UL1032 1000 V 90 °C PVC Hook-Up Wire

UL1032 is a PVC-insulated hook-up wire manufactured by Xinya Electronic Co., Ltd. It is rated 1000 V, 90 °C. It is supplied in 25 recorded constructions spanning 10–30 AWG, with an overall diameter of 1.9–5.05 mm, cut to the length you order.

UL1032 at a glance

• 10–30 AWG, across 25 listed constructions
• Both solid (single-strand) and stranded conductors are listed — 8 solid and 17 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: 3000 VAC, 1 min

How UL1032 compares with its nearest alternatives

UL1032 and UL1015 share the PVC insulation. The distinction is in voltage rating (1000 V against 600 V) and maximum conductor temperature (90 °C against 105 °C). Overall diameter runs 1.9–5.05 mm for UL1032 against 1.9–12 mm for UL1015. UL1032 is the tighter of the two where harness space is limited. Size coverage is 10–30 AWG against 2–30 AWG.

UL1032 and UL1618 share the PVC insulation. The distinction is in voltage rating (1000 V against 300 V) and maximum conductor temperature (90 °C against 80 °C). Overall diameter runs 1.9–5.05 mm for UL1032 against 1.9–3.2 mm for UL1618. UL1618 is the tighter of the two, so UL1032 is the option to take only when the larger diameter is acceptable. Insulation wall is 0.79–0.83 mm against 0.39–0.47 mm.

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 UL1032 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 UL1032

Which sizes of UL1032 are available?

10–30 AWG, across the 25 constructions in the table below. Sizes outside the table can be quoted on request.

Can UL1032 be supplied in both solid and stranded conductor?

Yes. The documented range covers 25 constructions, of which 8 are single-strand and 17 are stranded. Give the construction, not only the AWG, when you request a quotation.

What overall diameter does UL1032 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.
