When it comes to vehicles, wiring plays a huge role in keeping everything running smoothly. From headlights to the starter motor, the right automotive wire ensures that each system gets the power it needs. But not all wires are the same—different parts of a car require different types of wires depending on their purpose, environment, and power demands. Primary Wires Primary wires are the most common type used in cars. They carry low-voltage power to things like lights, dashboard controls, and relays. Made from flexible, multi-stranded copper, they can handle vibrations without breaking. Their insulation varies depending on the job: PVC insulated primary wires – Affordable and resistant to oil, grease, and acids. Commonly used in the cabin. GPT: General-purpose with standard wall thickness. TWP: Thin, lightweight, and rated for higher heat. HDT: Heavy-duty with thicker insulation for added protection. Cross-linked insulated primary wires (XLPE) – Tougher and more heat-resistant, p...
