Save on cables with the price check

Single-core/Multi-core motor cables

Broken cores or defective shields are feared in industrial applications. This often causes machines to come to a standstill. igus designs its chainflex cables with mechanically high-quality copper conductors in an optimised pitch length to prevent such shutdowns. This core structure ensures a high load capacity compared to conventional motor cables. From a core cross section of 10mm², it is advisable to switch to single cores for energy chain systems, as these can be used in a smaller installation space, which also benefits the mechanical design of the entire energy chain system.

Cost-effective and space-saving are the two main features of a single core compared to a multi-core motor cable. Single cores can be produced much more cost-effectively than the four-core alternative. The smaller diameter means that faster processing speeds can be achieved, which ultimately has a positive effect on production costs.

In addition to the costs, the issue of saving space in tight installation spaces is particularly important. Both factors make the use of single cores in energy chains particularly attractive in a wide range of applications.

Application examples from practice

In addition to the price advantage of around 30%, the radius is also reduced. This leads to a reduction in installation space of over 50%. Another advantage of single cores in the energy chain is that the cables can be better distributed in the chain, which also increases durability.

Our own test laboratory in Cologne has been carrying out hundreds of cable tests per year for 25 years. Many industrial machines need small bend radii of the motor cable: a bend radius of up to 5 x d can also be guaranteed. A service life guarantee of 36 months and up to 10 million double strokes can be provided based on the experience gained in the test laboratory.
