The difference between automotive cables and wiring harnesses characteristics analysis

China [CN]

Cables and wiring harnesses are both used to connect electrical systems, but their structures, functions and application ranges are different. From the aspects of structure, function, application range, etc., they are as follows:

1. Structure: Cables are composed of one or more cores and insulating materials, usually with a certain shielding and sheath layer. They can be used alone or as connecting wires between components and electrical equipment. Wiring harnesses are composed of multiple cables or wires, with a relatively complex and complete structure, usually including connectors, connectors and protective shells.

2. Function: Cables are mainly used to transmit electrical energy and signals. In a single electrical system, they are responsible for the connection and communication between different electrical equipment and components, and play the role of transmitting power, voltage and signals. Wiring harnesses are a collection of multiple cables or wires, which can realize multiple functions such as power distribution, signal transmission, control and regulation, and are key components in vehicle electrical systems.

3. Application range: Cables are widely used in construction, communications, energy, manufacturing and other fields, and can be used in various low-voltage, medium- and high-voltage power transmission, lighting, control, communications and other occasions. Wiring harnesses are widely used in automobiles, aviation, railways and other fields. They are the core components of vehicle electrical systems and are used to connect various electrical equipment and components in the car, such as motors, lights, audio, air conditioners, etc.

In summary, although cables and wiring harnesses are both used to connect wires and cables in electrical systems, their structures, functions and application ranges are obviously different, and they need to be selected and applied according to actual needs. Please search: OMG EV battery cable
