What are the materials for making J1939 cables?

Conductor Material: High quality J1939 cables typically use high-purity oxygen free copper as the conductor material, which has good conductivity and thermal conductivity, effectively reducing resistance and transmission losses. Some cables may also be made of materials such as copper alloys or tin plated copper.

Insulation materials: Common insulation materials include polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), polyurethane (TPU), etc. XLPE and TPU materials have good insulation, temperature resistance, and mechanical properties, making them suitable for high-performance J1939 cables. Understanding the types and performance characteristics of insulation materials can help determine the quality and applicability of cables.

Shielding material: As mentioned earlier, the shielding layer is generally made of materials such as metal woven mesh or aluminum foil. The material and weaving density of metal woven mesh have a significant impact on the shielding effect. Shielding mesh with high material purity and high weaving density can provide better shielding performance. The aluminum foil shielding layer should have good flexibility and adhesion, and be not easily damaged or peeled off.
