AF250-3 Hookup Wire Nickel Plated Copper Core PTFE Insulation 600V for Industrial Building Use
Product Description
AF250-3 extruded PTFE wire consist of a nickel plated copper wire conductor and medium-wall PTFE extruded insulation. Rated at 600V AC and designed for continuous operation at 250°C, this 250°C high temp wire delivers stable performance in extreme environments. The AF250-3 is a premium PTFE insulated wire suitable for continuous operation at conductor temperatures up to 250°C, with short-term exposure capability to 250°C. It is particularly well-suited for current overload conditions, industrial building, mechanically stressed systems, and space-constrained installations where weight sensitivity is a concern, making it an ideal industrial hookup wire and industrial heat resistant cable.

Key Advantages 
  1. Nickel-Plated Copper Conductor: Excellent conductivity; flux-free direct soldering, a key highlight of our PTFE insulated wire.
  2. PTFE Extruded Insulation: Uniform, dense insulation layer for stable electrical performance, standard for high-quality 250°C high temp wire.
  3. Medium Wall Construction:Balanced protection and flexibility for general-purpose applications, ideal for use as industrial hookup wire.
  4. Wide Temperature Range: Reliable from -60°C to +250°C continuous; short-term to 300°C, cementing its status as a durable industrial heat resistant cable.
Application
  • 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.

Why Choose Our AF250 Series PTFE Insulated Wire?
The AF250-3 250°C high temp wire is the preferred choice for applications requiring proven PTFE reliability with cost-effective extruded construction. As a professional PTFE insulated wire, its silver plated copper wire conductor ensures low resistance and direct solderability, while the medium wall insulation wire structure provides uniform dielectric protection at 600V AC across a -60°C to 250°C temperature range.This versatile product performs equally well as aerospace PTFE wire, industrial hookup wire, industrial heat resistant cable, and auto wire with PTFE insulation. With exceptional chemical, oil, and weather resistance plus self-extinguishing flame retardance, it delivers mission-ready performance for general-purpose aviation and industrial wiring.
