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.

近年來，隨著我國化工、冶金等現代化工業的快速發展，也帶動起了電纜保護玻璃鋼電纜橋架制品需求量的迅速上升。然而，由于電器電纜系統設計的特殊性，對玻璃鋼電纜橋架產品的耐腐蝕性、耐候性、耐老化性及絕緣阻燃性能的技術指標要求也越來越高。

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.

過去大多靠采用人工手糊的產品質量已遠遠達不到用戶的要求。經過多年的玻璃鋼電纜橋架技術攻關，終于開發出新工藝。采用新工藝生產的產品可完全能滿足用戶在不同地區、不同環境的要求下使用。

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.

新的玻璃鋼電纜橋架工藝在技術創新上從四個方面顯示出良好的特性，一是產品縱向強度、彎曲強度、剪切強度高；二是產品使用壽命可達50年以上，是鋼制品的2～3倍；三是生產工藝自動化程度高；四是產品顏色鮮艷，品種繁多，滿足了不同用戶對產品著色的需求。

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.
