High-performance wire solutions engineered for global telecommunications and heavy-duty electromagnetic operations.
In the rapidly evolving telecommunications market, modern network infrastructure demands components that exhibit high-frequency stability, lightweight profiles, thermal resilience, and economic sustainability. The global push for 5G expansion and the early conceptualization of 6G systems have forced engineers to reconsider traditional copper-centric component architectures. Specifically, Class 180 Enameled Aluminum Round Wire has emerged as the definitive standard for next-generation telecommunication transmitters, RF filtering systems, and high-frequency transformer subsystems.
International telecommunication equipment manufacturers face continuous pressure to optimize weight and cost profiles while retaining high levels of transmission fidelity. Weight reduction has direct commercial implications, particularly for tower-mounted transceiver assemblies such as Massive MIMO (Multiple Input Multiple Output) antennas. Heavy copper windings create structural issues on mast sites, escalating logistics, and tower installation costs. Enameled aluminum wire, offering roughly one-third the weight of copper at comparable resistance metrics, effectively alleviates mechanical stress and enables larger-scale deployments.
Aluminum offers a dramatic weight reduction benefit (2.7 g/cm³ versus copper’s 8.9 g/cm³), directly lowering physical load on telecommunication transmission towers.
Rated at Class 180 (H), the insulation layer sustains operating conditions up to 180°C without dielectric degradation or mechanical embrittlement.
Uniform enameled coating prevents breakdown during high-frequency cycles, crucial for RF filters and high-frequency amplifiers.
Procurement officers are constantly dealing with volatile commodity copper prices, which can compromise budgeting and project continuity for major global network projects. Enameled aluminum wire provides a highly predictable cost structure. By establishing high-volume supply relationships with Chinese manufacturers and exporters, global buyers secure pricing stability, ensuring long-term infrastructural buildouts remain within budget allocations.
We offer an integrated catalog of enameled conductor lines engineered for high-performance industrial applications:

Delivering maximum electrical conductivity and superior ductility for micro-motors, relays, and coils.
Combines the conductivity of copper with the lightweight properties of aluminum for RF cable shields.
Optimized continuously transposed conductors (CTC) to minimize winding losses in major power networks.
The performance profile of Class 180 Enameled Aluminum Round Wire in high-frequency applications depends on the precise formulation of its polymeric insulation coating. By coating EC-grade (Electrical Conductor) aluminum with a combination of Polyesterimide (PEI) and an optional outer coating of Polyamide-imide (PAI), manufacturers create a wire that resists physical damage while offering high dielectric strength.
In high-frequency telecommunications equipment, electrical current concentrates at the surface of the conductor (the skin effect). Because signals travel along the surface layer, the quality of the interface between the conductor surface and the dielectric insulation layer is critical. Class 180 wire is manufactured with smooth, defect-free drawing processes to ensure low attenuation of RF signals. Below is a comparative overview of conductor characteristics under thermal stress:
| Conductor Metric | Class 180 Enameled Aluminum | Enameled Copper equivalent | Copper-Clad Aluminum (CCA) |
|---|---|---|---|
| Density (g/cm³) | 2.70 | 8.89 | 3.63 |
| Conductivity (% IACS) | 61 - 62% | 100 - 101% | 63 - 65% |
| Thermal Rating Class | Class 180 (H) / Class 200 | Class 155 to 220 | Class 130 to 180 |
| Tensile Strength (MPa) | 80 - 120 | 200 - 250 | 110 - 150 |
| Corrosion Resistance | High (due to protective oxide/enamel) | Medium | Medium-Low |
As network bandwidth demands push telecommunications systems to operate at higher millimeter-wave frequencies, thermal stress within compact base stations will increase. Class 180 insulation provides the heat-resistant performance required to handle thermal loads in high-temperature environments. Our ongoing R&D programs focus on developing thinner insulation walls (Grade 1 and Grade 2 options) with increased dielectric strength to support modern, space-saving telecom component designs.

Class 180 Enameled Aluminum Wire offers a lightweight alternative for high-frequency RF systems. Because high-frequency currents travel primarily on the outer surface of the conductor (the skin effect), the smooth surface profile and uniform insulation layer of our aluminum wire provide equivalent signal integrity to copper while reducing component weight by up to 60%.
The thermal rating of Class 180 (Class H) indicates that the wire's insulation system is designed to operate continuously at 180°C. This thermal limit is critical for high-power telecommunication transmitters, preventing short circuits and dielectric failure under high temperature loads.
We use laser-controlled monitoring systems on our 30 state-of-the-art production lines to measure enamel thickness in real time. We perform breakdown voltage, elasticity, and pinhole tests to ensure compliance with IEC, NEMA, and GB standards.
