Material Provenance
A cable is not just 'plastic and metal'. It is a highly engineered composite. The passport records it all.
The Conductor
Tracking copper purity, stranding configuration, and recycled content percentage. Critical for both performance modeling and end-of-life recovery value.
- → OFC (Oxygen-Free Copper) purity levels
- → Tinned vs Bare vs Silver-plated
- → Exact AWG/mm² metrics per run
The Dielectric & Jacket
From FEP to PUR, the polymer composition dictates environmental resistance. The passport stores the exact compound formulation IDs.
- → Halogen-free (LSZH) verification
- → UV and Oil resistance ratings (e.g., UL Oil Res I/II)
- → Plasticizer declarations
