H07V-K 450 V / 750 V 70 °C PVC Harmonised Cable

H07V-K is a PVC-insulated single-core cable manufactured by Xinya Electronic Co., Ltd. It is rated 450 V / 750 V, 70 °C. It is supplied in 8 recorded constructions spanning 1.5–35 mm², with an overall diameter of 3.1–11.4 mm, cut to the length you order.

H07V-K at a glance

• 1.5–35 mm², across 8 listed constructions
• Stranded conductor throughout the documented range
• Insulation wall 0.75–1.87 mm
• Overall diameter 3.1–11.4 mm
• Max. conductor resistance 0.554–13.3 Ω/km at 20 °C DC (roughly 0.2–4.1 Ω per 1,000 ft)
• Routine withstand test on every listed row: 2500 VAC, 1 min

How H07V-K compares with its nearest alternatives

H07V-K and H05V-K share the PVC insulation. The distinction is in voltage rating (450 V / 750 V against 300 V / 500 V). Overall diameter runs 3.1–11.4 mm for H07V-K against 2.3–2.6 mm for H05V-K. H05V-K is the tighter of the two, so H07V-K is the option to take only when the larger diameter is acceptable. Insulation wall is 0.75–1.87 mm against 0.64–0.69 mm.

H07V-K and H05V2V2-F share the PVC insulation. The distinction is in voltage rating (450 V / 750 V against 300 V / 500 V) and maximum conductor temperature (70 °C against 90 °C). Overall diameter runs 3.1–11.4 mm for H07V-K against 6.7–7.2 mm for H05V2V2-F. H05V2V2-F is the tighter of the two, so H07V-K is the option to take only when the larger diameter is acceptable. Insulation wall is 0.75–1.87 mm against 0.66–0.67 mm.

Conductor construction and selection

Every construction listed for H07V-K 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 H07V-K 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 H07V-K

Which sizes of H07V-K are available?

1.5–35 mm², across the 8 constructions in the table below. Sizes outside the table can be quoted on request.

Is H07V-K 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 H07V-K run to?

The documented range is 3.1–11.4 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
