recordAnnealed_Al_500

Annealed Al cable - AWG 500

Extends from Buildings.Electrical.Transmission.MediumVoltageCables.Generic (Data record for a generic medium voltage cable).

Information

Annealed aluminium cable with a cross-sectional kcmil 500 (thousand of Circular Mils). This type of cable has the following properties

Rdc  = 0.116142e-3 // Characteristic DC resistance at T = T_ref[Ohm/m]
T_ref= 298.15      // Reference temperature of the material [K]
d    = 20.066e-3   // Inner diameter [m]
D    = 37.592e-3   // Outer diameter [m]
Amp  = 450         // Ampacity [A]
