What is the ampacity of gold silver copper and aluminum?
The ampacity for copper is 1000A per square inch, in some places is 700A psi.
What ACSR conductor is named after an animal?
acsr means all alluminum steel reinforced , it means it has a steel conductor inside for reinforcing just as animals has backbone , so names of the animals & birds names with backbone are used for ASCR. AAC, All alluminum cable , the names of insects used
The larger the conductor the Higher the resistanc Lower the ampacity Higher the voltage Lower the resistance?
No. The larger the conductor the lower the resistance and the higher the ampacity.
What is the line loss of 4 ACSR when the voltage is 14400 volts?
It doesn't really matter what the distribution voltage is. Line loss is dependant on the current through the conductor. #4 ACSR (aluminum conductor, steel reinforced, used in electrical transmission), has a typical resistance of 0.399 ohms per 1000 feet, and a maximum ampacity of 140. At max load, the I^2 * R loss would be about 7.82kW per 1000 feet of cable, or about 123kW per mile of 3-phase distribution. A 14,400 volt 140A system delivers about 3.48MW at unity power factor, so this represents about a 3.5% loss per mile, which is why 14.4kV is used for distribution, not transmission. Most likely, the cable would reach thermal limit well before 140A, and so would never be loaded to the max ampacity, so this is the theoretical max. At a more reasonable current, line loss would be correspondingly less.
What ACSR conductor is used for 33kV transmission line?
Single Circuit PantherACSR Conductor
Acsr squab conductor properties?
squab
What determines the ampacity of wire?
Conductors must have an ampacity not less than the maximum load that they are supplying.
What determine the ampacity of a wire?
Conductors must have an ampacity not less than the maximum load that they are supplying.
What is an ampacity?
An ampacity is the root mean square of the electrical current which a device can carry within a specific environment, measured in amperes.

No. The larger the conductor the lower the resistance and the higher the ampacity.
What is a ACSR Conductor in a substation?
ACSR stands for aluminum conductor, steel reinforced. This type of conductor is used for transmission lines that are strung between poles or towers. The aluminum is used for its lower resistance, and the steel provides the structural strength.
What is Wire ampacity?
It is a North American electrical term. It is a combination the words amp and capacity rolled into one word "ampacity". When talking about how much amperage a wire can legally draw, it is referred to as the wire's "ampacity".
What is the ampacity of a NM-B cable?
Allowable ampacity for 10-2 copper NM-B is 30 A.http://www.cerrowire.com/default.aspx?id=46
