An electric wire performs the function of transferring energy from a generation source to a potential consumer. Therefore, they must be of high quality, have a long service life, be always operational and withstand any mechanical impact.
When choosing electrically conductive products, it is necessary to take into account such parameters as wire thickness, cross-section, braid and, of course, the number of cores (single or multi-strand). It is also necessary to pay attention to the shell, whether it protects from the aggressive environment, damage and pressure. Select cables and wires according to their purpose. The cost depends on the type, number of cores, manufacturer.
