Kombinirani zvijavi materiali za električno izolacijo - 3. del: Specifikacije za posamezne materiale

Ta del standarda IEC 60626 določa mere in zahtevane karakteristike za posamezne kombinirane zvijave materiale za električno izolacijo. Ta del je v obliki skupin razpredelnic. Listi so oštevilčeni v skladu s preglednico 1, ki podaja popoln seznam vseh razpredelnic, ki spadajo k temu standardu. Materiali, ki so skladni s to specifikacijo, ustrezajo določenim ravnem delovanja. Vendar mora uporabnik material za določeno uporabo izbrati glede na dejanske zahteve za zadostno učinkovitost pri tej uporabi, ne samo na podlagi te specifikacije.

Overview

This CENELEC adoption (amendment A1 to EN 60626-3:2008, approved 2012) defines material-level specifications for combined flexible insulating materials (laminates) used in electrical insulation systems. It complements the base EN/IEC series by giving detailed requirement sheets for specific constructions - for example the triplex laminate P-H/F‑PET/P-H (hybrid inorganic‑organic paper 60 µm on both sides of a PET film). The amendment sets thermal classification guidance, single‑layer references and additional mechanical and electrical property limits used for manufacturing and testing.

Key topics and technical requirements

• Material descriptions and constructions: e.g., triplex laminates consisting of insulating paper (P‑H) and polyethylene terephthalate film (F‑PET).
• Thermal classification: practical suitability noted for apparatus rated up to the 155 °C–180 °C temperature range for certain laminates.
• Referenced single‑layer standards: hybrid paper to IEC 60819‑1 / IEC 60819‑3‑2; PET film to IEC 60674‑1 / IEC 60674‑3‑2.
• Dimensional and mass requirements: nominal laminate thickness and grammage values with tolerances (commonly ±15%).
• Mechanical performance: specified tensile strength and elongation in both machine (MD) and cross‑machine (CMD) directions, for unfolded and folded states.
• Electrical performance: minimum electric breakdown voltages for unfolded and folded samples (examples in the amendment range from ~5 kV to 21 kV depending on construction and thickness).
• Test and acceptance criteria: numeric tables in the amendment replace or add sheets (e.g., Sheets 340, 350, 351, and new Sheet 352) that manufacturers and test labs use to verify compliance.

Applications and users

Who uses EN 60626-3:2008/A1:2012:

• Material manufacturers specifying laminate formulations and production tolerances.
• Designers and engineers of electrical apparatus (motors, transformers, coils, power electronics) selecting insulating materials for thermal and dielectric performance.
• Testing and certification laboratories performing mechanical and electrical qualification.
• Procurement and quality assurance teams verifying supplier compliance.

Practical applications:

• Sourcing and qualifying combined flexible insulating materials for high‑temperature windings and insulation systems.
• Establishing production quality control limits (thickness, grammage, tensile strength, breakdown voltage).
• Ensuring interoperability with other IEC/CENELEC product standards and national adoptions.

Related standards

• IEC/EN 60626-3 (base standard)
• IEC 60626-2 (test methods referenced)
• IEC 60819‑1, IEC 60819‑3‑2 (paper requirements)
• IEC 60674‑1, IEC 60674‑3‑2 (PET film requirements)

This amendment provides precise, testable specifications that help manufacturers and laboratories ensure the safety, reliability and interchangeability of combined flexible materials used in electrical insulation systems. Keywords: combined flexible materials, electrical insulation, EN 60626-3:2008/A1:2012, triplex laminate, P‑H/F‑PET/P‑H, dielectric breakdown, tensile strength, thermal classification.
