Types of Automotive Electrical Wires:
* Stranded: Consists of several thin conductors twisted together. More flexible than solid wire and better suited to areas where bending is required.
* Solid: Consists of a single solid conductor. Less flexible, but conducts more current per unit cross-sectional area.
* Twisted: Two or more insulated wires are twisted together. Provides increased flexibility and can be used for signal transmission.
* Flat: Consists of several flat conductors attached to a plastic or rubber base. Typically used for lighting and low voltage applications.
Characteristics of automotive electrical wires:
*Size: Measured in AWG (American Wire Gauge) unit. Lower AWG values indicate thicker wires that can handle more current.
*Voltage: Indicates the maximum voltage the wire can withstand.
* Temperature: Indicates the temperature range in which the wire can safely operate.
* Insulation: Material covering a conductor to protect it from short circuits and current leakage.
*Color: Used to identify wires and indicate their functions. Typically, black wires are used for grounding and colored wires are used for various circuits.
Typical wire colors in automotive wiring:
* Black: Earth
*Red: Constant battery power
* Blue: Ignition
*Yellow: Lighting fixtures
* Green: Sensors
*Brown: Accessories
*Pink: Fuel injector
*Orange: Immobilizer
Automotive electrical wire selection characteristics:
* Determine the required wire size based on the current it will carry.
* Select a wire with the appropriate voltage.
* Make sure the wire insulation can withstand the operating temperature.
* Use colored wires to make circuit identification easier.
*Use high quality wire with copper conductors and strong insulation.
