Types of wires used in automotive electrical
The automotive electrical system uses different types of wires, each designed for a specific purpose:
* Wire Insulated Wire: Insulated with a thin layer of plastic, provides good protection against short circuits and excessive heat. Typically used to connect sensors, switches and other low current components.
*Rubber Insulated Wire: Thicker rubber insulation provides better resistance to high temperatures and environmental conditions. Suitable for connecting components in the engine compartment and other harsh environments.
* Teflon Insulated Wire: Features heavy-duty Teflon insulation that can withstand extremely high temperatures. Often used to connect electronic engine control units and other important components.
* Silicone Insulated Wire: Silicone insulation is flexible and resistant to a wide range of temperatures. Suitable for connecting electronic components and also in environments with vibration and high currents.
* Coaxial cable: Consists of a center conductor surrounded by insulation and braiding. Used to transmit high frequency signals such as audio or ignition signals.
* Stranded Wire: Contains several thin wires twisted together. More flexible than solid wire, making it suitable for connecting components that move or vibrate frequently.
* Shielded Wire: Has an additional layer of conductive sheath around the insulation. Protects the wire from electromagnetic interference, ensuring more stable signal transmission.
Wire color coding
To make it easier to identify wires in an automotive electrical system, standard color coding is used:
* Black: Typically used for grounding.
*Red: Battery positive cable.
*Yellow: Battery or power after ignition.
* Blue: Typically used for lighting.
*Green: Typically used for signal wires.
*White: Typically used for lighting grounding.
*Purple: Typically used for accessory wires.
*Orange: Typically used for control wires.
It is important to follow standard color coding to ensure proper wiring and diagnosis of the vehicle’s electrical system.
