An nVent Earth Bond is a prefabricated assembly with a copper receptor plate Cadweldbonded to a copper conductor. The conductor is welded to the structure on site, creating an accessible, protected earthing connection to the foundation or rebar. It enables foundation earthing to be completed easily by anyone proficient in welding.
NVENT COPPER BONDED EARTH RODS
Longer life through molecular bonding
Copper bonded earth rods provide reliable grounding and long-term corrosion resistance for electrical installations. ERICO rods combine a high-strength steel core with a molecularly bonded copper coating for durable performance in demanding environments.
Why Grounding Matters
Grounding systems help to:
Protect people from electrical faults
Provide a reference point for equipment
Prevent flashover on transmission systems
Protect transformers, capacitors and lightning arresters
Why Copper-Bonded Rods?
Underground electrodes face harsh corrosion conditions. Copperbonded rods provide the ideal combination of:
Corrosion resistance
High conductivity
Strength for deep driving
ERICO Copper-Bonded Technology
ERICO rods use a continuous electro-plating process that creates a permanent molecular bond between copper and steel. This ensures the coating:
Will not slip or tear during installation
Will not crack when bent
Delivers decades of reliable performance
Copper-bonded ERICO rod won’t crack when bent
99.9% PURE COPPER COATING
High conductivity, corrosion resistance.
MOLECULAR COPPER BOND
Permanent copper–steel bond.
