make it coordinate with the surrounding environment and have good decorative properties.

Application field

In the industrial field, it is often used in industrial enterprises such as chemical engineering, petroleum, metallurgy, and power to lay various power cables, control cables, and communication cables, providing safe and reliable support and protection for the cables and meeting the high requirements for cable laying in industrial production.

In the field of construction: In commercial buildings, office buildings, residences and other structures, it can be used for cable laying in electrical systems, transporting cables from distribution rooms or distribution boxes to various electrical equipment to ensure the stability and safety of power supply. Meanwhile, its beautiful appearance can also meet the decorative requirements of the interior of the building.

Municipal engineering: In the construction of infrastructure such as traffic tunnels, subways and Bridges in cities, ladder-type fiberglass reinforced plastic cable trays have also been widely applied. It can provide reliable protection and support for the cables of lighting, communication, monitoring and other systems in the tunnel, and adapt to the complex underground environment and the requirements of long-term use.

In the mining field: Due to its corrosion resistance and high strength, it is also widely used in the laying of cables in harsh environments such as mines. It can withstand the moisture, dust and other environmental conditions in underground mines, ensuring the normal operation of cables.
