UL1571 PVC Hook-Up Wire

UL1571 is a PVC-insulated hook-up wire manufactured by Xinya Electronic Co., Ltd. It is supplied in 15 recorded constructions spanning 22–32 AWG, with an overall diameter of 0.6–1.3 mm, cut to the length you order.

UL1571 at a glance

• 22–32 AWG, across 15 listed constructions
• Both solid (single-strand) and stranded conductors are listed — 5 solid and 10 stranded
• Insulation wall 0.18–0.27 mm
• Overall diameter 0.6–1.3 mm
• Max. conductor resistance 56.4–595 Ω/km at 20 °C DC (roughly 17.2–181.4 Ω per 1,000 ft)
• Routine withstand test on every listed row: 500 VAC, 1 min

How UL1571 compares with its nearest alternatives

UL1571 and UL10272 share the PVC insulation. Insulation wall is 0.18–0.27 mm against 0.2–0.22 mm. Size coverage is 22–32 AWG against 20–32 AWG.

UL1571 and UL11079 share the PVC insulation. Overall diameter runs 0.6–1.3 mm for UL1571 against 0.65–0.9 mm for UL11079. UL11079 is the tighter of the two, so UL1571 is the option to take only when the larger diameter is acceptable. Insulation wall is 0.18–0.27 mm against 0.2–0.21 mm. Size coverage is 22–32 AWG against 26–32 AWG.

Conductor construction and selection

Both conductor families are listed. Single-strand rows such as 1/0.254 at 30 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 UL1571 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 UL1571

Which sizes of UL1571 are available?

22–32 AWG, across the 15 constructions in the table below. Sizes outside the table can be quoted on request.

Can UL1571 be supplied in both solid and stranded conductor?

Yes. The documented range covers 15 constructions, of which 5 are single-strand and 10 are stranded. Give the construction, not only the AWG, when you request a quotation.

What overall diameter does UL1571 run to?

The documented range is 0.6–1.3 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
