IEC 62930 PV Cable, TUV R 50484553

IEC62930 is a photovoltaic DC cable manufactured by Xinya Electronic Co., Ltd. It is rated AC 1.0/1.0 kV, DC 1.5 kV. The catalogue describes it as a photovoltaic DC construction. It is supplied in 5 recorded constructions spanning 1.5–10 mm², with an overall diameter of 4.7–7.4 mm, cut to the length you order.

Type designation: IEC 62930, and how it relates to H1Z2Z2-K and PV1-F

IEC 62930 is the international counterpart of EN 50618. The two documents describe substantially the same cable — single-core, halogen-free, cross-linked construction over a flexible tinned-copper conductor for permanent outdoor DC service — and where they overlap the physical cable is the same. What differs is the document a project is procured against.

Unlike EN 50618, IEC 62930 does not use the H1Z2Z2-K harmonised designation. Cables to this standard are commonly ordered with a type reference printed alongside the standard number on the sheath, and the reference that appears in your project documents is the one that has to appear on the delivered cable — a site engineer reads the sheath, not the quotation. Tell us the reference your documents name and we will confirm it against the order.

So the three names you will meet on a European or international PV tender map as follows: H1Z2Z2-K is the harmonised designation defined by EN 50618; PV1-F is the trade name that grew out of TÜV specification 2 PfG 1169, still widely recognised outside the EU; and IEC 62930 is the international reference this line is built to.

IEC62930 at a glance

• 1.5–10 mm², across 5 listed constructions
• Stranded conductor throughout the documented range
• Overall diameter 4.7–7.4 mm
• Max. conductor resistance 1.95–13.7 Ω/km at 20 °C DC (roughly 0.6–4.2 Ω per 1,000 ft)

How IEC62930 compares with its nearest alternatives

IEC62930 and 2 PfG 1169 sit in the same catalogue group but are rated differently. Overall diameter runs 4.7–7.4 mm for IEC62930 against 4.7–8.4 mm for 2 PfG 1169. IEC62930 is the tighter of the two where harness space is limited. Size coverage is 1.5–10 mm² against 1.5–16 mm².

Conductor construction and selection

Every construction listed for IEC62930 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 IEC62930 table

“Insulation O.D. (mm)” is measured over the insulation, not over a jacket, tape or braid. “Cable 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 IEC62930

Which sizes of IEC62930 are available?

1.5–10 mm², across the 5 constructions in the table below. Sizes outside the table can be quoted on request.

Is IEC62930 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 IEC62930 run to?

The documented range is 4.7–7.4 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
