How UL1745 compares with its nearest alternatives
UL1745 and UL10086 share the Fluoropolymer insulation. The distinction is in voltage rating (30 V against 600 V) and maximum conductor temperature (90 °C against 150 °C). Insulation wall is 0.125–0.29 mm against 0.26 mm. Size coverage is 30–36 AWG against 20–32 AWG.
UL1745 and UL1332 share the Fluoropolymer insulation. The distinction is in voltage rating (30 V against 300 V) and maximum conductor temperature (90 °C against 200 °C). Overall diameter runs 0.81–1.37 mm for UL1745 against 0.96–3.04 mm for UL1332. UL1745 is the tighter of the two where harness space is limited. Insulation wall is 0.125–0.29 mm against 0.33 mm.
Conductor construction and selection
Every construction listed for UL1745 is a stranded conductor, which suits harnesses and assemblies that are flexed or routed around a bend. The resistance column gives the maximum permitted value for the conductor at 20 °C DC.
How to read the UL1745 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.
Questions buyers ask about UL1745
Which sizes of UL1745 are available?
30–36 AWG, across the 3 constructions in the table below. Sizes outside the table can be quoted on request.
Is UL1745 a stranded conductor?
Every construction documented for this line is stranded. Confirm the strand count you need — the “n/mm” figure in the table — because resistance and flexibility both depend on it, and two rows at the same size can differ.
What overall diameter does UL1745 run to?
The documented range is 0.81–1.37 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
