Copper strip wound into transformer coils, supplied in C1100 alloy at 0.2-3.0 mm thickness and 50-1350 mm width, with coil inner diameter of 300/400/500 mm or a customised size. Copper content is at least 99% and conductivity at least 99 %IACS, with tensile strength above 193 MPa, so the strip carries the design current without the resistive losses that force a winding redesign. The material is oxygen-free electrolytic copper with oxygen content under 0.02% and purity of 99.95% or higher, and the product range is built to comply with IEC, BIS and ASTM standards for buyers who ship transformers into regulated markets.
Width and thickness are cut to the winding drawing so your coil shop stops slitting stock strip and scrapping the offcut
Conductivity of at least 99 %IACS keeps winding resistance and load loss inside the values the transformer was designed to
Coil inner diameter of 300/400/500 mm or customised means the reels load straight onto your existing winding machine mandrel
Oxygen content below 0.02% reduces the risk of embrittlement at the brazed and welded joints in the coil
Compliance with IEC, BIS and ASTM standards gives the documentation your customer's type test file needs
Stock widths force in-house slitting, which adds a process step and generates copper scrap
Conductor below the specified conductivity raises load loss and pushes the transformer out of its guaranteed efficiency
Reels with the wrong inner diameter cannot be mounted on the winding machine without an adapter
Oxygen-bearing copper can embrittle during joint heating and fail after the coil is already assembled
Missing standard compliance stalls the type test and export documentation package

Strip fills the winding window more completely and reduces the number of parallel conductors to be handled
Copper carries more current per unit of cross section so the coil stays smaller for the same rating
Strip slit to the drawing removes an operation from your coil shop and avoids offcut scrap
C1100, made from oxygen-free electrolytic copper with oxygen content under 0.02% and purity of 99.95% or higher.
Thickness from 0.2 to 3.0 mm and width from 50 to 1350 mm, cut to the dimensions on your winding drawing.
At least 99 %IACS, with copper content of at least 99% and tensile strength above 193 MPa.
300, 400 or 500 mm, or a customised inner diameter if your winding machine mandrel needs a different size.
The product range is built to comply with IEC, BIS and ASTM standards. Tell us which one your customer references and the paperwork will follow it.
Order quantity depends on thickness width and coil size, and it is confirmed in writing with the quotation.
Width and thickness tolerance is set against the standard you nominate and is confirmed with the quotation rather than assumed.
Send the drawing, capacity or duty cycle you need and we will come back with the factory match, the build detail and the commercial terms.
