高性能玻璃钢电缆桥架的特性
在多年以前，电缆桥架的拉挤工艺主要由国外向我国供应，外国市场的主 导地位持续增强，我国进口以及学习工艺需要花费大量的时间精力，还未必能接触到核心技术，但是随着我国玻璃钢制品的广泛应用，大量应用于化工、冶金、有色金属等工业电器的电缆桥架拉挤生产工艺技术由外国垄断的局面终于被打破。
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.
近年来，随着我国化工、冶金等现代化工业的快速发展，也带动起了电缆保护玻璃钢电缆桥架制品需求量的迅速上升。然而，由于电器电缆系统设计的特殊性，对玻璃钢电缆桥架产品的耐腐蚀性、耐候性、耐老化性及绝缘阻燃性能的技术指标要求也越来越高。
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.
过去大多靠采用人工手糊的产品质量已远远达不到用户的要求。经过多年的玻璃钢电缆桥架技术攻关，终于开发出新工艺。采用新工艺生产的产品可完全能满足用户在不同地区、不同环境的要求下使用。
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.
新的玻璃钢电缆桥架工艺在技术创新上从四个方面显示出良好的特性，一是产品纵向强度、弯曲强度、剪切强度高；二是产品使用寿命可达50年以上，是钢制品的2～3倍；三是生产工艺自动化程度高；四是产品颜色鲜艳，品种繁多，满足了不同用户对产品着色的需求。
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.
