Earthing Electrodes, Washers and Rods for PV Earthing
Earthing Electrodes covers the parts needed for earthing and equipotential bonding. It includes stainless steel contact washers and plates for PV module frames, a sectional earth rod, an SDS MAX driving tool and a yellow-green earthing cable. It is intended for installers of photovoltaic and lightning protection systems.
What you will find in this category
- PV earthing washers and plates: A2 stainless steel (1.4301, grade 304), 40×40 mm, Ω-type 40×42×6 mm, and round Ø35 mm and Ø44 mm versions.
- Sectional earth rod: hot-dip galvanised steel, Ø16 mm, 1500 mm segment length, Morse taper lock, 2.4 kg.
- Driving tool: SDS MAX shank, hot-dip galvanised steel, 18x220 mm, for use with rotary hammers.
- Earthing cable: LgY 16 mm², yellow-green, PVC insulation, 450/750 V, class 5 flexible copper stranded conductor.
How to choose
- Application: washers and plates bond PV module frames to the mounting structure. The rod suits vertical earthing in lightning protection systems.
- Material: the PV contact parts are A2 stainless steel (1.4301, grade 304). The rod and driving tool are hot-dip galvanised steel.
- Size and hole: match the washer or plate to your fixing. Mounting or central holes range from 8 mm to Ø9 mm, depending on the model.
- Tool compatibility: the driving tool has an SDS MAX shank, so check that your rotary hammer accepts it.
- Conductor: the LgY cable has a 16 mm² cross-section and works from -40°C to +70°C.
Typical applications
The washers and plates are fitted under a screw. Their teeth or prongs pierce the insulating anodised layer on PV module frames and reach the aluminium beneath. This gives a continuous electrical connection to mounting rails and structure. The sectional rod is used for vertical earthing of buildings and industrial facilities. The cable is used in distribution boards and electrical systems.
Frequently asked questions
Why do PV earthing washers have teeth or prongs?
The anodised layer on module frames is an insulator. The sharp teeth or prongs pierce it as the screw is tightened. They reach the aluminium beneath and create the electrical connection.
What drives the earth rods into the ground?
The 18x220 mm driving tool has an SDS MAX shank. It is designed for rotary hammers and for installing earth rods in various soil conditions.
What is the operating temperature of the LgY 16 mm² cable?
The cable has PVC insulation and a class 5 flexible copper conductor. Its operating temperature range is -40°C to +70°C.
