4 Core Automotive High Temp Thinwall Cable - 1.5mm 21A

The 4 Core Automotive High Temp Thinwall Cable: 1.5mm (C403TW) is an advanced cable solution engineered for demanding automotive and marine wiring environments. Developed to exceed the performance of traditional Standard PVC BS6862 cables, this cable offers enhanced thermal endurance, reduced weight, and space-saving thinwall insulation.

This modern cable type is widely adopted by OEM manufacturers thanks to its robust design and reliability. Its hard-grade, lead-free thermoplastic PVC insulation provides exceptional resistance to heat, abrasion, and automotive chemicals, including petrol, oils, and diluted acids. With its plain copper conductors manufactured to strict international standards (ISO 6722, EN 13602, LV112), this cable guarantees stable performance and longer lifespan in both 12V and 24V systems.

Ideal for use in vehicle wiring harnesses, the 4-core construction makes it suitable for various multi-circuit applications such as lighting systems, sensors, and power distribution, while also helping to reduce cable bundle bulk by up to 30%.
