Request certificate or datasheet →UL3271 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 26 recorded constructions spanning 10–30 AWG, with an overall diameter of 1.9–5.05 mm, cut to the length you order.
UL3271 at a glance
- 10–30 AWG, across 26 listed constructions
- Both solid (single-strand) and stranded conductors are listed — 8 solid and 18 stranded
- Insulation wall 0.79–0.83 mm
- Overall diameter 1.9–5.05 mm
- Max. conductor resistance 3.54–381 Ω/km at 20 °C DC (roughly 1.1–116.1 Ω per 1,000 ft)
- Routine withstand test on every listed row: 2000 VAC, 1 min
How UL3271 compares with its nearest alternatives
UL3271 and UL3272 share the 600 V / 750 V rating and 125 °C temperature rating. Size coverage is 10–30 AWG against 10–26 AWG.
UL3271 and UL3289 share the 600 V / 750 V rating and XLPE insulation. The distinction is in maximum conductor temperature (125 °C against 150 °C). Size coverage is 10–30 AWG against 10–28 AWG.
Conductor construction and selection
Both conductor families are listed. Single-strand rows such as 1/0.32 at 28 AWG suit fixed routing and insulation-displacement termination, where the conductor is not flexed after installation. Stranded rows such as 7/0.10 at 30 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 UL3271 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 UL3271
Which sizes of UL3271 are available?
10–30 AWG, across the 26 constructions in the table below. Sizes outside the table can be quoted on request.
Can UL3271 be supplied in both solid and stranded conductor?
Yes. The documented range covers 26 constructions, of which 8 are single-strand and 18 are stranded. Give the construction, not only the AWG, when you request a quotation.
What overall diameter does UL3271 run to?
The documented range is 1.9–5.05 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
