The cable tray should have measures to prevent the cable from being scratched, such as various bends, tees, four-way, etc., which should be arc-shaped, and the down-pulling device should be used when the cable is down. When the cable tray enters the room from the outdoor (such as substation), it should be sealed, and fireproof plugging and sand sealing can be adopted. At the same time, the glass fiber reinforced plastic bridge should be inclined to the outside, generally with a slope of 1% to prevent rainwater from flowing backwards. Cable bridge has high mechanical strength, which has both the rigidity of metal bridge and the toughness of FRP bridge, and has good corrosion resistance, strong aging resistance, beautiful appearance, convenient installation and long service life. Epoxy resin and epoxy resin composite cable bridge are suitable for use in strong corrosive environment, long span and heavy load conditions.

The FRP bridge adopts the advanced FRP pultrusion process at home and abroad, which is mechanized and continuously produced. Therefore, it not only has the advantages of the bridge produced by domestic peers, but also has stable product size and can be selected at will, and the length can exceed 8 meters, which has higher strength, rigidity and corrosion resistance. Nantong Ruichi New Materials Co., Ltd. is a scientific and innovative enterprise specializing in the research, development, design, production and installation of FRP, and cable tray and FRP cable tray are one of the products.

So many years have passed since the founding of New China, and China has always adhered to the two major policies of reform, opening up and scientific and technological innovation, and has also achieved remarkable results in recent years. Even in the 21st century, it will never give up.

The installation of bridge is mainly divided into several types: installation along the roof, horizontal and vertical installation along the wall, installation along the shaft, installation along the ground, installation of FRP bridge along the cable trench and pipeline support, etc. The supporting (hanging) frame used for installation can be finished products or self-made. The fixing methods of the support (hanger) mainly include welding on embedded iron pieces and fixing with expansion bolts. Where there are cables, there are bridges. Bridge is widely used in all walks of life, most of which are used in data centers, offices, Internet service providers, hospitals, school/university airports and factories, especially in data centers and IT computer rooms. The FRP bridge market reached 100 billion yuan in 2010, and will grow at a rate of about 20% every year after 2011. In 2010, the country issued the standard of cable tray, which stipulated the definition, model code, requirements, test methods, inspection rules, signs, transportation and storage of cable tray for electronic control distribution. This standard is applicable to cable trays for indoor and outdoor, high and low voltage transmission and distribution projects in industrial and civil buildings. The introduction of this standard further standardizes the FRP bridge industry. Good standards are also a new embodiment of standardized products.
