Klauke VHR185 Tin-Plated Aluminum Compression Splice for Copper to Aluminum Conductors 185 mm²

The Klauke VHR185 is a high-quality compression splice designed for the reliable and permanent connection of copper and aluminum conductors. Manufactured by Klauke, a leader in connection technology, this splice ensures a secure, low-resistance joint that meets the demands of professional electrical installations. The VHR185 is pre-filled with contact grease and features a tin-plated inner surface on the copper side, providing excellent corrosion protection and long-term stability.

Advantages

This compression splice offers several key benefits: it enables a gas-tight and vibration-resistant connection between dissimilar metals (copper and aluminum), preventing galvanic corrosion. The pre-filled contact grease ensures optimal conductivity and simplifies installation. The hexagonal crimping profile provides a uniform and reliable crimp, and the crimping markings on the sleeve guarantee correct positioning for consistent results. The tin-plated inner surface on the copper side enhances corrosion resistance and ensures a stable connection over time.
