Straight Tower Swing Angle (直线塔摇摆角)

Calculates the wind-induced swing angle of suspension insulator string on a straight transmission tower under three conditions: working voltage, internal overvoltage, and external overvoltage.

⚙ Input

Insulator string weight G (kg) Number of insulator pieces n Single piece wind area A (m²)

Conductor weight per unit length g (N/m) Number of sub-conductors n

Horizontal span Lh (m)

Weight/vertical span Lv (m)

Evaluated for the three design conditions (working voltage, internal and external overvoltage). String wind pressure F j = A·0.625·v².
