Copper Foil and Strip
Copper Foil
C1100 copper foil for transformer windings, 0.2 to 3.0 mm thick and 50 to 1350 mm wide, on inner diameters of 300, 400 or 500 mm or customised.
Product Overview
C1100 copper foil for transformer windings, 0.2 to 3.0 mm thick and 50 to 1350 mm wide, on inner diameters of 300, 400 or 500 mm or customised. Copper content is 99% or higher, conductivity 99% IACS or better and tensile strength above 193 MPa. The material is oxygen-free electrolytic copper with oxygen below 0.02% and purity of 99.95% or higher, and it complies with American, European, German and Japanese standards. Supply covers transformer manufacturing, assembly, maintenance and repair.
Key benefits
Why Buyers Choose This Specification
Four Regional Standards Covered
American, European, German and Japanese standards are all named. For a transformer builder exporting to several markets, that removes a material qualification step per market.
Foil Winding Instead of Wire
A single foil sheet per turn eliminates the transposition and eddy current problems that stacked wire conductors have in a winding.
Oxygen-Free for Sound Joints
Oxygen below 0.02% and purity above 99.95% is what keeps brazed and welded winding joints from embrittling.
Width to 1350 mm
Foil winding needs strip as tall as the coil. A 1350 mm maximum width covers large distribution transformer coils in one piece.
Application scenarios
Where It Is Used
- Foil winding for cast resin and dry-type transformers
- Low voltage foil windings in oil-immersed units
- Transformer assembly and busbar connection
- Maintenance and repair rewinding
- Coils requiring full-height single-piece foil
- Export transformer manufacture requiring multi-standard material
Who it is for
The Buyers This Product Suits
Dry-Type Transformer Manufacturers
Foil winding is the standard construction for cast resin low voltage coils.
Exporters to Multiple Markets
Compliance with American, European, German and Japanese standards covers the major destinations in one material specification.
Repair Shops
Support extends through assembly, maintenance and repairs, not only new build.
Problems it solves
What It Fixes
Eddy Currents in Stacked Wire Windings
A single foil conductor per turn removes the circulating current losses that stacked parallel wires generate.
Material Qualification per Export Market
Compliance with four regional standard sets is stated for this product.
Joint Failure in Windings
Oxygen-free electrolytic copper avoids the embrittlement that causes it.

Sourcing And Inspection
This product is supplied through TrueGlow Imaging, working with manufacturing partners whose facilities are visited and verified rather than taken on trust. In-process quality control and delivery supervision are available so goods are inspected before the container is sealed. Certifications quoted on this page are those stated on the product specification and belong to that product range rather than to our trading entity, so ask for the certificate covering your specific item.
Handling guide
Getting It Right First Time
Step 1
Match foil width to the coil height so the winding is made in one piece.
Step 2
Specify thickness from the current density in your design, within 0.2 to 3.0 mm.
Step 3
Confirm inner diameter against your foil winding machine.
Step 4
Request certification against the specific standard your market requires.
Step 5
Handle foil edges carefully, since a nick becomes a tear during winding.
Comparison
How It Compares In Our Range
Copper foil against copper strip and aluminium foil.
| Copper Foil C1100 | 0.2-3.0 mm by 50-1350 mm, 99% IACS, compliant with American, European, German and Japanese standards. |
|---|---|
| Copper Strip C1100 | Same alloy and dimensional range, stated against IEC, BIS and ASTM standards. |
| Aluminium Foil | 63% IACS at lower weight and cost, for designs where a larger conductor section is acceptable. |
