The function of cable filler:
Filling function: Cable filling mainly serves to fill the gaps inside the cable, filling between the cable insulators to make the internal structure of the cable more compact and uniform. The use of fillers can effectively reduce the internal gaps of cables, improve the tensile strength and pressure resistance of cables, and reduce the vibration and pressure of cables during operation.

 The benefits of PE foam cable filling strip：
1、Lightweight, lightweight, and cost-effective
2、Environmentally friendly, resistant to chemical corrosion
3、Good flexibility and high tensile strength
4、Good insulation and flame retardancy
5、Waterproof and moisture-proof, structurally stable
6、Physical foaming, carbon dioxide foaming, can be recycled and reused
