Three-phase high-voltage harness for the drive motor

UEALINK Three-Phase High-Voltage Wiring Harness for Drive Motors

Product Overview

The UEALINK three-phase high-voltage wiring harness for drive motors is a dedicated cable assembly designed specifically for the electric drive systems of new-energy vehicles. It is primarily used to connect the PDU to the drive motor and falls under the category of shielded complete wiring harnesses for vehicle‑level motor controllers. The product employs fully covered, double‑layer shielded EV cables, which effectively isolate high-frequency electromagnetic radiation from the motor and provide strong resistance to electromagnetic interference. Its outer layer features corrugated tubing protection, enabling it to withstand the high‑temperature and oily conditions inside the engine compartment. All products undergo comprehensive automotive‑grade inspections and factory‑level dielectric strength and shielding tests, ensuring that the entire vehicle can pass EMC testing on the first attempt, helping customers reduce rework costs. This makes it a reliable choice for passenger car manufacturers, commercial vehicle makers, and electric drive system suppliers.

Core Design and Performance Features

This three-phase high-voltage wiring harness for drive motors is tailored to meet the actual operating conditions of electric drive systems. First, its fully covered, double-layer shielded EV cables represent the core design feature for addressing high-frequency electromagnetic radiation from the motor. These cables effectively block electromagnetic interference, preventing issues such as motor‑induced interference with the central control radar—a common problem with conventional, inadequately shielded wiring harnesses—thus ensuring stable operation of the vehicle’s electronic systems. Second, the corrugated tubing protective structure on the outer layer provides excellent physical protection, resisting high temperatures and oil contamination within the engine compartment, thereby extending the harness’s service life and adapting to the complex working environment of new-energy vehicles. In addition, the product is custom‑designed in length and equipped with bent connectors to perfectly match the installation requirements of different vehicle models, ensuring easy installation, high fitment accuracy, and seamless assembly without additional adjustments.
