The future is the burst period of new energy vehicles. Enterprises are also actively responding to national policies and investing more and more in new energy vehicles. As a heat shrinkable tube manufacturer, Quantai is also actively cooperating with various new energy enterprises to solve various insulation and protection problems. Quantai constantly provides insulation and sealing solutions for the new energy industry and has always been one of the stable suppliers of the new energy automobile industry.

The company has been cooperating with new energy automobile company in product research and development, providing samples of various heat shrinkable tube products, supporting various heat shrinkable tube products and providing technical support. Verify materials and proportions from sample a; B-sample process verification; C-sample verification production line; D-sample mass production. Participated in the whole process from sample a to the mass production and marketing today. In this process, we constantly adjusted and optimized the material and production process of the heat shrinkable pipe to meet the needs of the product market in an optimal state.

The fields involved include new energy vehicle motor system, power supply power system and charging gun. The most important role of heat shrinkable tube is to cover and seal the insulation of motor harness and charging gun conductor, and to fix the harness. According to the feedback from the market, the heat shrinkable tubes provided by Quantai company have been performing their duty of insulation protection, and the aging degree is within the design range.

1、 Use case of heat shrinkable tube for motor system

Heat shrinkable tube is used for insulation sealing of oil pump motor cable

Heat shrinkable tube is used for insulation and sealing protection of oil pump motor cable

Heat shrinkable tube is used for outer layer protection of drive motor harness of new energy vehicles

Heat shrinkable tube is used for outer layer protection of drive motor harness of new energy vehicles

2、 Successful case of heat shrinkable tube used in new energy power system

Heat shrinkable tube with glue is used for sealing and waterproof at the connection of drive wheel and cable

Heat shrinkable tube is used for sealing and insulation at the connection of power battery and cable terminal

Heat shrinkable tube is used for sealing and insulation at the connection of power battery and cable terminal

Heat shrinkable tubes are usually used at the connection of cables and automobile parts

Heat shrinkable tubes are usually used for sealing and insulation treatment at the connection of cables and automobile parts

3、 The heat shrinkable tube is used for fixing and sealing the charging gun harness

Heat shrinkable tubes are not only used outside the charging gun, but also in the charging head

Heat shrinkable tubes are not only used outside the charging gun, but also inside the charging head for insulation of wiring terminals

The materials of the heat shrinkable pipes used are different according to the positions of the automobile parts. Here are some examples:

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

2. Cables at high temperature places such as drive motors need to use high temperature resistant heat shrinkable tubes as protective sleeves;

3. Double wall heat shrinkable tubes shall be used for the harness that needs to be waterproof at the interface of cable and battery;

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

5. For identification of cable number, use identification heat shrinkable tube.

After practical application, the heat shrinkable tube plays an important role in the new energy automobile industry and is an important supporting part that can not be ignored.
