H03VV-F 300/300 V PVC Flexible Multicore Cable

H03VV-F is a PVC-insulated flexible multicore cable manufactured by Xinya Electronic Co., Ltd. It is rated 300 V. The catalogue describes it as a multicore construction. It is supplied in 6 recorded constructions spanning 0.5–0.75 mm², with an overall diameter of 3.30 × 5.30 mm to 5.9 mm, cut to the length you order.

H03VV-F at a glance

• 0.5–0.75 mm², across 6 listed constructions
• Stranded conductor throughout the documented range
• Insulation wall 0.51–0.54 mm
• Overall diameter 3.30 × 5.30 mm to 5.9 mm
• Max. conductor resistance 26–39 Ω/km at 20 °C DC (roughly 7.9–11.9 Ω per 1,000 ft)

How H03VV-F compares with its nearest alternatives

H03VV-F and H05VV-F share the PVC insulation. The distinction is in voltage rating (300 V against 300 V / 500 V). Overall diameter is 3.30 × 5.30 mm to 5.9 mm against 3.95 × 6.30 mm to 14.6 mm for H05VV-F. Insulation wall is 0.51–0.54 mm against 0.6–0.91 mm.

H03VV-F and H07V-K share the PVC insulation. The distinction is in voltage rating (300 V against 450 V / 750 V). Overall diameter is 3.30 × 5.30 mm to 5.9 mm against 3.1–11.4 mm for H07V-K. Insulation wall is 0.51–0.54 mm against 0.75–1.87 mm.

Conductor, core count and shielding

Every construction listed for H03VV-F 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.

Core counts run from 2 to 3 in the documented range. Overall diameter grows with core count, so the figure to quote for gland, grommet and connector selection is the finished-cable diameter column rather than the single-core insulation diameter.

How to read the H03VV-F 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 H03VV-F

Which sizes of H03VV-F are available?

0.5–0.75 mm², across the 6 constructions in the table below. Sizes outside the table can be quoted on request.

Is H03VV-F 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 H03VV-F run to?

The documented range is 3.30 × 5.30 mm to 5.9 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
