TWP

TWP automotive wire with thin-wall PVC insulation, SAE J1128 compliant and rated -40°C to +80°C/60V. Ideal for dashboards, control circuits, and light-duty signal wiring.


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.


Key Features 

  • Operating temperature range: -40°C to +80°C

  • Voltage rating: Up to 60V

  • Thin-wall PVC insulation for compact harness layouts

  • Stranded bare copper conductor for flexibility

  • Complies with SAE J1128 specifications

  • RoHS compliant


Application 

  • Internal dashboard and control panel wiring

  • Signal and low-current circuits in passenger cars

  • Harnesses for light-duty vehicles and trailers

  • Compact routing within automotive infotainment units

  • Interior lighting and switch modules

TWP wire offers cost-effective, compact, and flexible performance for low-voltage vehicle wiring needs, especially in space-constrained environments where weight and bend radius matter.
