Electrical connections are the backbone of any electrical installation, and the quality of their crimping plays a crucial role in the safety and performance of the system.
1. cleanliness before crimping: the basis for success
Before the actual crimping process begins, it is crucial to ensure that all components are spotlessly clean. Careful cleaning of the conductors is essential to ensure their metallic purity. Particular attention should be paid to the aluminium cables, which must be checked for visible layers of oxidation, and the use of high-quality stripping pliers is the key to perfect stripping of the cable. Ensure that the conductor is not damaged in the process. The length of the stripped section should be around ten per cent longer than the insertion dimension of the cable lug or connector in order to allow for possible changes in length due to crimping.
2. tool selection and system coordination: uniform quality for optimum connections
With prepared connectors and clean conductors, the actual crimping can begin. The selection of suitable tools plays a decisive role here. Cable lugs can only be processed professionally and cleanly if the right tool is used. You have the connectors, we have the right tool! The manufacturer of the connectors specifies how to crimp - i.e. which crimping form is the right one and how often the connector should be crimped. Simply let us know which crimping insert type you need and which type of cable with which maximum cross-section should be crimped. We will be happy to advise you on suitable tools available from us.
3. the right crimping sequence: precision for long-lasting connections
A decisive factor is the exact sequence of crimping. In the case of cable lugs, the first crimp is made on the connection side and then moves in the direction of the cable. In the case of connectors, on the other hand, the first crimp is carried out in the centre. This precise sequence is crucial to avoid material expansion and minimise cracking. Make sure that the crimping process is carried out to completion. Complete pressing is essential, as the necessary compression of the pressing material is only achieved at the end of the pressing phase. This is the only way to ensure correct crimping.
Conclusion: Perfect cable crimping for safe electrical installations
The quality of electrical connections begins with preparation and the selection of the right tools. A careful approach not only achieves clean and efficient results, but also ensures the safety of electrical connections. Perfect cable crimping is therefore not just a craft, but also an art that should be carried out with precision and care.
