Type of Copper Cables

 

1.

The cable used in car reverse parking sensor system, it was connected between the host and CCD camera.

2.

Connected equipment including video and distance measuring sensor.

 

Vehicle Cables

1. Signal wire-(Annealed copper conductor+Crosslink FR polyolefin insulated+Filler+ Foil Shielding)
2. Power wire-(Annealed copper conductor+Crosslink FR polyolefin insulated)
3. Filler-Flame retardant yarn
4. Drain wire-Annealed copper wire
5. Shielding-Aluminum-polyester foil
6. Sheath- Crosslink flame retardant polyolefin.

 

Impedance:85Ω±10%.
Cable with flame, oil, abrasion and low temperature resistance complies with SAE J1128 general purpose specification.
