SUNBOW fiberglass tubes are used for the insulation protection of drive motors of new energy vehicles in Mercedes-Benz, and domestic car companies are also choosing SUNBOW fiberglass tubes. Why is this? Let me explain!

The application of glass fiber tubes to the drive motor system of new energy vehicles for insulation protection seems to be a very mature and common solution. Electric vehicle technology is innovating, and insulating sleeves are also a rising star-glass fiber tubes suitable for automated production, such as SUNBOW's fiberglass tube series SB-SGS-40.

Benz fiberglass tube is used for the insulation of the drive motor. Simply put, the fiberglass tube is used for flame retardant insulation when the motor is running. This design not only effectively controls the driving of the entire car when the motor is running, but also has good wear resistance and tear resistance in the application of glass fiber tubes. The glass fiber tube here has successfully replaced the traditional silicone tube application. The success of the silicone tube application has indeed solved the insulation protection problems of car companies one after another, but with the smart factories and robot automation production lines of major car companies The trend of glass fiber tube is even better.

Our SUNBOW fiberglass tube SB-SGS-40 (full name Silicone Rubber Fiberglass Tube) is now being selected by several major domestic high-quality traditional car companies and new Internet car manufacturers, and is undergoing trials at different stages. Moreover, in the customer's motor selection, they are all against the first-line brand products such as Dafengen and Varflex. Why do customers choose SUNBOW's glass fiber tube SB-SGS-40? In fact, we are not afraid to compete with foreign brand products, because our glass fiber tube series have the following advantages:

1. After the hard work of the research and development team, we will not look at false reports for the sake of data. The data in our specifications are written by laboratory tests.

2. Even though our laboratory has complete physical properties, flame retardant performance and other test reports, we are still conducting reliability life tests at third-party testing institutions.

3. Because our products speak with real strength, it is also to allow car enterprise customers to find truly high-quality casing products in the red sea of insulating casing industry today.

Mercedes-Benz's drive motor supplier found SUNBOW at the Berlin exhibition in Germany, and he held a sample in his hand and told us that many Chinese manufacturers’ bushings were not tear-resistant, which caused them to be damaged during the motor test. It takes time and manpower, but also a waste of money. They have very high requirements for glass fiber sleeving, not only have good insulation properties and flame retardant properties, but also have very high requirements for the tear resistance of glass fiber sleeving. Because the drive motor is in a rotating state for a long time, if the glass fiber casing is not tear resistant enough, the casing will easily burst, which will not achieve the insulation protection effect. We tested samples for customers on the spot, but the customers were still worried, and took some samples back to test, and the results were very satisfied. Now SUNBOW supplies glass fiber tubes to Mercedes-Benz new energy drive motors every month, and there has not been any complaint of quality accidents in the past few years.

The customer told me two days ago that it is not easy for us to find a good insulating sleeve supplier, SUNBOW, it is worth choosing!
