Cutting a cable is the start of a series
of coordinated operations with the aim of making an electrical connection.
To allow cables with different shapes, material properties and diameters to be cut properly, cable cutting tools of an appropriate design are used. The range of these requirements extends from cutting thin, fine-wire conductors and the precise right-angled cutting of ribbon cables to cutting large diameter cables with large cross-sections as used in the power supply sector.
It must be possible to cut the cables cleanly without requiring great effort. This is guaranteed by a special blade geometry and precision-grinded and hardened blades.
High energy distribution by means of good transmission ratios or special designs to transfer the energy, such as the rim gear drive system, also allow thicker cables to be cut without requiring extreme muscle force. Low power working practice is further enhanced by ergonomically designed handles made of materials witch are easy to grip and the use of lightweight materials. A compact design also contributes to reducing the weight. This compact design also offers several benefits for using cable shears in confined areas, for example in control cabinets.
Cable shears are not suitable for cutting wire cables or steel wire. Only sturdy wire cable shears with a reinforced cutting head can be used for cutting fine conductor cables with strain-relief or cables with steel casings.
The capacity figure always refers to the
total of all wires to be cut at one stroke and not to the cross-section
of the individual cable, indicated when stating cable capcities.
