| Abstract: | This paper gives the calculating formulas for the pre-tension of the wrapping wireswhich considers the effects of the voids in the main cable, and discusses the selection of the timeand the technical requirements for wrapping the main cable with steel wires. The example showsthat the main factors affecting the pre-tension of the wrapping wires are the ratio of voids of themain cable, the diameter and the modulus of elasticity of the wrapping wires. |
