Design and installation method for power wire with transition point temperature characteristics

The invention discloses a design and installation method for a power wire with transition point temperature characteristics, belongs to the technical field of installation of overhead wires, particularly relates to a design and installation method for a power wire with transition point temperature characteristics and provides the design and installation method for the power wire with the transition point temperature characteristics and a good installation effect. The method comprises the steps as follows: the length of the wire is l in a tension-free state at a manufacturing temperature t ; the wire is installed; the tension of the wire is T, the temperature is t and the length is L; a formula as shown in the specification is obtained according to the hooke's law of elastic deformation in material mechanics; in the formula, epsilon is the elongation of the unit length of the wire caused by the tension and a temperature difference; E is an integrated elasticity modulus (N/mm ) of the wire; A is a sectional are
