Klauke 12SG10 manguito de unión cobre-aluminio 240 mm², estañado, 72 mm de longitud

For a seamless copper-to-aluminium transition in low-voltage networks, the Klauke 12SG10 connecting sleeve delivers a nominal conductor cross-section of 240 mm² within a compact 72 mm length and 21 mm outer diameter. Its tin-plated copper-aluminium body actively prevents galvanic corrosion, ensuring a stable electrical interface over the long term.

Overview

This uninsulated tubular sleeve is engineered for compression connections between stranded copper and stranded aluminium conductors. The bi-metallic construction with tin plating provides excellent corrosion resistance and maintains low contact resistance. Suitable for indoor and outdoor use when properly sealed, it operates reliably across a temperature range from -40°C to +120°C.

What stands out

• Bi-metallic copper-aluminium design eliminates galvanic corrosion between dissimilar conductors.
• Tin plating enhances corrosion protection and ensures low contact resistance.
• Compact 72 mm length fits easily into junction boxes and enclosures.
• Compatible with standard hydraulic or mechanical crimping tools.
• Designed to meet requirements for Cu-Al connections in low-voltage networks.
