PV grounding cable and lightning protection

Flexible tinned copper earthing conductor for module frames, tracker piles, inverter stations and the plant earthing grid.

Product overview

Construction and performance

PV frames, tracker piles and inverter enclosures all have to be bonded, and the bonding conductor sits outdoors for the life of the plant. Tinned copper resists the corrosion that bare copper shows at clamped connections, and a flexible Class 5 or 6 conductor is easier to route around a tracker structure than a rigid earth bar.

Construction

  • Tinned copper, Class 5 / 6
  • Green-yellow LSZH sheath, or bare conductor
  • Corrosion resistant at clamped joints
  • Optional copper lug pre-assembly
  • Suitable for direct burial with protection

Applications

  • Module frame and rail bonding
  • Tracker pile and structure earthing
  • Inverter and transformer station bonding
  • Lightning protection down conductors

Selection notes

What to confirm before ordering

Bare or sheathed conductor?
Bare tinned copper is common for exposed bonding where mechanical protection is provided. A green-yellow LSZH sheath is used where the conductor is accessible and identification matters.
What size is needed for a module frame?
Sizing follows the lightning protection design and local code. The earthing designer should state the conductor size; we supply to that specification.
Are lugs available?
Yes. Tinned copper lugs and heat-shrink can be fitted to cut lengths where the connection points are known.

Need a sample or datasheet?

Tell us the system voltage, conductor size, length and destination. We can prepare a construction drawing and sample for review.

Packing and delivery

From the reel to the site gate

Cable is packed so it can be pulled without a re-reel, and documented so the site team can match each drum to the test report.

Drum packing

Wooden or steel-wooden drums for constructions above 16 mm², with lagging and a PE wrap. Drum diameter is selected so the cable is not bent below its minimum bending radius.

Coil and box

Small sizes and short lengths are supplied as coils in cartons or on pallets, wrapped and labelled with the same drum numbers used in the packing list.

Length control

Continuous length is measured during rewinding, and the delivered length is stated on the drum plate and the packing list. Short-length tolerance is agreed in the order.

Reel marking

Each drum is marked with product description, size, voltage rating, standard, length, gross weight, drum number and the project or PO reference.

Container loading

Drum layout and quantity per 20′ or 40′ container are planned by diameter and weight; a loading plan is issued before shipment.

Export documentation

Commercial invoice, packing list, bill of lading and certificate of origin are issued for the shipment; FOB, CIF and DAP terms are quoted on request.

Shipping documents

What travels with the shipment

  • Packing list with drum number, size, length and gross weight
  • Routine test report for the delivered length
  • Declaration of conformity and certificate copies for the tender file
  • Loading plan and photos before the container is sealed
