UL10272 150 V 80 °C PVC Hook-Up Wire

UL10272 is a PVC-insulated hook-up wire manufactured by Xinya Electronic Co., Ltd. It is rated 150 V, 80 °C. It is supplied in 18 recorded constructions spanning 20–32 AWG, with an overall diameter of 0.65–1.4 mm, cut to the length you order.

UL10272 at a glance

• 20–32 AWG, across 18 listed constructions
• Both solid (single-strand) and stranded conductors are listed — 1 solid and 17 stranded
• Insulation wall 0.2–0.22 mm
• Overall diameter 0.65–1.4 mm
• Max. conductor resistance 36.7–595 Ω/km at 20 °C DC (roughly 11.2–181.4 Ω per 1,000 ft)
• Routine withstand test on every listed row: 1500 VAC, 1 min

How UL10272 compares with its nearest alternatives

UL10272 and UL11079 share the 150 V rating and 80 °C temperature rating. Overall diameter runs 0.65–1.4 mm for UL10272 against 0.65–0.9 mm for UL11079. UL11079 is the tighter of the two, so UL10272 is the option to take only when the larger diameter is acceptable. Size coverage is 20–32 AWG against 26–32 AWG.

UL10272 and UL1061 share the 80 °C temperature rating and PVC insulation. The distinction is in voltage rating (150 V against 300 V). Overall diameter runs 0.65–1.4 mm for UL10272 against 0.75–2.7 mm for UL1061. UL10272 is the tighter of the two where harness space is limited. Insulation wall is 0.2–0.22 mm against 0.25–0.41 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 7/0.08 at 32 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 UL10272 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 UL10272

Which sizes of UL10272 are available?

20–32 AWG, across the 18 constructions in the table below. Sizes outside the table can be quoted on request.

Can UL10272 be supplied in both solid and stranded conductor?

Yes. The documented range covers 18 constructions, of which 1 are single-strand and 17 are stranded. Give the construction, not only the AWG, when you request a quotation.

What overall diameter does UL10272 run to?

The documented range is 0.65–1.4 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
