Control cables are an important and integral part of various electrical systems as they provide control of transmission signals and control for machines and equipment. Control cables are designed, constructed, and their performance is measured by criteria outlined in IEC 60227 and UL 1581. These international standards ensure appropriate levels of environmental protection and safety assurance for the devices. These standards have to be known by engineers and project managers because they make the selection of cables that guarantee compliance with different requirements for usage and operational performance.
