Procurement Guide for Semi-conductive Tetoron tape

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

Product Overview: Semi conductive Tetoron tape is made by impregnating and drying Tetoron tape with non-conductive adhesive. It has high mechanical strength and heat resistance (long-term temperature resistance of 150 ℃), and is designed specifically for high-voltage cross-linked polyethylene cables. It can evenly distribute electric fields and is suitable for conductor shielding and core wire binding.

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

• Conductivity: Surface resistivity of 10³~10⁸ Ω/sq (IEC 60243 standard).Tensile strength: ≥ 60N/cm, elongation at break ≤ 5%.

• Temperature resistance: No cracking after 180 ℃ × 24h thermal aging test.

Application scenarios

Suitable for conductor shielding layers of ultra-high voltage power cables (such as 500kV YJLW03), mining cables, and rail transit cables.

Procurement precautions

• Adhesive layer testing: Microscopic photographs are required to ensure uniform distribution of conductive particles (particle size ≤ 5 μ m).
• Supplier qualifications: Priority should be given to manufacturers who have participated in State Grid projects.
• Cost reference:Low priced products may use inferior glue. Avoid choosing low-priced products without testing reports.

Frequently asked questions

Q: How to avoid the adhesive layer from falling off during wrapping?

A: Select products with adhesive peel strength ≥ 3N/cm and control the wrapping tension between 8-12N.
