Procurement Guide for Circular PE Filler Strip

(Disclaimer: Some of the information in this article is sourced from the internet. Please carefully identify and use it.)

Product overview: The round PE filler strip is made of high-density polyethylene (HDPE), which has the characteristics of corrosion resistance, aging resistance, high insulation (breakdown voltage ≥ 25kV/mm), and is suitable for filling cables with high requirements for mechanical strength.

Key performance indicators (for reference only, not used as procurement standards)

• Tensile strength: ≥ 18MPa, elongation at break>300%.
• Temperature resistance: working temperature -50 ℃~80 ℃, short-term temperature resistance can reach 100 ℃.
• Environmental certification: SGS report is required to confirm the absence of polycyclic aromatic hydrocarbons (PAHs).

Application scenarios

Mainly used for medium and high voltage power cables (such as YJV22), photovoltaic cables, and outdoor weather resistant cables, especially suitable for industrial environments with large temperature differences and strong corrosiveness.

Procurement precautions

• Material purity: HDPE content ≥ 90%, avoid doping LDPE to reduce performance.
• Customization service: Supports customizing diameters according to cable cross-sections (such as φ 1mm~15mm).
• Transportation requirements: Choose UV resistant packaging to avoid deformation caused by prolonged exposure to sunlight.

Frequently asked questions

Q: How to choose between circular and fan-shaped filling strips?

A: Circles are suitable for high mechanical stress scenarios, while sectors are more suitable for cost sensitive projects.
