Public transportation wiring harnesses refer to the collection of wires, connectors, and terminals that are used to connect various electrical components and systems within public transportation vehicles such as buses, trains, and trams. These wiring harnesses are designed to be durable and reliable, withstanding the constant vibration and movement of the vehicle while providing a safe and efficient means of transmitting power and data. They are typically composed of high-quality materials and undergo rigorous testing to ensure they meet industry standards for safety and performance. Common components found in public transportation wiring harnesses include power cables, control cables, signal cables, and sensors, all of which work together to ensure the smooth and reliable operation of the vehicle.
