Construction
Conductors: Typically made of stranded copper to provide flexibility and excellent electrical conductivity.
Insulation: High-grade materials like XLPE (cross-linked polyethylene) or EPR (ethylene propylene rubber) to withstand high temperatures and mechanical stress.
Shielding: Metallic shielding to protect against electromagnetic interference (EMI) and ensure signal integrity.
Outer Sheath: Durable and flexible outer sheath made of materials like TPU (thermoplastic polyurethane), rubber, or LSZH (low smoke zero halogen) to resist abrasion, chemicals, and environmental factors.
Additional Protection: Depending on the application, additional protective layers such as flame-retardant coatings, armoring, or water-blocking elements may be included.
