High & Low Voltage Wiring Harness

High and Low Voltage Wiring Harnesses are used to manage the distribution of electrical power and signal transmission across a wide voltage range in complex systems — such as electric vehicles, industrial equipment, aerospace systems, and smart infrastructure.
They are typically segregated but work together in parallel, where:
High voltage harnesses carry power (typically ≥60V DC / ≥30V AC),
Low voltage harnesses carry control signals, communication, or low-power circuits.
