The IWRC Structure of the Steel Wire Rope - Part 2

The advantages of IWRC wire ropes

Compared with fiber-core steel wire ropes, the IWRC structure has brought about significant performance improvements:

1. Higher strength: The metal core itself is made of steel wire and can withstand a significant portion of the tension. Therefore, under the same diameter, the breaking tension of IWRC steel wire rope is approximately 7% - 15% higher than that of FC steel wire rope.

2. Better resistance to compression and deformation: The metal core is very hard and can better resist external pressure (such as the compression from the lower layer rope on the upper layer when multiple layers are wound) and radial deformation caused by drums and pulleys.

3. Higher flexibility life (under specific conditions): Although the initial flexibility may be slightly worse, under heavy load, high pressure and high bending stress conditions, IWRC can better support the outer strands, reduce internal wear, and thereby extend fatigue life.

4. Better high-temperature adaptability: The fiber core will carbonize and fail at high temperatures, while IWRC can withstand higher temperatures (although extremely high temperatures will still affect the performance of the steel wire).

5. Smaller rope diameter elongation: The fiber core is compressed in the initial stage, causing the rope diameter to slightly shrink and the length to extend. IWRC does not have this problem.
