In electrical and power installations, there is no room for compromise. Whether you are building a new network or carrying out modernisation work, the durability of cable connections determines the safety and reliability of the entire system. An improperly crimped cable lug can lead to increased contact resistance, overheating of the joint and, in extreme cases, a serious failure or even a fire.
In this post, we look at why automating the cable crimping process has become the industry standard, and we present our latest series of battery crimping tools, which are transforming the everyday work of installers and fitters.
How does crimping quality affect the installation?
Correctly crimping a cable lug is not just a matter of pressing hard. The process requires:
- The right crimping force: Too little force leaves voids between the conductor strands and the barrel, which promotes oxidation and higher resistance. Too much force, on the other hand, can damage the structure of the conductor.
- Repeatable cycles: When making hundreds of connections in a single working day, maintaining identical quality with manual tools is extremely difficult and physically exhausting.
- Ergonomics and speed: In difficult conditions – at height, in cramped switchgear or in narrow cable trenches – the duration of each operation and the ease of handling the tool are crucial.
Traditional manual tools vs. modern battery technology
Classic mechanical and lever crimping tools still do the job for occasional, small tasks. On an industrial and utility scale, however, electro-hydraulic and battery crimping tools are becoming indispensable.
Key advantages of battery crimping tools
- Minimal working time: Crimping a single lug takes only 2 to 5 seconds.
- Automatic process control: A two-stage hydraulic system and automatic piston return (or automatic pressure release) ensure that every connection reaches the optimum crimping force.
- No operator fatigue: All the hard work is done by a motor powered by a high-performance Li-Ion battery, reducing the strain on the fitter's joints and muscles.
New from Electra: a new series of battery crimping tools
In response to the needs of professionals looking for reliability and maximum performance, we have introduced a refreshed line of battery crimping tools.
When designing the new series, we focused on combining mobility, high crimping force (from the compact MINI/NANO models to powerful units for power engineering work) and excellent balance.
What makes our new series stand out?
- Wide range of cross-sections: You can easily choose a model suited to your work – from small installations (from 6 mm²) to large power cables of 400 mm² and more.
- Rotating heads (360°): They provide convenient access to conductors even in the limited space of control cabinets and cable ducts.
- Long run time on a single charge: Modern 18V lithium-ion cells allow hundreds of crimps without stopping to recharge.
- Quick die change: A simple mounting system for crimping dies lets you adapt the tool to the selected lug type in seconds.
Summary: invest in convenience and safety
Choosing the right cable processing equipment is an investment that pays off in time saved, a higher standard of work and no warranty repairs.
