The earthing rods are components of earthing devices for LV / MV overhead lines. They are made of steel profiles, protected by hot dip galvanizing against corosion.
The standard earthing rod has a hexagonal profile (code P2312-0-00).
The “T” profile earthing rod (code P2163-0-00) is a component of MV earthing device with self-locking phase clamps.
