UL1631 30 V 60/80 °C Shielded PE/XLPE Wire (Class 2)

UL1631 is a XLPE-insulated hook-up wire manufactured by Xinya Electronic Co., Ltd. It is rated 30 V, 60 °C / 80 °C. The catalogue describes it as a shielded construction. It is supplied in 8 recorded constructions spanning 24–30 AWG, with an overall diameter of 1.9–2.8 mm, cut to the length you order.

UL1631 at a glance

• 24–30 AWG, across 8 listed constructions
• Both solid (single-strand) and stranded conductors are listed — 3 solid and 5 stranded
• Insulation wall 0.33–0.4 mm
• Overall diameter 1.9–2.8 mm
• Max. conductor resistance 94.2–381 Ω/km at 20 °C DC (roughly 28.7–116.1 Ω per 1,000 ft)
• All 8 listed rows carry a shield (26/0.10, 29/0.10, 32/0.10)

How UL1631 compares with its nearest alternatives

UL1631 and UL1691 share the 30 V rating and XLPE insulation. The distinction is in maximum conductor temperature (60 °C / 80 °C against 80 °C). Insulation wall is 0.33–0.4 mm against 0.25–0.31 mm. Size coverage is 24–30 AWG against 16–30 AWG.

UL1631 and UL3302 share the 30 V rating and XLPE insulation. The distinction is in maximum conductor temperature (60 °C / 80 °C against 105 °C). Overall diameter runs 1.9–2.8 mm for UL1631 against 0.6–1.5 mm for UL3302. UL3302 is the tighter of the two, so UL1631 is the option to take only when the larger diameter is acceptable. Insulation wall is 0.33–0.4 mm against 0.18–0.28 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 7/0.10 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 UL1631 table

“Insulation O.D. (mm)” is measured over the insulation, not over a jacket, tape or braid. “Jacket O.D. (mm)” is the finished cable diameter, which is the value to quote for gland, grommet and connector sizing. Conductor resistance is stated at 20 °C DC per kilometre — divide by 3.281 for ohms per 1,000 ft.

Questions buyers ask about UL1631

Which sizes of UL1631 are available?

24–30 AWG, across the 8 constructions in the table below. Sizes outside the table can be quoted on request.

Can UL1631 be supplied in both solid and stranded conductor?

Yes. The documented range covers 8 constructions, of which 3 are single-strand and 5 are stranded. Give the construction, not only the AWG, when you request a quotation.

What overall diameter does UL1631 run to?

The documented range is 1.9–2.8 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
