Automotive Cable

Code Designation

1. Type of wire (German abbreviations)
  - FL = automotive wire
  - FLZ = automotive ignition wire

2. Conductor Materials (excluding electrolytic copper)
  - M = materials other than E-Cu or electrical resistance alloys
  - W = resistance wires

3. Characteristics of insulation materials
  - (no abbreviation) = Normal thickness
  - R = reduced insulation thickness
  - U = ultra thin insulation
  - S = increased insulation

4. Insulation and Sheath Materials

  Germany Standard
  - Y = soft-PVC (polyvinyl chloride)
  - YW = soft-PVC, heat-resistant, hot-pressure resistant
  - 4Y = PA (polyamide)
  - 6Y = FEP (tetrafluoroethylene hexafluoropropylene)
  - 7Y = ETFE (ethylene tetrafluoroethylene)
  - 11Y = TPE-U (thermoplastic polyurethane elastomer)
  - 13Y = TPE-E (thermoplastic polyester elastomer)
  - 2X = XLPE (polyethylene cross-linked)
  - 4G = EVA (ethylene/vinyl acetate)
  - 2G = SiR (Silicone rubber)

  Japanese Standard
  - A = automotive Low Tension Cable
  - V = polyvinyl Chloride Insulation
  - S = thin Wall Insulation
  - SS = extreme Thin Wall Insulation
  - XX = cross linked Insulation
  - T = twisted
  - E = polyethylene

EB = Electric Bond 
HEB = Heavy Duty Electric Bond 
HD = Heavy Duty 
C = Compacted 

American Standard 
- TWP = Thin wall, thermoplastic insulation low-tension cable for accumulator. 
- GPT = Thermoplastic insulation low-tension cable. 
- TXL = Thin-wall low-tension cables for automobiles. 
- GXL = Cross-linked polyolefin insulation low-tension cables for automobiles. 
- SXL = Cross-linked polyolefin insulation special purpose low-tension cables for automobiles. 
- HDT = Heavy duty, thermoplastic insulation low-tension cable for automobiles. 
- SGT = Starter or ground, general-purpose thermoplastic insulated. 

5. Shielding 
- B = Screen (film, foil) shield 
- C = Copper wire braiding 

6. Special Designs 
- F = Flat cable 
- Z = Multi-core separable cable 

7. Number of Cores and Cross Section 
- Indication of number of cores and cross-section (mm²) 

Examples: 

1. Single-core cables 
   - FLY1X0.5 
     - FL = Automotive cable 
     - Y = PVC insulation 
     - 1X0.5 = Nominal cross-section 0.5mm² 

2. Multi-core cables 
   - FLRYCY9X0.08 
     - FL = Automotive cable 
     - R = Reduced insulation thickness 
     - Y = PVC insulation 
     - C = Braiding of copper wires 
     - Y = PVC sheath 
     - 9X0.08 = 9 core, nominal cross-section 0.08mm²
