UL 1330 FEP WIRE - 200°C

Our UL 1330 Type FEP (Fluorinated Ethylene Propylene) collection represents the gold standard for high-performance internal wiring. Rated for continuous operation at 200°C and 600V, these lead wires are engineered for environments where standard PVC or XLPE would fail.

Unlike standard high-temp wire, FEP insulation provides a unique combination of virtually total chemical inertness and superior dielectric properties, making it the preferred choice for oil and gas sensors, medical instrumentation, and high-end industrial ovens. With a thin-wall construction that doesn't sacrifice toughness, UL 1330 is optimized for compact electronic assemblies and aerospace applications that demand both flame resistance (VW-1 rated) and low-friction routing through tight conduits.

UL 1330 FEP High-Temperature Wire (200°C)

UL 1330 is a high-performance lead wire engineered for extreme environments requiring a combination of high-temperature resistance, excellent dielectric strength, and compact dimensions. Featuring a stranded tinned copper conductor insulated with a specialized Fluorinated Ethylene Propylene (FEP) jacket, this wire is rated for continuous operation at 200°C and 600V. Because FEP is a non-aging fluoropolymer, it is virtually immune to moisture, UV radiation, and a vast array of industrial chemicals and solvents. Its thin-wall construction allows for significantly more conductors to be routed through a single conduit or wiring harness compared to bulkier silicone-glass alternatives, making it the professional choice for sophisticated industrial and aerospace electronics.

Installation Note: While UL 1330 is incredibly durable chemically, its thin-wall FEP insulation is stiffer than silicone rubber. This "memory" makes it excellent for maintaining a specific shape in a harness but requires careful handling to avoid kinking during the initial pull. Because FEP has a higher melting point than standard solder, it is highly resistant to "shrink-back" during termination, allowing for very precise, clean soldering in tight connectors. However, always use specialized fluoropolymer wire strippers; standard strippers may struggle to cut through the tough FEP jacket cleanly without nicking the fine tinned copper strands underneath.

Key Features
  • 200°C Thermal Rating: Maintains its physical and electrical properties in extreme heat and remains flexible in temperatures as low as -70°C.
  • Chemical & Fluid Inertness: Provides nearly universal resistance to acids, alkalis, oils, and fuels, ensuring long-term reliability in harsh processing environments.
  • Thin-Wall Design: The high dielectric strength of FEP allows for a thinner insulation profile, reducing the overall diameter of the wire for high-density applications.
  • Low Friction Coefficient: The naturally "slick" surface of the FEP jacket makes it exceptionally easy to pull through complex conduit runs or tight wire harnesses.
  • Excellent Solderability: Features tinned copper conductors that resist oxidation and provide easy, reliable solder connections.
  • Non-Flammable: FEP is inherently flame-resistant and will not support combustion, meeting strict safety requirements for enclosed industrial systems.
Common Applications
  • Internal Appliance Wiring: Used in commercial ovens, high-end coffee makers, and industrial drying equipment.
  • Chemical Processing Equipment: Providing power to sensors and valves in environments where corrosive vapors or fluids are present.
  • Medical & Laboratory Instruments: Ideal for sterilization equipment and analytical devices requiring a chemically resistant, compact wire.
  • Aerospace & Defense Electronics: Used in flight control systems and communications gear where weight and space are critical factors.
  • Oil & Gas Downhole Tools: Reliable performance in the high-pressure, high-temperature (HPHT) environments of subterranean exploration.
  • Automotive Sensors: High-temperature lead wire for engine-mounted sensors and exhaust system monitoring.
  • Lighting Systems: Used as a ballast lead wire in high-intensity discharge (HID) and commercial LED fixtures.
