The k factor, or thermal conductivity, for copper at 68 degrees Fahrenheit (20 degrees Celsius) is typically around 401 W/m·K (watts per meter per kelvin). This value can vary slightly depending on the purity of the copper and the specific temperature conditions, but it remains relatively consistent for standard applications. Copper's high thermal conductivity makes it an excellent choice for electrical and thermal applications.

Who many amps are needed to feed a 600 v to 480 v 3 phase 70 KVA transformer?

The equation for amperage when the kilowatts are known is Amps = kVA x 1000/1.73 x Volts.The electrical code states that a feeder for a transformer has to be rated at 125% for the primary and secondary load amperages.The amperage on the primary needed to supply a 70 KVA three phase transformer to its full capacity at 600 will be 68 amps. 68 x 125% = 85 amps. A #4 copper conductor with an insulation factor of 90 degrees C is rated at 95 amps.The amperage on the secondary needed to supply a 70 KVA three phase transformer to its full capacity at 480 will be 84 amps. 84 x 125% = 105 amps. A # 3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps.
