Wire Harness Tape Wrapping Methods​​

Different wrapping methods are applied based on the location and environmental requirements of wire harnesses:

1. ​​Engine Harness​​

   • ​​Environment​​: Harsh conditions (high temperature, oil exposure, vibration, corrosion).
   • ​​Tape Requirements​​: High-temperature resistance, wear resistance, oil resistance, flame retardancy, waterproofing, and corrosion resistance.
   • ​​Recommended Tapes​​: Junyan models ​​3301, 4020, 4020X​​
      

2. ​​Body Harness​​

   • ​​Environment​​: Frequent contact with other components, causing friction noise; wet-dry zone junctions require waterproofing.
   • ​​Tape Requirements​​: High noise reduction, wear resistance; butyl sealant for wet-dry zone sealing.
   • ​​Recommended Tapes​​: Junyan models ​​4000, 4400, 9060​​
      

3. ​​IP (Instrument Panel) Harness​​

   • ​​Environment​​: Concentrated controls/displays, prone to collision noise and electromagnetic interference.
   • ​​Tape Requirements​​: Electromagnetic shielding (aluminum foil tape), noise reduction, wear resistance; dry tape for local wrapping.
   • ​​Recommended Tapes​​: Junyan models ​​3401, 4400, 9050​​
      

      

4. ​​Door Harness​​

   • ​​Environment​​: Limited space, collision with rigid parts, noise risk.
   • ​​Tape Requirements​​: High wear resistance, noise reduction; color PVC tape for identification.
   • ​​Recommended Tapes​​: Junyan models ​​3100, 4210, 4400​​
      

      

5. ​​Roof Harness​​

   • ​​Environment​​: Confined space; thin harnesses may directly adhere to the vehicle body.
   • ​​Tape Requirements​​: Full wrapping with PVC tape or foam tape for lightweight fixation.
   • ​​Recommended Tapes​​: Junyan models ​​3100, 9010​​
      

      

6. ​​Headlight Harness​​

   • ​​Environment​​: High temperature near light sources, compact space.
   • ​​Tape Requirements​​: High-temperature resistance (flannel or PET cloth-based tapes).
   • ​​Recommended Tapes​​: Junyan models ​​4010, 4300​​
      

      

Key Terminology Clarification

• ​​湿干区连接处 (Wet-Dry Zone Junction)​​: Areas transitioning from exposed (e.g., engine bay) to enclosed (e.g., cabin) sections, requiring waterproof sealing
   
• ​​丁基防水泥 (Butyl Waterproof Sealant)​​: Used for sealing wire harness penetrations, providing long-term moisture isolation
   
• ​​铝箔胶带 (Aluminum Foil Tape)​​: Provides EMI shielding for sensitive electronic components in IP harnesses
