Engineered for extreme thermal requirements and maximum slot fill-factors. These lightweight enameled rectangular conductors provide high-performance solutions for regional power networks.
As Asia's leading infrastructure, transport, and datacenter hub, Singapore is rapidly executing the Singapore Green Plan 2030. The city-state is implementing aggressive decarbonization initiatives that span across clean energy grids, electrified maritime transit, and EV fleet operations. These modern systems demand high-efficiency electric motors and distribution units, which directly relies on advanced enameled flat wires to minimize thermal dissipation and reduce component mass.
Compared to traditional round conductors, Enameled Flat Aluminum Wires present substantial spatial benefits. They offer an improved slot fill factor of up to 85%, which allows designers to pack more conductive material into motor slots. This significantly reduces eddy-current losses while promoting faster heat transfer. By substituting copper with premium aluminum grades, regional equipment builders in Jurong Industrial Estate, Tuas Port, and Changi Aviation Zone are achieving up to a 60% reduction in total weight and up to 45% lower structural costs.
Furthermore, Singapore’s extreme tropical humidity demands superior insulation durability. Our class 200 and class 220 enameled formulations are coated with high-performance Polyesterimide (PEI) and Polyamide-imide (PAI) resins. This chemical integration provides high dielectric stability, moisture resistance, and prevents premature insulation breakdown in continuous-load tropical environments.
Suzhou Daiming Electrical Materials Co., Ltd., is an internationally recognized, highly specialized manufacturer of high-quality enameled wires. From our massive, fully integrated production facility in Suzhou, China, we operate over 30 state-of-the-art winding wire lines. Our facilities span a sprawling 258,333.33 ft² and are equipped with real-time in-line conductor diameter monitoring and high-voltage spark testing technologies.
Our commitment to technical precision and operational reliability enables us to export hundreds of tons of high-conductivity enameled aluminum and copper-clad aluminum wires worldwide. By partnering with leading global logistics providers and shipping directly from Suzhou via Shanghai Port, we guarantee rapid delivery directly to the Port of Singapore, minimizing customs clearance times and keeping local projects strictly on schedule.
Our products strictly comply with international Standards IEC 60317, NEMA MW 1000, and GB/T 7673. Below is an engineering overview of our primary insulation classes.
