CADWELD® Grounding Connections by Erico®
 

The design and installation of Electrical Grounding Systems is one of the most important aspects of any electrical distribution system. A key element of the electrical protection system is an effective, low-impedance ground system. It is crucial to ensure personnel safety, as well as, provide reliable protection for vital equipment and minimize service interruptions and costly downtime.

The CADWELD® exothermic welding process fuses conductors together to form a molecular bond with a current-carrying capacity equal to that of the conductor. Grounding systems incorporating this type of connection therefore operate as a continuous conductor with lower resistivity.

CADWELD® MULTI

CADWELD® MULTI is a complete welding system for improving grounding system performance, reliability and installation convenience.
CADWELD® MULTI simplifies the exothermic welding process. A single, universal mold offers the capacity to make over 30 separate connection types to perform connections to a ground rod.

How It Works
CADWELD® MULTI uses a combination of a generic mold block and a range of disposable gaskets (batting). The gaskets are compressed around the conductors to allow numerous different welded connections to be produced without the need to change the mold block for each connection type.

Applications
Multiple grounding connection capabilities are possible including the following:

  • Copper Cable/Solid to Copper Cable/Solid
  • Copper Cable/Solid Strip to Rebar
  • Copper Strip to Copper Strip
  • Copper Cable/Solid to Copper or Steel Strip/Lug
  • Galvanized Steel Strip to Galvanized Steel Strip
  • Conductor to Ground Rod
CADWELD® MULTI Features:
  • Now performs welds to ground rods
  • Versatile mold offers an unlimited variety of connections for grounding applications
  • Patented self-sealing system prevents weld metal leakage
  • Compact compression structure enables easy alignment of conductors
  • Easy to follow instruction guide
  • Lightweight kit for easy transportation
  • Easy-to-use system completes weld in seconds
Standard Compliance:
CADWELD® MULTI satisfies the requirements of:
  • BS 6651
  • BS 7430
  • NFC 15-100
  • IEEE® 837-1987
  • IEEE 80-2000
  • IEC℠ 1025-1 (ENV 61024-1)

CADWELD® PLUS System
   
 

The revolutionary CADWELD® PLUS System is a simplified method of performing exothermically welded electrical connections for both Cathodic Protection and grounding applications.

CADWELD® PLUS is the latest advancement in the continuing evolution of ERICO's exothermic products.

The CADWELD® PLUS integrated weld metal package has streamlined the installation process by eliminating ignition materials – resulting in a reduced set-up time.

The tamper-proof, integrated weld metal package consists of a steel cup containing CADWELD® patented weld metal alloys and ignition source. This weld metal package is designated for use in all standard CADWELD® molds, including CADWELD® MULTI. Once placed in the CADWELD® mold, the weld is electronically ignited using a simple battery-powered control unit with a six-foot lead.

CADWELD® PLUS System Features:

  • Offers all the benefits of conventional CADWELD® and more
  • Withstands repeated fault currents without failing during operation
  • Exceeds requirements of “IEEE® Std 837 – Std. for Qualifying Permanent Connections Used in Substation Grounding”
  • Joins copper to copper, copper to galvanized or plain steel, copper to copper clad steel, copper to bronze/brass/stainless, steel to steel, etc.
  • Consists of a tamper-proof, disposable, moisture resistant welding material cup. The welding material, disk and ignition source are incorporated into a self-contained package
  • Color coded welding material reduces the risk of misapplication and gives a simple visual verification of the correct welding material size
  • An Electronic Control Unit makes ignition simple with no starting material required
  • Six-foot control unit lead provides increased flexibility in hard to reach areas
