UL3272 600 V / 750 V 125 °C XLPE Hook-Up Wire

UL3272 is a XLPE-insulated hook-up wire manufactured by Xinya Electronic Co., Ltd. It is rated 600 V / 750 V, 125 °C. It is supplied in 22 recorded constructions spanning 10–26 AWG, with an overall diameter of 2–5.05 mm, cut to the length you order.

UL3272 at a glance

• 10–26 AWG, across 22 listed constructions
• Both solid (single-strand) and stranded conductors are listed — 7 solid and 15 stranded
• Insulation wall 0.79–0.83 mm
• Overall diameter 2–5.05 mm
• Max. conductor resistance 3.54–150 Ω/km at 20 °C DC (roughly 1.1–45.7 Ω per 1,000 ft)
• Routine withstand test on every listed row: 2000 VAC, 1 min

How UL3272 compares with its nearest alternatives

UL3272 and UL3271 share the 600 V / 750 V rating and 125 °C temperature rating. Size coverage is 10–26 AWG against 10–30 AWG.

UL3272 and UL3918 share the 125 °C temperature rating and XLPE insulation. The distinction is in voltage rating (600 V / 750 V against 300 V). Overall diameter runs 2–5.05 mm for UL3272 against 2–3.6 mm for UL3918. UL3918 is the tighter of the two, so UL3272 is the option to take only when the larger diameter is acceptable. Insulation wall is 0.79–0.83 mm against 0.44–0.49 mm.

Conductor construction and selection

Both conductor families are listed. Single-strand rows such as 1/0.404 at 26 AWG suit fixed routing and insulation-displacement termination, where the conductor is not flexed after installation. Stranded rows such as 7/0.16 at 26 AWG flex repeatedly and are the usual choice for hand-soldered harnesses and anything that has to follow a moving path. Conductor resistance is the same at a given size, so the choice between them is mechanical rather than electrical.

How to read the UL3272 table

“Insulation O.D. (mm)” is measured over the insulation, not over a jacket, tape or braid. Conductor resistance is stated at 20 °C DC per kilometre — divide by 3.281 for ohms per 1,000 ft. The withstand column is a routine production test applied to finished lengths, not a continuous working voltage.

Questions buyers ask about UL3272

Which sizes of UL3272 are available?

10–26 AWG, across the 22 constructions in the table below. Sizes outside the table can be quoted on request.

Can UL3272 be supplied in both solid and stranded conductor?

Yes. The documented range covers 22 constructions, of which 7 are single-strand and 15 are stranded. Give the construction, not only the AWG, when you request a quotation.

What overall diameter does UL3272 run to?

The documented range is 2–5.05 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
