Hexagonal crimping crimping profile

=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.

Hexagonal crimping is typically used for copper compression cable lugs according to DIN 46235 and aluminium compression cable lugs according to DIN 46329. This crimping profile can also be used to crimp solid cables with full tension.

The major benefit of hexagonal crimping relates to the central application of force, which is applied in equal measure from all sides and has an effect over a large contact surface. The individual stranded wires of the conductors are deformed as a whole in equal measure without being damaged.

The result is good mechanical stability and a secure connection. Due to the consistent crimping involved, hexagonal crimping is also suitable for the medium and high-voltage range.

The alternative is manufacturer-dependent hexagonal crimping

In addition to standardised hexagonal crimping, so-called manufacturer-dependent hexagonal crimping is also allowed in the copper sector for conductor classes according to DIN 60228, class 2. This crimping has been specifically developed for the tubular cable lugs on sale. As a result, it is essential you always revert to a manufacturer-specific system.

Freedom of choice: wide or narrow crimping

You can use wide or narrow crimping depending on the tool you are using. This will primarily depend on the cross-section and power of the tool in question. It is possible, for example, to use narrow crimping to crimp a 300 mm² tubular cable lug with a six-tonne battery-powered hydraulic tool. However, this will require several crimpings, something that will of course involve additional time. Therefore, you must take care that you make the right selection when purchasing a tool and ensure it is matched to the range of applications.
