1. Better Bending 2. Better Gripping Strength, compressible clamp 3. Better Safety, if one strand is broken, other strands can still withhold the tension. For ACCC, once cracked it will break easily. 4. Better Tensile Strength 5. Better Sagging 6. Better Flexibility in Size / long span crossing, we can increase the size easily by adding extra strand - eg. for long river crossing.
