Overview

EN IEC 60317-27-4:2020 / IEC 60317-27-4:2020 specifies requirements for paper tape covered rectangular aluminium winding wire. The standard covers wires whose conductor nominal dimensions range from width 2.00 mm to 16.0 mm and thickness 0.80 mm to 5.60 mm. The paper covering consists of two or more layers of paper tape and is primarily intended for winding coils for oil‑immersed transformers. Paper tape materials are restricted to those in IEC 60554-1 and IEC 60554-3-5. This part of the IEC 60317 family is intended to be used together with IEC 60317-0-9:2015 (general requirements for enamelled rectangular aluminium wire).

Key topics and technical requirements

The standard defines technical and test requirements including (but not limited to):

• Conductor dimensions and tolerances (width, thickness, corner rounding and maximum overall dimensions including covering)
• Increase in dimensions due to paper tape covering (tables and limits)
• Electrical resistance, elongation and mechanical properties (springiness, flexibility, adherence)
• Thermal and mechanical tests: heat shock, cut‑through, resistance to abrasion
• Chemical and environmental resistance: resistance to solvents, refrigerants, hydrolysis and transformer oil
• Dielectric and insulation tests: breakdown voltage, continuity of insulation, pin‑hole test, dielectric dissipation factor, temperature index
• Processing properties: solderability, heat or solvent bonding
• Loss of mass and other ageing / stability criteria
• Packaging requirements for safe storage and transport

These topics align with the IEC 60317 series structure and reference related test methods in the IEC 60851 series where applicable.

Applications and users

Practical applications and typical users include:

• Transformer manufacturers specifying paper‑tape covered rectangular aluminium wire for coils in oil‑immersed power and distribution transformers.
• Winding wire producers designing, manufacturing and certifying paper‑tape covered aluminium flat wire to meet buyer and regulatory requirements.
• Component and coil winding engineers who need to select wire that meets mechanical, thermal and dielectric performance for transformer windings.
• Test laboratories and quality assurance teams performing conformity and performance tests per the standard.
• Procurement and compliance professionals requiring clear product specifications and cross‑references for CE / CENELEC compliance (adopted as EN IEC 60317-27-4:2020).

Related standards

• IEC 60317-0-9:2015 - General requirements for enamelled rectangular aluminium wire (used in conjunction)
• IEC 60554-1 and IEC 60554-3-5 - Specifications for cellulosic papers for electrical purposes (paper tape materials)
• Refer also to test methods in the IEC 60851 series and packaging guidance in IEC 60264 series.

This standard is essential when specifying or testing paper tape covered rectangular aluminium wire for reliable, oil‑immersed transformer windings.
