When the cable is stretched by external force, the tension distributed by the steel-plastic composite belt accounts for 37.7% of the force of the entire cable.Due to the fiber cable stretch, in order to ensure the fiber does not force and the integrity of the outer sheath, the main force elements need to be set aside a certain amount of stretch reserved.Therefore, in the actual production, the steel strip in the tensile process under the tension of the proportion may be higher, therefore, the quality of the steel strip, has a very important impact on the tensile properties of the cable.
