UL 3266 XLPE 125°C 300V High Temperature Wire is a single-core appliance and equipment wire built with a copper conductor and cross-linked polyethylene (XLPE) insulation. This 300 V, 125°C construction is intended for internal wiring where a compact, flexible high-temperature wire is required. Documented conductor configurations span 10 AWG to 30 AWG; tinned or bare copper and insulation colour can be selected against the required build.
To quote the right configuration, provide the required AWG, conductor construction, insulation colour, installation temperature, length and application. TEBAOFLEX will confirm the suitable final construction before production.
What is UL 3266 XLPE wire?
UL 3266 wire is a single-conductor, XLPE-insulated hook-up wire identified by its 300 V and 125°C design parameters. XLPE is a cross-linked polyethylene insulation material used where internal appliance, electrical panel, switchgear, motor, transformer, relay or electronic-equipment wiring needs a higher temperature rating than conventional general-purpose wire.
Key design information
- Rated voltage: 300 V.
- Rated temperature: 125°C.
- Construction: single-core stranded copper conductor with XLPE insulation.
- Conductor options: bare or tinned copper configurations can be specified.
- Available size references: 10 AWG to 30 AWG.
- Installation guidance: the referenced minimum bend radius is 6 × finished outside diameter for the 16–22 AWG family; confirm the final requirement for the selected build.

Applications for 125°C XLPE hook-up wire
UL 3266 XLPE wire is specified for internal appliance wiring, electrical panels, switchgear, electronic assemblies and connections around motors, transformers, chokes and relays when the confirmed operating conditions are within the product design. Its single-core format makes it suitable for point-to-point wiring rather than replacing a multicore control cable.
How to select the right 300V XLPE wire
- Choose the AWG size from the required current-carrying and installation design.
- Specify tinned or bare stranded copper.
- State the insulation colour and whether a specific finished diameter is required.
- Provide the equipment type, routing, temperature and length for an engineering configuration check.
For higher-temperature fluoropolymer constructions, see the UL 1330 FEP high-temperature wire. Explore additional options in the high-temperature and specialty cable range.
Frequently asked questions
What is the temperature rating of UL 3266 wire?
The documented design temperature is 125°C. Confirm the complete equipment conditions and installation routing before final selection.
What sizes can be specified?
The documented family covers 10 AWG through 30 AWG. The selected size, stranding and finished diameter should be confirmed with the quotation request.
Can I order tinned copper XLPE wire?
Yes. The supplied data includes tinned-copper constructions, while bare copper is also identified as a configuration option. State the required conductor finish in the enquiry.
Is UL 3266 wire suitable for external power distribution?
No. This is a single-core internal equipment wire. Select a dedicated power or outdoor cable when the application requires multi-core, external, wet-location or heavy-duty mechanical protection.
