Molded cable bracket FRP cable bracket L250mm FRP composite bracket

Product Introduction With the rapid development of my country's economy, the requirements for urban beautification and power supply safety are also increasing. Therefore, cable tunnels and cable trenches have also become the main channels for urban power supply. For a long time, cable brackets made of angle iron have been used to erect cables. Angle iron brackets are usually made of angle iron profiles that are welded or assembled with fasteners. The production process of traditional angle iron brackets consumes a lot of energy, involves multiple processes and takes a long time, and the product quality cannot be guaranteed. Angle iron brackets are easily corroded when used in many harsh environmental conditions, such as subway tunnels, chemical industries, rainy and humid environments, or coastal salt spray. The maintenance costs of the facilities are high and the service life is short. In terms of anti-rust and anti-corrosion, although external painting or hot-dip galvanizing and other technologies are currently used, it still cannot fundamentally solve the rust problem, seriously affecting the safety and trouble-free service life of power communication facilities.
The latest successfully developed fiberglass cable trench bracket by our factory is developed to overcome the shortcomings of metal cable brackets and inorganic material cable brackets. In this innovation, on the one hand, we listened to the opinions of many experts and users, brainstormed and conducted repeated research; on the other hand, we reviewed the development trends of electric and non-electric brackets at home and abroad, condensed the advantages of existing brackets for other purposes, and developed unique ideas with our own characteristics. Highlight product functionality throughout. Bold development and innovation finally developed a fiberglass cable trench bracket that is suitable for different regions, different conditions and different development needs, has superior electrical insulation properties, anti-corrosion properties and flame retardant properties, good strength, high strength and easy installation.
Two basic properties
High strength and good designability
FRP is mainly composed of glass fiber for reinforcement and thermosetting resin for bonding and load transmission. The tensile strength of glass fiber is very high, and its content, length and laying form determine the strength of the stent product.
The strength of thermosetting glass fiber reinforced composites can range from Therefore, we can design the amount, length and laying form of glass fiber according to the product's stress, production process, price affordability.
No creep
The rigidity of the fiberglass cable trench bracket is twice that of the fiber reinforced bracket produced by a company in the United States. Even under long-term load, it will not deform or tilt downward like the metal cable brackets used in subways in some domestic cities.
Fire protection
Oxygen index is an important detection method for evaluating cable fire products. Oxygen index refers to the burning resistance of fire-resistant products under maximum oxygen conditions. The use in engineering should be determined according to the burning intensity. For example, under the conditions of a single cable, if a cable ignition accident occurs within a short period of time, high-temperature heat accumulation above 10°C will occur, causing the cable to ignite along its direction. The more cables there are in densely packed areas, the greater the mass of the combustible material. The mass of the combustible body per unit length when using a cable is / Now calculate the mass of the combustible body per unit length using a cable as / Calculate the oxygen index based on the maximum possible combustion intensity and should not be less than. We believe that the oxygen index in product fire protection standards is more appropriate.
According to the requirements of use, the oxygen index of the fiberglass cable trench bracket we developed is greater than or equal to. It meets the safety requirements of fire protection, low smoke, halogen-free and non-toxic. The fireproof performance is higher than the technical specifications of fiberglass plastic cable trough plates used in Taiwan's underground railways and is much higher than the reinforced thermoplastic brackets of a company in the United States. This indicator is no lower than the British-certified fire protection standard for composite materials used in new vehicles of the Hong Kong MTR.
Corrosion Resistance
The fiberglass cable trench bracket is corrosion-resistant and is especially suitable for use in humid salt spray acid and weak alkali environments.
Electrical insulation
The insulation performance can be adjusted according to the usage requirements.
) The insulation resistance of the electrically insulating type is greater than
) The surface resistance of the antistatic type is less than.
Easy to use
Can be installed with pre-embedded screws or expansion screws. Greatly reduces the labor intensity of employees.
Service life
Years underground and above ground.
Three Instructions for Use
Select the bracket specifications according to the net width of the cable trench and cable channel and the size of the cable model. The outer diameter of the cable used by the heavy-duty bracket is not larger than 1 mm. The outer diameter of the cable used by the light-duty bracket is not larger than 1 mm. If there are special requirements, the supply and demand parties can negotiate and determine according to the actual situation.
Suitable temperature range for the environment.
The installation should be horizontal. If it is tilted, other measures must be taken to fix the cable.
The bracket is fixed with bolts or expansion screws and is pre-embedded to a depth of mm.
It is required to balance the horizontal spacing of vertical supports on the same side in centimeters and stagger the installation of double-sided supports to ensure balanced load-bearing of the supports.
The fixed wall surface must be flat to ensure that the stress-bearing area of the base avoids distortion. When laying cables, it is better to lay them from top to bottom. When laying and dragging cables, they should drag them horizontally.
