Wire Length distortion

Hello, 

Is there a way to simulate interconnected wires and their loads while keeping wire lengths constant? I have tried this in kangaroo 2, but when I apply a Load Force it changes my Angle and Length(Line) after running through the solver. I have tried various Strengths for both these, but even at 100 there is still distortion. 

Attached is my gh file and an image of the dimension distortion. 

Thanks!
