Proof of automotive high-voltage cable performance test results

On the road, the driving electric vehicle seems to be simple in the wiring structure, and the battery is connected to the wiring harness. But in fact, the application environment inside the electric vehicle is harsh, and the internal wiring of the vehicle is complex. Therefore, high voltage cables for vehicles have very important performance requirements. Therefore, the electric vehicle cable should be located in the small wiring space, high current and high voltage, high and low temperature environment is not good heat dissipation, especially in the north of the latitude, the low temperature environment affects the high voltage harness transmission power, the need to meet the high performance requirements of the cable. In addition, the vehicle driving environment is harsh with salt spray and electromagnetic fields, oil pollution and chemicals, low smoke halogen-free flame retardant and other environmental protection and safety requirements.

The following is a brief description of the test result process provided by the professional manufacturer of automotive cable: for reference.

Project: Low temperature winding test
Requirements: -40℃/4h winding no cracking/voltage resistance no breakdown
Objective: Put the wound high-voltage cable into the -40 degree incubator for four hours, and the surface of the product will not crack and crack after removal.

Project: short-term burn-in test
Objective: In order to simulate the change of insulating properties of running insulating materials under long-term operation by using laboratory equipment in the shortest time. Specifically, the experiment can be accelerated by artificially accelerating the aging of insulation materials. A better accelerated experiment method can have equivalence, typicality and repeatability, among which equivalence is often the most important, because it can truly reflect the aging process of insulation materials.

Of course, after a series of product tests, both the surface, cable bending and cable stretching of the product are still intact. Need to know more about EV cable product information, please visit: https://www.omgevcable.com
