Short Circuit Force Calculation on Gantry

[Linspire]

Dear all,

Anyone here can do the calculation based on IEC 865 Part 1 1993 ?

I would like to request technical details for

i. 45M Span Line Entry - Quad Drake ACSR;
ii.45M Span Jack Bus - Twin 1267 Sq.mm AAC;

 

[Linspire]

Anyone here guide me the technical for those conductors ?

Guys, after calculated value for short circuit force such as

i.tensile force due to short circuit,
ii.tensile force due to drop,
iii. tnesile force caused by pinch effect,

How do you guys justify the calculation value is acceptable ?

Guys,

How you guys calculate value for Tpi which is parameter for calculating Pinch Force (Fpi), the factor V2.
As I know, V2 value can be get it directly by referring figure. But I would like to know the equation for calculating Tpi.

I didn't calculate using this but I think these links may be useful:
See: IEC 60865-1 Annex A (normative) A.6 Figure 8[p.109] A.7 Figure 9[p.111]
