In recent years, new energy vehicles have exploded, and companies have actively responded to national policies and invested more and more in new energy vehicles. As a heat shrinkable tube manufacturer, it actively cooperates with various new energy companies to solve various insulation protection problems. Duwai Company continues to provide insulation and sealing solutions for the new energy industry and has always been one of the stable suppliers in the new energy automobile industry.

   Since 2015, we have cooperated with new energy automobile companies in product research and development, providing them with samples of various heat shrinkable tube products, matching various heat shrinkable tube products, and providing technical support. Verify the materials and proportions from sample A; verify the process from sample B; verify the production line from sample C; and mass produce sample D. From prototype A to mass production in 2017, we are involved in the entire process. During this process, the material and production process of the heat shrink tube are constantly adjusted and optimized to ensure that the product is in the optimal state when it is launched on the market.

   The areas covered include new energy vehicle motor systems and power systems as well as charging guns. The most important role of heat shrinkable tubes is to cover and seal the motor wire harness and the insulation of the charging gun conductors, as well as to fix the wire harness. After several years of market feedback, the heat shrink tubing provided by Fuxinyi Company has been fulfilling its insulation and protection duties, and the degree of aging is within the design range. Some logistics obsolete models have gone through a life cycle. When we tested again, the aging degree of the parts protected by the heat shrink tube was obviously lower than that of the unprotected parts, and the heat shrink tube did not crack or fall off due to wind and sun. Phenomenon.

1. Use case of heat shrink tube used in motor system

Heat shrink tubing is used for insulation and sealing protection of oil pump motor cables

Heat shrinkable tube is used for outer protection of new energy vehicle drive motor wiring harness

2. Successful cases of heat shrinkable tubes used in new energy power systems

Glued heat shrink tube is used to seal and waterproof the connection between the drive wheel and the cable.

Heat shrinkable tube is used for sealing insulation at the connection between power battery and cable terminals

Heat shrink tubing is usually used to seal and insulate the connection between cables and automotive parts.

3. Heat shrink tube is used to fix and seal the charging gun wire harness.

Heat shrink tube is used to fix, seal and waterproof the charging gun port harness

Heat shrink tubing is not only used outside the charging gun, but also widely used inside the charging head for insulation of terminals.

   Depending on where the auto parts are used, the material of the heat shrink tube used also varies. Here are a few rough examples:

1. Use oil-resistant heat shrinkable tubing in the oil pump motor system;

2. Cables in high-temperature locations such as drive motors need to use high-temperature-resistant heat shrinkable tubes as protective sleeves;

3. Use double-wall heat shrinkable tubes for wiring harnesses that need to be waterproof at the cable and battery interface;

4. The cable of the charging gun uses double-wall heat shrinkable tube;

5. To identify the cable number, use heat shrinkable tubes.

   After practical application, heat shrinkable tubes play an important role in the new energy automobile industry. Although heat shrinkable tubes are not prominent in it, they are an important supporting component that cannot be ignored.
