Procurement Guide for Semi conductive Nylon Tape

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

Product Overview: Semi conductive nylon tape is made of nylon substrate impregnated with non-conductive adhesive, with a surface resistivity of 10³~10⁵Ω/sq, which can evenly distribute electric field and is suitable for high-voltage cable conductor shielding and insulation protection.

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

• Conductivity: The surface resistivity must comply with the IEC 60243 standard (10²~10⁶Ω/sq).
• Temperature resistance:Long term working temperature of 150 ℃, short-term temperature resistance of 180 ℃.
• Mechanical strength: Tensile strength ≥ 50N/cm, elongation<5%.

Application scenarios

Specially designed for conductor winding of high-voltage cross-linked polyethylene cables (such as YJV62), ultra-high voltage power cables (500kV and above), and mining cables.

Procurement precautions

• Uniformity of adhesive: Microscopic photos are required to confirm the distribution of conductive particles without clumping.
• Supplier experience: Priority should be given to manufacturers who have participated in State Grid projects.
• Cost control: Low priced products may use inferior glue. Avoid choosing low-priced products without testing reports.

Frequently asked questions

Q: How to avoid wrinkling when wrapping?

A: Select a strip with a thickness of 0.1 ± 0.02mm and control the winding tension at 10-15N.
