Product Highlights

Installation Environment

H07V-K earthing cable is a flexible single-core conductor used in residential photovoltaic systems for protective earth and grounding connections. The cable is suitable for fixed wiring inside distribution boxes, switch panels, and where a dedicated earth conductor is required for PV mounting structures and protective devices.

Performance & Durability

The cable’s PVC insulation provides resistance to environmental influences, mechanical stress, and abrasion, making it suitable for typical electrical housing installations associated with solar PV systems. Its flexibility allows easy routing through cable ducts and conduits. While primarily designed for indoor or protected installation, the insulation offers some resistance to moisture and weather when routed appropriately.

Compliance & Safety

H07V-K complies with EN50525 standards for PVC insulated flexible conductors. It is flame retardant and meets RoHS and REACH environmental compliance requirements. The cable’s green/yellow insulation ensures clear earth identification and conforms to safety colorcoding standards.

Application Areas

Designed to serve as the protective earth conductor within residential PV systems, H07VK cable ensures safe grounding continuity between PV module frames, mounting structures, and electrical distribution earth paths.

Compatible with earthing bars and ground terminals in PV combiner boxes

Suitable for connection to solar panel frame earth points

Used in conjunction with PV inverter earth grounding points

Can integrate into residential switchboard and distribution earth networks

Can you check an equivalent cable from another manufacturer?

Yes. Send the exact cable designation and, where possible, the existing datasheet or project specification. We compare conductor material, construction, voltage rating, standards and the requirements that affect the installation before confirming whether an equivalent can be offered.

What if the required size, core count or construction is not shown on the website?

Send the exact requirement. The website does not represent every possible production combination. We will check whether the construction can be supplied and whether the required standards or certification scope also cover that version before it is quoted.

Can LV and MV cables be supplied in the drum lengths shown in our cable schedule?

Requested drum lengths can be reviewed with the cable schedule. What is practical depends on cable dimensions and weight, total quantity, drum capacity and transport or site-handling limits, so the required lengths should be included with the enquiry.

Is there one MOQ for all HORNOUR cable products?

No single MOQ applies across the entire range. The practical quantity depends on the cable type, size, construction, packing and production conditions. Send the actual cable list and quantities and we can confirm the applicable requirement for those items.
