Many years ago, the pultrusion process of cable tray was mainly supplied to China from abroad, and the dominant position of foreign market continued to strengthen. It took a lot of time and energy for China to import and learn the process, and it may not be able to contact with the core technology. However, with the wide application of FRP products in China, it is widely used in chemical industry, metallurgy and other fields The foreign monopoly of pultrusion technology for cable tray of nonferrous metals and other industrial electrical appliances was finally broken.
In recent years, with the rapid development of China's chemical industry, metallurgy and other modern industries, the demand for cable protection FRP cable tray products has also increased rapidly. However, due to the particularity of the design of electrical cable system, the requirements for the technical indexes of corrosion resistance, weather resistance, aging resistance and insulation flame retardant performance of FRP cable tray products are also higher and higher.
In the past, the quality of products that mostly rely on manual hand paste has far failed to meet the requirements of users. After years of FRP cable tray technology research, finally developed a new process. The products produced by the new technology can fully meet the requirements of users in different regions and different environments.
The new FRP cable tray technology shows good characteristics in four aspects: first, the product has high longitudinal strength, bending strength and shear strength; Second, the service life of the product can reach more than 50 years, which is 2-3 times of that of steel products; Third, the production process is highly automated; Fourth, the products are colorful and various, which meet the needs of different users.
