Aluminum Connecting Sleeve / End Connector Ergom E12KA-01070100200 2ZA25

Aluminum connecting sleeve Ergom E12KA-01070100200, marked 2ZA25, is a conductive end connector designed for reliable mechanical and electrical joining of aluminum conductors. Manufactured from corrosion-resistant aluminum alloy, this sleeve facilitates crimping or compression fittings and is intended for use in cable splicing, terminations and repair works in distribution networks, overhead lines and buried installations.

Advantages

The connector provides a stable low-resistance electrical contact and mechanical retention thanks to its uniform, conductive aluminum construction. Its corrosion-resistant material ensures long-term performance in environments where moisture or oxidation may be a factor. The design is compatible with standard crimping and compression tools, enabling consistent installation quality and reduced installation time when used with appropriate equipment and conductors.

Suitable for

• Splicing aluminum conductors in overhead and underground power lines
• Repairing broken or damaged aluminum cables
• Making end terminations and mechanical joins in distribution networks
• Field installations where crimp or compression connections are required

When it may not be suitable

This aluminum sleeve is intended specifically for use with aluminum conductors; it is not appropriate for direct joining of copper conductors without a compatible bimetallic transition element. It may not be suitable where specialized insulation, sealing, or mechanical reinforcement beyond a standard crimp/compression connector is required.

Key specifications

• Material: conductive aluminium alloy with corrosion-resistant properties
• Application: crimping or compression installation for conductor splices and terminations
• Intended conductor type: aluminium conductors
• Typical use environments: overhead lines, underground cables, distribution network repairs

How to use

Select a sleeve size compatible with the conductor cross-section, prepare conductor ends by stripping and cleaning oxidation or contaminants, insert conductor ends fully into the sleeve, and perform crimping or compression with a tool recommended for aluminium connectors. After compression, verify mechanical retention and electrical continuity. Apply any required insulating or sealing materials if the installation specification calls for environmental protection.

What to consider before purchase

• Ensure the sleeve size matches the aluminium conductor cross-section and strand type
• Confirm compatibility with your crimping or compression tools and dies
• Check whether a transition connector is needed when joining aluminium to copper conductors
• Review environmental protection needs (insulation, sealing) for the planned installation

Usage recommendations

Use recommended crimping/compression tools and follow industry installation practices: prepare and clean conductors, perform controlled compression, and verify both mechanical and electrical integrity. If exposed to outdoor conditions, combine the connector with appropriate sealing and corrosion protection measures.
