- Product Introduction

Our Non-Woven Covered Round Aluminum Wire is a lightweight insulation product for round wire winding applications. We wrap round aluminum conductors with polyester film and electrical-grade non-woven fabric. The composite insulation layer is tight with stable voltage withstand performance. Temperature rating is Class B (130°C). The round shape makes our product suitable for small and medium transformers, reactors, and solenoid valves. You get good insulation performance with the weight savings of aluminum. Production follows GB/T 7673 in-house standards. Resistivity at 20°C stays under 0.028010 Ω·mm²/m. Our quality system uses online eddy current flaw detection throughout production. This ensures conductors have no internal defects. Finished products get 100% visual inspection and batch sampling. Insulation thickness and breakdown voltage remain consistently within specifications.
Trusted by Coil Processing Factories
Our Non-Woven Covered Round Aluminum Wire sells to power equipment manufacturers and coil processing factories. Stable quality and fair prices have earned us loyal customers in multiple provinces. Round wire winds faster and works well with automatic winding machines. This is why many coil factories have added our product to their standard purchasing list. Customers choose us because we are reliable. Quality is consistent. Delivery is on time. And we respond when problems come up. That is our idea of good customer experience.
