## Summary description

ALPAR two-sided insulation-piercing clamp Z2081 for Al-Cu conductors with a cross-section range of 16–120 mm². Designed to create electrical connections without stripping conductor insulation, it mechanically pierces insulation to contact aluminum and copper cores. Suitable for power distribution, branch connections and repairs in electrical installations where reliable conductive contact and mechanical retention are required.

## Long description

ALPAR two-sided insulation-piercing clamp Al-Cu 16–120 mm² model Z2081 is a mechanical connector designed for making electrical connections between aluminum and copper conductors without removing conductor insulation. The clamp features a piercing mechanism that creates secure electrical contact by penetrating insulation and gripping conductor cores, providing a reliable joint for power distribution lines, branch taps and repair work in low- and medium-voltage installations.
Advantages
The clamp delivers consistent insulation-piercing contact for both aluminum and copper conductors within the 16–120 mm² cross-section range, eliminating the need for stripping and reducing installation time. Its two-sided design ensures mechanical retention and stable electrical conductivity under typical thermal and mechanical loads. The product is suitable for repeated mechanical handling during installation and offers a compact form factor for use in confined spaces.
Suitable for
Power distribution main lines and lateral taps
Branch connections in overhead and underground networks
Repair and maintenance of insulated conductors
Temporary and permanent connections where stripping is impractical
Key specifications
Compatible conductor materials: aluminium and copper
Conductor cross-section range: 16–120 mm²
Connection type: insulation-piercing (mechanical piercing) on both sides
Suitable for insulated round conductors without prior stripping
Mechanical retention provided by clamping jaws and piercers
Compact dimensions for use in limited-access locations
How to use
Position the clamp so that each conductor to be joined sits in the designated channel, ensuring correct alignment of aluminium and copper conductors. Close the clamp and apply the recommended torque or mechanical force to activate the piercing elements until the insulation is penetrated and the jaws secure the conductors. Verify firm mechanical fixation and continuity with appropriate testing equipment before re-energising the circuit. Follow local electrical codes and safety procedures during installation.
Usage recommendations
Use the clamp only on conductors within the specified 16–120 mm² range and on intact insulation. Do not reuse a clamp that shows visible damage to piercing elements or jaws. For long-term outdoor installations, assess environmental exposure and, where required, apply additional protective measures against corrosion and mechanical stress. Perform a continuity and torque check after installation to confirm reliable contact.
