UL 10371 PFA 250°C 1000V High Temperature Wire is a single-core fluoropolymer insulated hook-up wire for protected internal wiring where both elevated temperature and a 1000 V rating are required. The documented construction combines PFA insulation with nickel-plated, silver-plated or bare copper conductor options in sizes from 10 AWG to 30 AWG.
What is UL 10371 PFA wire?
UL 10371 wire is a 250°C, 1000 V high-temperature equipment wire with PFA insulation. It is intended for protected internal appliance, electronic equipment and control wiring after the conductor size, plating, routing and final operating conditions have been confirmed. Search terms such as 1000V PFA wire, 250°C hook-up wire, high-voltage appliance wire and single-core fluoropolymer wire describe the same general purchasing need.
Key product features
- High operating temperature: documented temperature rating of 250°C.
- 1000 V rating: suitable for equipment designs that require more voltage capacity than common 300 V or 600 V hook-up wire.
- PFA insulation: a fluoropolymer insulation selected for demanding thermal and electrical environments.
- Conductor options: nickel-plated, silver-plated or bare copper can be specified according to the required termination and service conditions.
- Broad size range: available from 10 AWG to 30 AWG for power, control and internal connection requirements.
- Custom production: conductor configuration, insulation colour, printing, length and packaging can be reviewed against the project specification.

Typical applications
This 1000 V PFA insulated wire is designed for protected internal connections where heat, voltage and compact routing are important selection factors. Typical projects may include:
- High-temperature appliance internal wiring
- Electronic and electrical equipment connections
- Control cabinets and protected control circuits
- Heating equipment and thermal processing assemblies
- Laboratory, instrumentation and specialised OEM equipment
- Internal leads located near elevated-temperature components
Application suitability depends on the complete installation, including ambient temperature, conductor current, terminal system, mechanical protection and exposure conditions.
How to specify the correct 1000V PFA wire
- Confirm conductor size: select the AWG size from the electrical load, allowable voltage drop and terminal capacity.
- Select conductor plating: specify nickel-plated, silver-plated or bare copper based on temperature, termination process and project requirements.
- Check finished diameter: verify compatibility with connectors, seals, sleeves and equipment routing space.
- Define installation conditions: state whether the wire is fixed, occasionally moved, exposed to chemicals or installed near direct heat sources.
- Provide custom requirements: include insulation colour, printing, reel length, packaging and required test documentation.
Usage limits and engineering review
The listed temperature and voltage are product ratings, not approval of a complete machine or installation. Do not assume suitability for direct burial, continuous flexing, outdoor exposure, immersion, unprotected abrasion or a specific flame, oil or chemical test unless those conditions have been reviewed and confirmed. TEBAOFLEX can evaluate the requested construction against the intended equipment and operating environment.

Frequently asked questions
What is the main difference between UL 10371 wire and common 600V hook-up wire?
UL 10371 is documented for 1000 V and 250°C service. The higher voltage rating makes it relevant when a 600 V construction does not meet the equipment specification, subject to final engineering confirmation.
What conductor sizes are available?
The documented range is 10 AWG to 30 AWG. Representative dimensions are listed above; confirm the exact construction required for your terminal and routing system.
Which conductor materials can be supplied?
Nickel-plated, silver-plated or bare copper conductor options are documented. Selection should consider operating temperature, termination method and the complete application.
Is this wire suitable for continuous movement or outdoor installation?
The stated use is protected internal equipment wiring. Continuous flexing, outdoor exposure, direct burial and immersion require separate evaluation and should not be assumed from the temperature and voltage ratings alone.
What information is needed for a quotation?
Please provide the AWG size, conductor option, insulation colour, required length, packaging, operating temperature, voltage and equipment application. Drawings or terminal details are helpful when finished diameter is critical.
