High voltage wiring harness is the main connection and transmission system for vehicle power supply and vehicle function realization. Due to the high voltage of new energy vehicles, there are many aspects to pay attention to in their design scheme, layout direction, etc.
The output voltage of the power battery is too high, which has already exceeded the safe voltage for human body. In the high-voltage wiring harness system, the DC high-voltage circuit must strictly follow the dual track system. Common high-voltage wiring harnesses include drive system high-voltage wires, power battery high-voltage wires, charging dock high-voltage wires, air conditioning compressor high-voltage wires, steering oil pump high-voltage wiring harnesses, and so on.
High voltage connectors are important carriers for connecting and transmitting high voltage and high current, and are important measures to ensure human safety. More mature and reliable suppliers include Amphenol, AVIC Optoelectronics, Tyco, and so on.
The high-voltage wiring harness of new energy vehicles is equivalent to the blood vessels of the car, running through various parts of the car, playing a role in signal transmission and power supply.
High voltage wiring harnesses have the characteristics of high voltage/high current, large wire diameter, and small bending radius. Connectors need to be interwoven with wiring harnesses and connectors to avoid connection failure.
High voltage wiring harness is the main artery of power transmission for new energy vehicles, and its material and technical requirements are more stringent than traditional wires. Dongguan Paige Rui provides 6-120 square meters of high-voltage wiring harness to meet the functional requirements of new energy vehicles, supporting shielded and unshielded structures.
Paige Rui High Voltage Wire Harness Testing Project:
In addition to the previous tensile and cross-sectional tests, the following tests have also been passed:
1. Short circuit test
2. Conducting resistance test
3. Insulation withstand voltage test
4. AC high voltage leakage current test
5. DC high voltage leakage current test
6. Air tightness test
Paige Rui has the production capacity of low-voltage and high-voltage wiring harnesses for new energy vehicles, and can produce low-voltage wiring harnesses made of PVC, TPE, PTFE, silicone, and irradiated XLPE materials, as well as high-voltage wiring harnesses made of PVC, silicone wire, and irradiated wire materials.
