Lead is vertical always than carrying g vCarry a g with the level ratio hBe respectively:
g v＝g?′cosη
g h＝g′sinη (4-6)
5) always carry the calculating icing than carrying from anharmonic ratio according to lead is vertical than carrying with lead.
By vertical direction always than carrying a g v=g Or+ g i, wherein lead carries g from anharmonic ratio OrBe known conditions, then wire icing is than carrying g iFor:
g i＝g v-g or (4-7)
6) calculate wire icing weight according to wire icing than carrying.
G＝g iAL′ (4-8)
In the formula (4-8),
G is a wire icing weight;
g iFor the wire icing ratio carries;
A is a sectional area of wire;
L ' is the length of span inside conductor.
L ' can use following formula to calculate:
