The right termination for every cable

From control wiring in a panel to 1000 mm² power cables on a transformer, the CASK Steel range covers copper and aluminium conductors with one part-number logic: the product, the cable section, the stud size and the finish. The lugs are part of our earthing and lightning protection programme.

Frequently asked questions

Which lug do I use for aluminium cable on a copper terminal?

A bimetal Cu-Al lug: the aluminium barrel takes the cable and the copper palm sits on the copper busbar or terminal, without galvanic corrosion.

Tinned or bright copper?

Tinned copper is standard for damp, coastal and aggressive sites, tinned busbars and long storage. Bright copper is available on order.
