ALPAR two-sided piercing connector AL-CU 16-95/1.5-95 (Z2082) for AL/CU conductors

ALPAR two-sided piercing connector AL-CU 16-95/1.5-95 (Z2082) is a mechanical connector for creating a reliable electrical joint between aluminum and copper conductors of specified cross-sections. The device is designed to pierce conductor insulation and make stable contact without the need to strip insulation, enabling faster and safer installation in low-voltage distribution, overhead and service lines. It is suitable for tapping, branching and repair work where AL and CU conductors of the corresponding sizes must be connected.

Advantages

The connector provides a gas-tight mechanical and electrical connection between dissimilar conductors by using piercing teeth that penetrate insulation and secure the conductor cores. Its two-sided design allows connection of conductors on both sides with consistent contact pressure. The product reduces installation time by eliminating the need for insulation removal and minimizes the risk of conductor damage. Construction materials and geometry are chosen to ensure long-term conductivity and mechanical stability in typical outdoor and indoor power distribution conditions.

Suitable for

• Tapping and branching of low-voltage overhead lines
• Service line connections between aluminum and copper conductors
• Field repairs and temporary or permanent joints in distribution networks
• Situations where insulation should remain intact during connection

Key specifications

• Compatible conductor cross-sections: aluminum side 16–95 mm², copper side 1.5–95 mm²
• Two-sided piercing design for AL–CU conductor connection
• Insulation-piercing teeth for contact without stripping
• Mechanical construction providing consistent contact pressure
• Intended for low-voltage distribution and overhead/service lines

How to use

Position the connector so the appropriate conductor runs are aligned with the designated aluminum and copper sides. Place the connector over the insulated conductors, ensuring the insulation-piercing teeth contact the conductor path. Apply the recommended mechanical force using the specified crimping or pressing tool until the connector is fully engaged and a firm mechanical and electrical contact is established. Verify the connection visually and, if required, measure continuity or resistance to confirm proper contact.

Usage recommendations

Use tools and installation methods compatible with insulation-piercing connectors and follow local electrical codes. Avoid repeated repositioning after the teeth have pierced insulation to prevent conductor deformation. Where exposed to outdoor environments, consider additional protective measures if required by the installation, such as insulation sleeves or sealing against moisture. Confirm conductor sizes before installation to ensure compatibility.
