UL3289 600 V / 750 V 150 °C XLPE Hook-Up Wire

UL3289 is a XLPE-insulated hook-up wire manufactured by Xinya Electronic Co., Ltd. It is rated 600 V / 750 V, 150 °C. It is supplied in 25 recorded constructions spanning 10–28 AWG, with an overall diameter of 1.9–5.05 mm, cut to the length you order.

UL3289 at a glance

• 10–28 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 3.54–239 Ω/km at 20 °C DC (roughly 1.1–72.8 Ω per 1,000 ft)
• Routine withstand test on every listed row: 2000 VAC, 1 min

How UL3289 compares with its nearest alternatives

UL3289 and UL3271 share the 600 V / 750 V rating and XLPE insulation. The distinction is in maximum conductor temperature (150 °C against 125 °C). Size coverage is 10–28 AWG against 10–30 AWG.

UL3289 and UL3485 share the 150 °C temperature rating and XLPE insulation. The distinction is in voltage rating (600 V / 750 V against 600 V). Overall diameter runs 1.9–5.05 mm for UL3289 against 3.2–4.6 mm for UL3485. UL3289 is the tighter of the two where harness space is limited. Insulation wall is 0.79–0.83 mm against 1.09–1.41 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 7/0.127 at 28 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 UL3289 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 UL3289

Which sizes of UL3289 are available?

10–28 AWG, across the 25 constructions in the table below. Sizes outside the table can be quoted on request.

Can UL3289 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 UL3289 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.
