nVent CADDY CDY15PLUSF20 CADWELD Exothermic Welding System

nVent CADDY CDY15PLUSF20 CADWELD Exothermic Welding System

The nVent CADDY CADWELD Exothermic Welding System is built around the exothermic welding process, a trusted method electrical contractors use to create permanent, low-resistance connections for grounding and bonding work. Instead of relying on a mechanical clamp, lug, or bolted joint that can loosen or corrode over time, this CADWELD system fuses copper conductors together into a single, molecularly bonded connection. It is manufactured under the nVent CADDY brand, a name widely specified across commercial, industrial, and utility electrical projects for dependable grounding and bonding hardware. Because the resulting connection becomes part of the conductor itself rather than a separate fitting, it is intended to deliver long-term, maintenance-free performance in demanding field conditions.

Key Features

• Exothermic Welding Process: Uses a controlled exothermic reaction to fuse conductors into a permanent molecular connection rather than a mechanical joint.
• Corrosion-Resistant Connection: Produces a weld connection that resists loosening, corrosion, and degradation over the life of the installation.
• Permanent, Maintenance-Free Bond: Creates a one-time connection that does not require re-torquing or periodic maintenance like bolted or clamped hardware.
• nVent CADDY Brand Reliability: Backed by nVent CADDY, a brand widely specified by electrical contractors for grounding and bonding solutions.
• Consistent Electrical Continuity: Designed to maintain a stable, low-resistance electrical path at the connection point over the life of the system.

Technical Specifications

• Refer to manufacturer documentation for complete specifications.

Why nVent CADDY?

nVent CADDY has built a reputation among electrical contractors for dependable connection and support products, and the CADWELD exothermic welding system carries that same standard into permanent grounding and bonding connections. Rather than depending on a mechanical fitting that can work loose over time, a CADWELD connection becomes a fused, continuous part of the conductor itself, giving electricians and contractors a long-term, corrosion-resistant solution for critical grounding points. For contractors who need connections that hold up over the life of an installation, nVent CADDY CADWELD is a proven choice for professional electrical work.
