Applications
Where CUPAL solves the copper-aluminium transition problem
Switchgear & Distribution Panels
Where aluminium feeders meet copper busbar — stable joints for decades, with an auditable mill certificate.
Cable Lugs & Connectors
Aluminium cable onto a copper terminal — a CUPAL washer in the bolted joint, or a CUPAL plate between lug and bar.
Lightning Protection
Three metals meet in every earthing system. The Al/Cu interface is the weak spot — CUPAL strip and transition pieces remove it.
Renewable Energy
Copper–aluminium transitions for solar, wind, BESS and EV charging systems — free of galvanic corrosion, lasting 15+ years.
Electric Vehicles & Charging Infrastructure
On the vehicle side — HV junction box, cable terminations; on the infrastructure side — MCS 1500 A. One bimetal material for both.
Busbars
Short-circuit-rated Cu/Al transitions — cut precisely to your busbar geometry.
