Class 155 Polyester-Imide Enameled Magnet Wire 1mm
Class 155 polyester-imide enameled magnet wire, 1mm diameter, is an insulated winding wire used in high-temperature motor windings. Its polyester-imide insulation provides thermal endurance up to 155°C, making it suitable for demanding electrical applications. This product falls under tariff item 8544.19.00 as 'other' insulated winding wire, not being of copper or specifically covered elsewhere.
Class 200 Nomex Paper Covered Copper Winding Wire
Class 200 Nomex paper covered copper winding wire is an insulated winding wire with a paper-based insulation system rated for 200°C, used in large power transformers. Although the conductor is copper, the Nomex paper insulation means it is not covered by the copper-specific subheading 8544.11. It is correctly classified under 8544.19.00 as 'other' insulated winding wire.
Enameled Copper Magnet Wire 0.5mm
Enameled copper magnet wire, 0.5mm diameter with polyurethane enamel insulation, is used in electric motors and transformers. Despite being copper-based, its polyurethane enamel coating is not the typical varnish or enamel specified for copper wire under 8544.11. This product is classified under 8544.19.00 as 'other' insulated winding wire.
Fiberglass Insulated Rectangular Magnet Wire
Fiberglass insulated rectangular magnet wire features a rectangular copper or aluminum conductor wrapped with fiberglass sleeving and varnish, designed for generator windings. The composite fiberglass construction distinguishes it from standard enameled copper wire. It is classified under 8544.19.00 as 'other' insulated winding wire.
Formvar Insulated Fine Magnet Wire for Medical Devices
Formvar insulated fine magnet wire is a precision winding wire with polyvinyl formal (Formvar) insulation, used in medical imaging coils and precision instruments. The pinhole-free insulation is critical for biomedical applications. This product is classified under 8544.19.00 as 'other' insulated winding wire due to its specialized insulation.
Kapton Tape Wrapped High-Voltage Winding Wire
Kapton tape wrapped high-voltage winding wire uses polyimide tape insulation for power electronics applications requiring high thermal and dielectric performance. The tape-wrapped construction differentiates it from enameled wire. It is classified under 8544.19.00 as 'other' insulated winding wire.
Polyurethane Insulated Aluminum Winding Wire AWG 24
Polyurethane insulated aluminum winding wire, AWG 24, is an aluminum conductor with a polyurethane coating for small transformer and inductor windings. The aluminum conductor and polyurethane insulation place it outside the copper-specific subheading. It is classified under 8544.19.00 as 'other' insulated winding wire.
Self-Bonding Polyamide-Imide Magnet Wire 0.2mm
Self-bonding polyamide-imide magnet wire, 0.2mm, is an ultra-fine wire with adhesive properties for audio coils and precision instruments. The self-bonding feature allows coils to hold shape without additional adhesives. It is classified under 8544.19.00 as 'other' insulated winding wire due to its specialized properties.
Solderable Polyester Magnet Wire AWG 18
Solderable polyester magnet wire, AWG 18, is a copper conductor with polyester insulation designed for direct soldering without stripping, used in relays and solenoids. The solderable property is a specialized modification. It is classified under 8544.19.00 as 'other' insulated winding wire.
Triple Insulated Litz Wire for High-Frequency Transformers
Triple insulated Litz wire for high-frequency transformers consists of stranded conductors with triple-layer insulation to reduce skin effect losses in switch-mode power supplies. The multi-layer insulation and Litz construction are specialized. It is classified under 8544.19.00 as 'other' insulated winding wire.
