What is ACSR conductor?
Aluminium Conductor Steel Reinforced
Outer strand - Aluminium
Center strand - steel
ACSR having high conducting capacity usually used in overhead transmission line to carry high voltages.
"Dog" is the code name for a specific type of conductor ACSR conductor - 14.2mm in diameter with 7 small (1.57mm) strands of steel and 6 large strands (4.27mm) of aluminium, and can carry up to 455A of power. ACSR conductors are named after animals, with the larger/smaller the animal, the large/smaller the conductor is - a Dog conductor is larger than a Mole conductor, but smaller than a Zebra conductor.
The wire you refer to is ACSR. Aluminium Conductor Steel Reinforced. The steel core is used to give the wire structural strength. When the conductor is spanned across great distances between poles or towers the total weight of the conductor between spans would be too much for just the aluminum wire to support. The steel center core is also known as the cables messenger.
-The tension of the cable (the tighter, the less sag, but this can cause other problems if too tight) -The temperature outside (the higher the temperature, the more it will sag) -The amount of current flowing through the cable (the more current, the hotter the conductor will get = more sag) -The type of cable (aluminimum will sag more than copper; ACSR will sag less than straight aluminimum).
That because copper is a good conductor. <<>> In nearly all cases copper is not used to carry electricity from the generating power plants to the home. Aluminum is used, to be completely accurate ACSR. Aluminium conductor steel reinforced. Aluminum is much lighter than copper and can span longer distances between support towers. Copper conductors to carry electricity to homes and building does not start until the service mast head. This is the connection to…
Both the panther and zebra conductors are ACSR ( aluminium conductor steel reinforced). The conductors are named depending on the current and voltage rating requirements. Panther conductors are smaller compared to Zebra conductors. The current carrying capacity at degrees ambient temp of panther is : 482A and for Zebra is 736A. The diameter of panther is 21mm and Zebra is 28.62mm.
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…
