Filling Yarn and Filling Rope
Polypropylene filling yarn and rope that keep multicore cable round, stable and economical to produce.

Large spool of cable filling rope with visible fiber texture
01 / 03Material — Cable auxiliary material
Function
Filling yarn and rope occupy the interstices between insulated cores during laying-up so the assembled cable is round and dimensionally stable before sheathing. Good filler is light, non-hygroscopic and consistent in diameter, letting the sheathing line run at full speed without lumps or diameter variation.
Supply Options
Standard polypropylene yarn and rope in a range of deniers and diameters; flame-retardant and low-smoke halogen-free grades are available to match LSZH cable designs so the filler does not undermine the cable’s fire performance.

Supply matching
Match the auxiliary material to the cable structure and process
Material structure, dimensions, roll or spool format and machine conditions determine stable production and finished-cable function.

- 01
Read the cable structure
Identify the shielding, filling, binding, separator or tensile function in the finished cable.
- 02
Define the supply specification
Confirm material construction, width, thickness, denier or diameter and roll or spool format.
- 03
Check machine compatibility
Match tension, overlap, line speed and pay-off conditions to the existing equipment.
- 04
Approve a representative sample
Verify handling, dimensions and finished-cable performance before the production order.
