SUNBOW has a glass fiber tube SB-SGS-40 series, which is very suitable for high-voltage insulation of drive motors of new energy vehicles. The test was conducted at the Mercedes-Benz headquarters. After 30 days of continuous operation of the fiberglass tube on the lead of the drive motor, the fiberglass tube did not crack. Among domestic brands, only SUNBOW did it and eliminated all competitors. Among the insulating sleeves for new energy vehicle applications, most manufacturers are currently competing in the project of driving motors, but SUNBOW has developed the SB-SGS-40 series first, and its advantage is that SUNBOW insists on using it. Alkali-free and sodium-free glass fiber yarn and a certain brand of silica gel imported from Germany. After the tube is formed by the special weaving process of SUNBOW, the glass fiber tube yarn is tight and moderate, and the surface is smooth, which lays the foundation for the subsequent coating process. The toughness of German silicone raw materials is more than twice that of domestic silicone. With the help of a proprietary formula, the coated glass fiber tube has a brighter color, and its wear resistance and tear resistance are more than twice higher than those of the same industry. The temperature resistance reaches 260 degrees, and the temperature resistance of domestic counterparts is 200 degrees. The SB-SGS-40 series are mostly used in new energy vehicles. Therefore, there are not many domestic manufacturers with its production capacity. Many customers who find SUNBOW value whether the manufacturer has large-volume production capacity. SUNBOW has two factories in Shenzhen and Dongguan, with an output of 8.4 million meters per month. This is in a far leading position among domestic counterparts. At the Berlin exhibition in Germany in May 2019, the technical director of Mercedes-Benz headquarters directly tested the wear resistance and tear resistance of the SUNBOW fiberglass tube on the spot and found that the SUNBOW fiberglass tube exceeded many domestic and foreign manufacturers. At this time, the customer has already seen the capabilities and strengths of SUNBOW, and used SUNBOW fiberglass tubes in a recent new energy vehicle drive motor project.
