UL3302 30 V 105 °C XLPE Hook-Up Wire

UL3302 is a XLPE-insulated hook-up wire manufactured by Xinya Electronic Co., Ltd. It is rated 30 V, 105 °C. It is supplied in 18 recorded constructions spanning 22–32 AWG, with an overall diameter of 0.6–1.5 mm, cut to the length you order.

UL3302 at a glance

• 22–32 AWG, across 18 listed constructions
• Both solid (single-strand) and stranded conductors are listed — 6 solid and 12 stranded
• Insulation wall 0.18–0.28 mm
• Overall diameter 0.6–1.5 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 UL3302 compares with its nearest alternatives

UL3302 and UL10368 share the 105 °C temperature rating and XLPE insulation. The distinction is in voltage rating (30 V against 300 V). Overall diameter runs 0.6–1.5 mm for UL3302 against 0.75–4.2 mm for UL10368. UL3302 is the tighter of the two where harness space is limited. Insulation wall is 0.18–0.28 mm against 0.25–0.39 mm.

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 UL3302 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 UL3302

Which sizes of UL3302 are available?

22–32 AWG, across the 18 constructions in the table below. Sizes outside the table can be quoted on request.

Can UL3302 be supplied in both solid and stranded conductor?

Yes. The documented range covers 18 constructions, of which 6 are single-strand and 12 are stranded. Give the construction, not only the AWG, when you request a quotation.

What overall diameter does UL3302 run to?

The documented range is 0.6–1.5 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
