What is the difference between ampacity and temperature of overhead lines?
Homework Answers
Step 1
The temperature of the overhead transmission line is defined as the
heat produced in the line by transmitting the electric power from
one place to another.
usually, the temperature rating of the overhead transmission line
is 60-degree Celcius.National electrical code 310.10 defines the
temperature rating of overhead transmission lines.
Step 2
The ampacity of the overhead transmission line is defined as the
maximum current in amperes that a conductor can carry continuously
without exceeding temperature rating of the conductor.
The United States National Electrical Code, Table 310.15(B)(16) specifies the ampacity of transmission line .Acording to this code ampacity of overhead transmission line is 50 A.
