CADWELD® High Voltage Cable Conductor Connections
 ERICO has provided the CADWELD® range of exothermic welding solutions to numerous cable manufacturers and installers around the world over many decades. Features
- Permanent molecular bond that does not loosen or deteriorate, providing a continual optimal electrical path
- Connections on large cross-section aluminum cables are more cost-effective and result in better electrical joints than other methods
- CADWELD range uses a specially developed aluminum alloy that makes it perfect for high voltage use
- Tested and certified as meeting the requirements of IEC1238 by such companies as Electricity de France
- Also available for copper-copper connections
Applications
- For both aluminum HV cables and large cross-section copper cables
- Can be used for underground high-voltage cables not under tensile load
More InformationThe CADWELD process is a method of making welded electrical connections in which no outside source of heat or power is required. For aluminum cable connections, powdered metals (tin oxide and aluminum) are dumped into a lid crucible section of a graphite mold and ignited by using a flint ignitor. The exothermic reaction that takes place is the reduction of tin oxide by aluminum. This reaction produces a superheated mixture of aluminum and tin that flows onto the conductors and causes them to be melted and then fused into a solid homogenous mass. After re-insulating the cable, the resulting connection will have a current-carrying capacity equal to or greater than the conductors being joined and the connection will not loosen, corrode or increase in resistance.
