High Voltage Harness Guide

High-voltage wiring harness refers to the low-voltage system whose voltage is significantly higher than that of traditional fuel vehicles. It is mainly used for high-power power transmission in new energy vehicles and industrial equipment.

High voltage: refers to the ability to accommodate large currents above 400A, usually between ‌300V DC‌ and ‌1500V DC‌. In some scenarios (such as new energy commercial vehicles), it can reach ‌750V DC‌ or even ‌1500V DC‌.

Safety protection of high-voltage wiring harness: with IP67 protection level, orange appearance as high-voltage warning sign.

Environmental resistance of high-voltage wiring harness: Temperature range -40℃~150℃, some special designs can reach 180℃.

High-voltage wiring harnesses for new energy vehicles: divided into power battery cables, motor controller cables, fast/slow charging wiring harnesses, and high-voltage accessory wiring harnesses

Application areas of high-voltage wiring harnesses

New energy vehicles: realize high-voltage power distribution and energy management to meet the needs of fast charging, motor drive, etc.;

Energy storage system: carry 350A single-core current, support efficient energy transmission and signal stability;

Industrial equipment: such as excavators require anti-vibration design, and use flexible wiring harnesses to adapt to dynamic connections.

With the advancement of technology, high-voltage wiring harnesses have been continuously developing around safety, efficiency improvement and environmental adaptability, and will serve more widely in the fields of new energy and industrial intelligence in the future.
