UL 3266 XLPE wire 125C 300V for appliance internal wiring

Product Overview

UL 3266 XLPE wire is a practical choice for appliance internal wiring where buyers want a stronger insulation system than standard low-duty hook-up wire. In many appliance assemblies, the internal lead wire has to work inside compact spaces, remain stable over long service periods, and match the actual temperature environment of the product. That is where UL3266 becomes useful.

With a 125°C temperature rating and 300V profile, this style is often selected for internal leads in appliances, electrical products, and OEM assemblies where the application does not require a heavier 600V construction, but still benefits from XLPE insulation and a more durable internal wiring profile.

Key Ratings

UL Style: UL 3266 (AWM, UL 758)
Temperature Rating: 125°C
Voltage Rating: 300V
Insulation: XLPE
Conductor: stranded copper, tinned copper optional
Application type: appliance and equipment internal wiring

Why Buyers Use UL3266 in Appliance Wiring

Appliance internal wiring often looks simple from the outside, but the internal environment can still be more demanding than ordinary low-duty wiring suggests. Buyers choose UL3266 when they want a more durable internal wire for fixed lead routing, especially in products where temperature resistance and insulation reliability matter more than simply choosing the cheapest material.

XLPE insulation gives this style a stronger overall profile for appliance use, especially in OEM production where wire consistency and repeatable supply are important.

Typical Applications

Appliance internal wiring
Internal leads in compact electrical products
OEM appliance assemblies
Fixed routing in consumer and industrial equipment
Internal wiring requiring 125°C / 300V XLPE insulation

Factory-Backed Production Support

For appliance internal wiring projects, stable conductor quality and consistent insulation structure are often more important than broad sales wording. Buyers usually care about whether the wire can be supplied with repeatable quality across multiple batches, especially when the same product is used in repeated OEM production.

Selection Notes

If the project needs a higher-voltage XLPE construction, UL3271 or UL3321 may be more suitable. If the application requires silicone flexibility or fluoroplastic insulation, other AWM styles may fit better depending on the operating condition. UL3266 is more appropriate when the buyer wants a 125°C / 300V XLPE wire for appliance internal wiring and compact OEM lead systems.
