Ergom at ENERGY TECH 2026: How to Effectively Connect Aluminum Cables
At the ENERGY TECH 2026 conference, Ergom experts presented two technologies for connecting cables using cable connectors.
Ergom at the ENERGY TECH 2026 Conference
From May 6–8, 2026, we participated in the ENERGY TECH 2026 – Innovative Solutions for Industry conference, an event dedicated to professionals from the automation and power engineering sectors. The conference aimed to bring together experts from various industrial fields while promoting practical solutions that can be successfully applied across the electrical engineering industry.
Which Technologies Are Best for Connecting Aluminum Conductors?
Ergom experts were invited to deliver a presentation entitled "Crimped or Mechanical Cable Connectors?" During the session, we demonstrated two technologies for connecting 120 mm² aluminum conductors, with particular emphasis on selecting the appropriate cable connectors and performing the connection correctly to ensure high-quality, reliable, and long-lasting performance throughout the power distribution process.
ZAE ERGOM Laboratory Research Delivers New Technical Insights
The ENERGY TECH 2026 conference provided an excellent opportunity to exchange knowledge, discuss industry challenges, and present the latest research results from the ZAE ERGOM In-House Laboratory. These findings offer valuable technical insights for industry professionals while also creating opportunities for meaningful business networking.
The laboratory test results, available in the presentation (link), demonstrate which connection technologies deliver the best long-term performance under operational conditions.
Table 1. Summary of the Research on Aluminum Conductor Connections
| Type of connector dedicated to cable with 120mm² core | The cross-section and design of the connector are adapted to one cross-section of the wire | The cross-section and design of the connector are adapted to several wire cross-sections. | Installing the connector using a dedicated tool and crimping die | Even distribution of the cable core inside the connector | The need to reshape sector veins in a circular manner | Installing the connector using a flat, socket or Allen key | Installing the connector using a hand screwdriver with adjustable torque |
