Procurement Guide for Power Cable PE Filling Strip
(Disclaimer: Some of the information in this article is sourced from the internet. Please carefully identify and use it.)

Product Overview: Ordinary filling strips are made of polyolefin as the main material and are foamed into a fan-shaped structure. They are lightweight, corrosion-resistant, and easy to install, and are widely used for filling medium and low voltage power cables.
Key performance indicators (for reference only, not used as procurement standards)
- Foaming rate:≥ 60%, density ≤ 0.5g/cm3to reduce cable weight.
- Flame retardant rating:If flame retardant performance is required, it must comply with IEC 60332-1 single vertical combustion test.
- Voltage endurance:breakdown voltage ≥ 20kV/mm (GB/T 1408 standard).
Application scenarios
Suitable for YJV and VV series power cables, especially for cost sensitive projects such as urban power grid renovation.
Procurement precautions
- Cost control: The content and quality of polyolefins are directly related to product performance, so avoid choosing low-priced products without testing reports.
- Environmental requirements:Ensure that materials are recyclable and avoid containing harmful substances.
- Supply stability: Choose manufacturers with a monthly production capacity greater than 100 tons to avoid the risk of stockouts.
Frequently asked questions
Q: What are the effects of uneven foaming of the filling strip?
A: May cause poor roundness of the cable, and it is necessary to randomly check the cross-sectional porosity during acceptance (should be<5%).
