UL3385 300 V 105 °C XLPE Hook-Up Wire

UL3385 is a XLPE-insulated hook-up wire manufactured by Xinya Electronic Co., Ltd. It is rated 300 V, 105 °C. It is supplied in 21 recorded constructions spanning 16–28 AWG, with an overall diameter of 1.1–2.4 mm, cut to the length you order.

UL3385 at a glance

• 16–28 AWG, across 21 listed constructions
• Both solid (single-strand) and stranded conductors are listed — 7 solid and 14 stranded
• Insulation wall 0.39–0.47 mm
• Overall diameter 1.1–2.4 mm
• Max. conductor resistance 14–239 Ω/km at 20 °C DC (roughly 4.3–72.8 Ω per 1,000 ft)
• Routine withstand test on every listed row: 2000 VAC, 1 min

How UL3385 compares with its nearest alternatives

UL3385 and UL3567 share the 300 V rating and 105 °C temperature rating. Overall diameter runs 1.1–2.4 mm for UL3385 against 1.05–2.7 mm for UL3567. UL3385 is the tighter of the two where harness space is limited. Size coverage is 16–28 AWG against 14–30 AWG.

UL3385 and UL10368 share the 300 V rating and 105 °C temperature rating. Overall diameter runs 1.1–2.4 mm for UL3385 against 0.75–4.2 mm for UL10368. UL3385 is the tighter of the two where harness space is limited. Insulation wall is 0.39–0.47 mm against 0.25–0.39 mm. Size coverage is 16–28 AWG against 10–30 AWG.

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 UL3385 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 UL3385

Which sizes of UL3385 are available?

16–28 AWG, across the 21 constructions in the table below. Sizes outside the table can be quoted on request.

Can UL3385 be supplied in both solid and stranded conductor?

Yes. The documented range covers 21 constructions, of which 7 are single-strand and 14 are stranded. Give the construction, not only the AWG, when you request a quotation.

What overall diameter does UL3385 run to?

The documented range is 1.1–2.4 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
