The best tips for efficient conductor cutting
In order to be able to manufacture secure connections, it is particularly important to ensure a smooth and straight cut that will not deform or damage the conductor when processing conductors. Every user will indeed have his or her own favourite technique to wire strip conductors. However, in principal, there is a distinction to be made between two cutting techniques, namely shearing and pinching, also known as tapered cutting. Both techniques are in accordance with DIN 8588.
When shearing, the cable is split through two cutters moving past each other. This technique is used in particular when wire stripping cables, wires and conductors made of copper and aluminium. Premium quality wire stripping tools are fitted with an integrated cutting unit that has been specifically adapted for these materials. This allows you to cut the material efficiently with little force that is also gentle on the tool being used.
However, pinching is well suited if you are severing hard metals. This technique involves pushing apart and separating the cable through one or two wedge-shaped cutters.
The following point applies to both cutting techniques: in order to ensure you can work quickly and safely, the cutting unit should be adapted in the most ergonomic way.
These risks can be countered by choosing modern tools that cater for specific requirements. These tools adapt automatically to the respective cross-section and insulation thickness, thus enabling optimum stripping of the cable. In cases where the insulation is extremely thick or very thin, special pliers have also been developed that have the automatic self-setting as well as the option to manually adjust the cross-section. This ensures maximum safety in all eventualities and caters for all requirements. However, if the insulation is extremely thick, it is recommended you perform a wire stripping test on a sample cable.
