This diagram details each layer of the cable structure, with annotations for each layer. Below is an explanation of each layer:
1. Outer Sheath
- Color: Orange
- Material: Polyurethane (PU), Polyvinyl Chloride (PVC)
- Function: Provides final mechanical protection, abrasion resistance, corrosion resistance, and pressure resistance.
2. Armor Layer
- Color: Gray
- Material: Steel wire armor (galvanized steel wire or stainless steel wire)
- Function: Provides additional mechanical protection, especially in high-pressure and high-tension environments.
3. Inner Sheath
- Color: Green
- Material: Polyvinyl Chloride (PVC), Polyethylene (PE), Polyurethane (PU)
- Function: Provides initial mechanical protection and abrasion resistance.
4. Kevlar Strengthening Layer
- Color: Yellow
- Material: Kevlar rope or Kevlar fiber
- Function: Enhances the tensile strength, impact resistance, and abrasion resistance of the cable, preventing mechanical damage.
5. Shielding Layer
- Color: Blue
- Material: Braided shield (copper wire or tinned copper wire) or aluminum foil shield
- Function: Prevents electromagnetic interference, ensuring signal transmission stability and clarity.
6. Insulation Layer
- Color: Red
- Material: Polyethylene (PE), Polyurethane (PU), Cross-Linked Polyethylene (XLPE)
- Function: Provides electrical insulation, preventing short circuits and leakage.
7. Conductor
- Color: White
- Material: High purity oxygen-free copper, tinned copper, silver-plated copper
- Function: Transmits power and signals.
