TWP Automotive Wire – Thin-Wall PVC Insulated Wire for Low-Voltage Vehicle Applications
TWP automotive wire is a thin-wall primary wire insulated with polyvinyl chloride (PVC), designed for low-voltage 12V and 24V electrical systems in vehicles. Known for its flexibility and space-saving profile, TWP wire is widely used in automotive dashboards, interior control circuits, and low-current signal routing where lightweight, compact insulation is required.
With a temperature rating of -40°C to +80°C and voltage up to 60V, TWP wire offers sufficient thermal and mechanical performance for light-duty applications. It complies with SAE J1128 standards and is suitable for OEM harness manufacturing and aftermarket repairs.
