nVent ERICO Cadweld Cable to Ground Rod Welding Connections provide a permanent, low-resistance bond for durability and reliability. These connections maintain the same current capacity as the conductor. They withstand repeated fault currents without failure. Perfect for grounding systems, they form a molecular bond that will not loosen, break, or corrode.
Once completed, installers can verify the connection quality through visual inspection. With reliable connections that exceed IEEE® 837 2014 EMF test requirements, nVent ERICO Cadweld is the ultimate solution for grounding and bonding needs.
nVent ERICO Cadweld Cable to Ground Rod Welding Connections – Features
Forms a permanent, low-resistance connection
Provides a molecular bond for lasting durability
Rated with the same current capacity as the conductor
No external power source required for portable installation
Easy to train installers
Connections can be visually inspected for quality assurance
Cadweld Plus utilises the same moulds as the Cadweld Traditional range, but provides the welding material/ metals and starting powder in an enclosed metallic cup. Easier and quicker than Traditional, ignition takes place with a Remote Control Unit. This enables the operator to be even further away from the ignition.
Complies with all recognised Standards Bodies and is famous as the “Number 1” system for exothermic welding. nVent design and manufacture all components of the system in-house, ensuring compatibility across the whole range. When combined with nVent’s grounding and bonding products (ground rods, busbars, connectors, GEM, etc), you are installing the most trusted, complete system in the world – ready to meet any demand.
The CADWELD method fuses metals with a current-carrying capacity equal to the grounding conductor, enabling a better earthing path of potential short-circuit or lighting strikes. The range of exothermic connections includes:
Build your connection today: select your connection mold type, welding material and ignition system, and then round it out with trusted tools and accessories. If you have any questions or custom mold and connection needs along the way, our team is ready to help!
