Klauke 370R12 Bimetallic Compression Joint Al-Cu 185 mm², Pack of 5

Connecting aluminum and copper conductors in medium voltage networks is a challenge: direct contact causes galvanic corrosion, leading to increased resistance, overheating, and potential failure. The Klauke 370R12 bimetallic compression joint solves this by using a friction-welded aluminum barrel and copper insert, providing a safe, durable transition between aluminum and copper cables of 185 mm² cross-section.

Who is it for

Electrical installers, utility technicians, and maintenance crews working on medium voltage cable connections up to 30 kV. Ideal for applications where aluminum and copper conductors must be joined reliably, such as in power distribution, transformer connections, and cable repair.

Main features

• Bimetallic design: aluminum barrel with copper insert, friction-welded for a permanent, corrosion-resistant bond.
• Suitable for both aluminum and copper conductors with cross-section 185 mm².
• Compression connection method ensures a gas-tight, low-resistance joint.
• Tin-plated copper part for enhanced corrosion protection and conductivity.
• Inner diameter 16.3 mm accommodates standard conductor sizes.
• Complies with DIN EN 61238-1 for compression and mechanical connectors.
• Pack of 5 pieces for convenient job-site supply.
