 S Span Length ar(m)    S Span Length ar(m)  
 W1 Conductor  Weight (kg/m)    W2 Conductor  Weight (kg/m)  0,3429  
 E Final Modulus of Elasticity  Es (kg/mm2)    (İlk-Son) Final Modulus of Elasticity Ei-s (kg/mm2)  
 α Coefficient of Thermal Expansion β (1/0C)    α Coefficient of Thermal Expansion β (1/0C)  

* After selecting the Pole type as Iron or Concrete in the 1st part of the table, the Ice Load Zone is selected and then the ar value is entered for the tension calculation. 

* In the second part of the table, the tension force is calculated by selecting the Temperature value and the Load Status of the Conductor(w2)
