Armor designs offer a wide range of electro-mechanical cable properties

By combining various materials and configurations a broad range of electromechanical cable characteristics is currently available. Because of the combination of high strength with excellent mechanical protection for the electrical core, steel contrahelically armored cables have most frequent use. Other steel strength member configurations are available to vary cable characteristics such as weight and corrosion resistance. When mechanical protection of the electrical core can be sacrificed, the weight and corrosion resistance advantages of the new high strength fibers can become available.
