Klauke 11SG10 Bi-Metal Sleeve for Aluminium-Copper Conductors 185 mm², Tin-Plated, Crimp Connection, 65 mm Length

Joining aluminium and copper conductors directly often leads to galvanic corrosion, which degrades the connection over time and increases resistance. The Klauke 11SG10 bi-metal sleeve eliminates this risk by providing a secure, corrosion-resistant crimp joint between aluminium and copper conductors of 185 mm² cross-section. Its tin-plated copper side and aluminium side ensure a durable, low-resistance connection, ideal for low-voltage power distribution and busbar applications.

Who is it for

This sleeve is intended for electricians, panel builders, and maintenance professionals who need to join aluminium and copper conductors safely in industrial, commercial, or utility installations. It is suitable for cable connections, transformer terminations, and distribution boxes where mixed-metal connections are required.

Main features

• Bi-metal construction: aluminium barrel on one side, tin-plated copper barrel on the other, preventing galvanic corrosion.
• Designed for 185 mm² conductors on both sides, ensuring a proper fit and optimal crimping.
• Crimped connection for a gas-tight, mechanically strong joint that maintains low contact resistance.
• Conforms to DIN 46267, guaranteeing dimensional and performance standards.
• Uninsulated tubular design with crimping marks for precise tool positioning.

Tips

Use a suitable crimping tool with the correct die size for 185 mm² conductors to achieve a gas-tight connection. Ensure the conductor is fully inserted into the appropriate side (aluminium into the aluminium barrel, copper into the copper barrel) before crimping. The crimping marks on the sleeve indicate the correct position for the tool.
