AF250-3H Hookup Wire 1000V PTFE Insulated Wire for High Temperature Heating Electronics
-
Nickel-Plated Conductor: The nickel plated copper provides better oxidation resistance at high temperatures, ensuring stable performance and longer service life in heat-intensive applications.
-
PTFE Insulation: Offers good flexibility, resistance to repeated bending, and helps absorb vibration in moving parts or high-shock environments.
-
Wide Temperature Range: Works reliably from -60°C to 250°C, with the ability to handle brief temperature spikes up to 300°C without insulation damage.
-
Strong Electrical Insulation: Maintains high dielectric strength and arc resistance, with insulation resistance of ≥1.5×10⁶ MΩ·m at 20°C, protecting signal quality and system safety.
-
Chemical & Flame Resistance: Resists oils, fuels, solvents, and most chemicals. PTFE is naturally non-flammable and self-extinguishing.
-
Aerospace & Defense: Internal wiring of avionics, radar systems, and communication equipment.
-
Industrial Heating: Wiring for furnaces, ovens, and heating elements.
-
Instrumentation: Connection wires for sensors and meters in harsh environments.
-
Transportation: Wiring in electric vehicles, locomotives, and marine vessels.
-
Medical Equipment: Devices requiring sterilization or exposure to high temperatures.
