You're looking at a continuously transposed conductor built for big transformers and heavy electrcial equiment, and honestly, most buyers come to me wondering about the tolerances and insulation because that's what really matters in the long run. The single conductor thickness runs from 0.90 to 3.15mm, held to plus or minus just 0.01mm, with width between 2.50 and 13.00mm in the same tight tolerance — the width-to-thickness ratio sits between 2.0 and 9.0, which keeps eddy current losses down and space efficiency up. Insulation levels cover the whole alphabet from A through Y, C or whatever your design calls for, and we do enamel layers about 0.08-0.12mm thick with an epoxy resin coating of 0.03-0.05mm on top for mechanicla protection.
We've been supplying these to transformer manufacturers and instrument builders for years, and what it does is handle high currents in large windings without the hot spots you'd get from standerd round wire. Basically, the transposition evens out the magnetic field distribution — that's where the real performance gain is, not just in the copper or aluminum content. The maximum overall height goes up to 120mm and overall width maxes at 26mm (within plus or minus 0.05mm), so you can pack more conductive area into your coil without increasing the window dimensions.
Two groups of buyers come to us most often: the ones running large oil-immersed power transformers and those doing high-capacity dry-type units for industrial plants. 3 out of 5 clients are asking about paper-covered configurations right now, probably because of supply chain shifts we've seen since last year. It's better than using multiple parallel strands of round wire because you get tighter packing and fewer circulating currents in winding — that's a known headache with older designs.
Lead time is roughly 20-25 working days for the 5 to 80 strip configurations, depending on whether you need it in paper or film wrap over the enameled conductors (usually the paper option takes a bit longer). Also we comply with IEC, NEMA, GB, and JIS standard, and you'll get the COA with HPLC purity data if needed for your spec review. The MOQ is typically 500 kilograms or so for the bulk orders, but we can do smaller trial runs if you're testing a new transformer design — just confirm lead time on that because it changes with the epoxy curing schedule.
One thing nobody asks upfront but you'll wish you knew — the temperature class is rated at 120°C for continuous operation, which means it's not suited for high-temperature application like traction motors or generators running above that threshold unless you check the insulation spec carefully. Some buyers try to push it into dry-type transformers with higher thermal loads and end up needing the class R or H insulation instead. The price works out better than custom-wound alternatives when you're doing a production run of ten units or so, at least for the copper version.
For bulk orders, our MOQ is typically 500 kg per specification. But if you're testing a new design, we can work with smaller quantities — just reach out to sales.
We can supply ISO9001, CE, CCC, RoHS, and VDE certificates upon request. Just let us know which ones your project needs.
No, each CTC uses either all copper or all aluminum conductors — we don't mix materials within a single order. But you can order separate batches if you need both.
For a standard specification, lead time is about 25-30 working days. Custom insulation levels or sizes might add a week or two.
We spool it on heavy-duty wooden reels, wrapped with moisture-proof film and kraft paper. Store it indoors in a dry, well-ventilated area and it'll stay good for at least 12 months.
