H class 180°C To 220°C | Hermetic Dual Coat Magnet Wire Super Enamelled Copper & Aluminium Winding Wire | 6 SWG to 45 SWG | 1kg - 20kg Spool Packing for Motors & Transformers

• High-Temperature Resilience: Rated at Class H (180°C continuous working thermal index) to comfortably withstand temporary power surges, heavy operational loads, and extreme heat cycles without insulation breakdown.
• Premium Dual-Coated Insulation: Coated with high-grade Polyesterimide (EIW) or modified Polyurethane enamel, providing exceptional dielectric strength, moisture resistance, and chemical defense against transformer oils and impregnating varnishes.
• Two Conductor Options: Available in High-Conductivity Copper (for maximum efficiency and compact coil slots) and Lightweight Aluminium (for cost-effective, weight-sensitive industrial applications).
• Excellent Winding Flexibility: Superior mechanical adhesion and low-friction finish prevent cracking, peeling, or scraping, making it ideal for high-speed automated winding machines or manual hand-rewinding.
• Universal Application: The ultimate choice for rewriting or repairing heavy-duty industrial electric motors, automotive alternators, transformers, high-speed ceiling fans, and microwave coils.

Upgrade your electrical rewinding and coil assembly projects with our professional-grade Class H (180°C) Super Enamelled Winding Wire.

Engineered strictly for high-stress thermal and electrical environments, this magnet wire features state-of-the-art enamel insulation that remains stable up to a 180°C thermal index. Whether you are dealing with heavy continuous industrial currents or rapid heat surges, this wire ensures maximum service life, minimal degradation, and elite structural integrity.

To perfectly match your project specifications and budget constraints, we offer this Class H wire in two premium conductor variations:

• Super Enamelled Copper Wire: Features maximum electrical conductivity. Best for heavy-load applications where space is tightly constrained and you need maximum electromagnetic efficiency with minimal energy loss.
• Super Enamelled Aluminium Wire: Offers a highly cost-effective, lightweight alternative. Perfect for large-scale transformers, automotive components, and standard appliance motors where overall weight reduction and budget are top priorities.

The dual-coated enamel insulation isn't just highly heat-resistant—it is also remarkably tough. It resists scraping, abrasion, and tension stretching during the tight winding process. This low-friction formulation means it smoothly glides through high-speed automated winding machinery without jamming, kinking, or snapping.
