PP filling rope, also known as PP filler rope, is a type of material commonly used in power cables. It is made from polypropylene fibers that have been twisted and braided together to form a rope-like structure. PP filler rope is used to fill the spaces between the conductor and insulation layers of a cable to maintain its shape and prevent deformation.
The main characteristics of PP filler rope include:
Good thermal stability: PP filler rope can withstand high temperatures and has good thermal stability.
Low water absorption: PP filler rope has low water absorption, which means it is less likely to degrade or become damaged when exposed to moisture.
Excellent chemical resistance: PP filler rope is resistant to many different chemicals, making it suitable for use in harsh environments.
Lightweight and easy to handle: PP filler rope is lightweight and easy to handle, which makes it convenient to use during the cable manufacturing process.
Cost-effective: PP filler rope is a cost-effective material compared to other cable filling materials.
Overall, PP filler rope is a reliable and cost-effective material that is widely used in power cable manufacturing.
