Crimping profiles at a glance

Good crimping makes the perfect connection: an overview of crimping profiles

This issue appears complicated at first glance, but a second glance shows that this is not really the case at all. Electrical engineers are confronted with numerous different types of conductor in their day-to-day work and these each demand different cable lugs and connectors for correct processing. Once the choice of matching components has been made, a decision must then be made as to which crimping profile will give the most secure connection. Different crimping profiles are suitable depending on the material, design and intended use: 

Hexagonal crimping: for aluminium and copper

Hexagonal crimping is the most frequent type of crimping for cable lugs and connectors. Hexagonal crimping is one of the more traditional crimping profiles. It is most frequently used in practice, as it is suitable for both copper and aluminium conductors. With this crimping profile, the single strands are deformed over a large horizontal area.

Indent crimping: for aluminium and copper
Indent crimping creates a permanently secure and deep-rooted connection. Indent crimping is one of few crimping profiles which require no cross-section dependent pressing inserts. This allows, for example, the Klauke EKM 60 ID to achieve a crimping range of 10-240 mm² with copper and 50-240 mm² aluminium.

Quad-point indent crimping: for copper
The advantage of quad-point indent crimping is the centric force and simple processing. This crimping profile is suitable for tubular cable lugs and connectors with cross-sections of 10 mm² to 300 mm² in combination with conductor types of DIN EN 60228 classes 2, 5 and 6.

Notch crimping: for copper
Notch crimping is the oldest and probably also the crimping profile that is originally most well-known in electrical engineering. Currently it is used in control cabinet construction up to 1 kV. It is set apart by a deep point-specific deformation of the cable lug. However, it is only suitable for processing copper.
