PP Cable Filling Rope

T-TCSWZ Series Filler PP Filling Rope for Optical Cables

Filling rope is a non functional component added to make the optical cable structure round, mostly made of PP material.
It is used for filler of the flame-retardant, fire-resistant LSOH/LSZH flame-retardant, fire (oxygen)separated, LSLH flame-retardant cable.

Filling rope is a non functional component added to make the optical cable structure round, mostly made of PP material. PP Cable Filling Rope is used for filler of the flame-retardant, fire-resistant LSOH/LSZH flame-retardant, fire (oxygen)separated, LSLH flame-retardant cable.

Function of the Filler String In the Flame-retardant Cable Component

  • Filling rope ensures that the cable is of good roundness.
  • It can improve flame-retardant class of the cable when use filler with high oxygen index.
  • PP Cable Filling Rope can fix the cable core in a stable position.
  • It can increase cable’s tensile strength.

Meet Requirement to Filler Used for the Flame-retardant Cable

  • It mustn’t absorb the moisture.
  • Its operation temperature should be the same with that of the cable.
  • It should not pollute the environment and do harm to human body in process of wrapping.
  • It should have good tensile strength and certain elongation.
