New opportunities for high-voltage wiring harnesses

The new energy vehicle harness market has reached 100 billion. The development of traditional automotive wiring harness is more mature, closely bound with the vehicle factory, which is a labor-intensive industry, and the value of passenger car wiring harness bicycle is 2500-4500 yuan. High-voltage wiring harness is another fast-growing sub-industry of new energy vehicles. At present, the wiring harness system of new energy vehicles is worth 5,000 yuan, and the high voltage wiring harness is worth 2,500 yuan, and the market exceeds 10 billion yuan.

The traditional path of power and data is essential. Like the blood and nervous system of the human body, the car wiring harness runs through all parts of the car, connecting all electronic parts and transmitting power and data.

New energy vehicles high voltage harness safety and reliability requirements are higher. 600V high voltage architecture requirements Harness: high voltage and current resistance, high protection level, electromagnetic shielding, insulation, high temperature resistance, high durability.

Industry status and future trends:

1. Low voltage wiring harness parts are many and complex, 70% manual production leads to low gross profit and production efficiency. The number of our own brand wiring harness factory is large, the single scale is small, the concentration is low, and it is in the rising stage of development. The future development direction is to continuously improve the level of automation, improve efficiency and gross profit margin.

2. High-voltage wiring harnesses have many fewer parts and lower complexity, but their pricing is high and their gross profit margin is much higher than that of low-voltage wiring harnesses. Chinese enterprises rely on the rapid development of domestic new energy vehicles and seize the market. In the future, the large-scale effect will be concentrated in the wiring harness factory, which will improve the gross profit and quality of products.

In 2017, China's automotive connector market size is about 18 billion yuan, and it can reach 27 billion yuan in 2025, and the increment is mainly contributed by high-voltage connectors. Domestic manufacturers will apply high-voltage and high-current connectors in other industries to electric vehicles, quickly seize the market to take the lead, the next step needs to gradually develop a complete product series, enhance their competitiveness, and strengthen the binding relationship with the vehicle factory.

4. Due to the convenience of the car body wiring and the safety of high temperature resistance, high pressure silicone rubber cable is the future direction of development, at present, foreign manufacturers in China have no production line, automotive silicone lines are imported, long delivery time, expensive, domestic manufacturers are stepping up development to make up for the gap in technology and production capacity.
