Guyed wires are safely considered to be one of the most important bases of a mast or tower. In fact, the stability of a mast or a tower—fully guyed or partially guyed—depends on the guyed wires to a greater extent. Obviously, the manufacturers of guyed wires pay a lot of attention to the making of a guyed wire.
An important attribute of a guyed wire is its elasticity or stiffness. In other words, elasticity of a guyed wire can be defined as the propensity of the guyed wire to get deformed when a certain degree of load or pressure is applied on the wire. Conversely, stiffness of a guyed wire is defined as the rigidity of movement of the wire when a certain degree of load or pressure is applied on the wire.
Reputed manufacturers all over the world consider that the higher the elasticity of a guyed wire, the less is the stability of the supported mast or tower and vice versa. Conversely, rigidity in guyed wires is considered a desirable attribute.
Manufacturers of guyed wires maintain that just about every material they use for making wires is elastic in varying degrees. According to the manufacturers, elasticity of a guy can be of the following types primarily:
- Elastic deformation: A wire deforms elastically when a load or pressure is applied on it and it moves back in its original shape after the load or pressure is withdrawn.
- Plastic deformation: A wire deforms plastically when a load or pressure is applied on it and it is unable to regain its original shape. The wire then attains a permanent deformity.
- Combination deformation: A wire can deform both plastically and elastically when a load or pressure is applied on it and it is partially able to regain its original shape.
Each wire that is used for guyed towers has a yield stress. Yield stress is defined as the maximum limit till which a wire will not deform under load or strain. The manufacturers of wires all over the world typically try to put in as much yield stress as they can in order to increase the resistance of the wires.
Though there are other factors that determine the strength of a wire, its elasticity is primary and must be strengthened so that the guyed towers are adequately stable. In addition to improving elasticity of the wires, the manufacturers improve the modulus of the wires too.
