What do you mean by 30 7 ACSR conductor?
In a 30/7.
ACSR conductor the aluminum and steel strands are of the same diameter.
In a 30/19.
ACSR they are not.
Within the core or within the outer layers, however, the number of strands always increases by 6 in each succeeding layer..
What is lay ratio of conductor?
LAY RATIO: The lay ratio (Ratio of the arial length of a complete turn of the helix formed by an individual wire in a stranded conductor to the external diameter of the helix) shall be within the limits given below: a) Aluminium conductor steel re-inforced. Lay ratio for.
What is ACSR conductor & type?
Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium, chosen for its good conductivity, low weight, low cost, resistance to corrosion and decent mechanical stress resistance.
How much current is in 11kV line?
An 11 kV distribution circuit may carry 150 A in each of its three phases, thus transmitting a power of 3 MW. A 400 V final distribution circuit may carry 200 A in each of its three phases, thus transmitting a power of 150 kW.
Is 480V AC or DC?
The voltage between either of the actives and the neutral is 240V while the voltage between the two active conductors is 480V. It is the a.c. equivalent of the three-wire d.c. system. It facilitates the supply of larger loads or loads at greater distances from the transformer than the single-phase 2-wire system.
What is the meaning of 33 11 kV?
Thus, when a substation is of rating 66/11 kV, means substation has been designed to receive 80 MVA on 66 kV and it will distribute the received power on 11 kV. Again, substation of rating 33/11kV means, the substation has been designed to receive 5 MVA of power at 33 kV and it will distribute the same on 11 kV.
What are 3 types of insulators?
List the Different Types of InsulatorsSuspension insulators.Pin insulators.Strain Insulators.Stay Insulators.Shackle Insulators.
Why are ACSR conductors named after animals?
Originally Answered: Why are ACSR conductors named after animals- like Moose, Dog, Peacock, Hen, Zebra etc. ? These nomenclatures are for easy reference and remembrance.
What are 3 types of conductors?
Of all the materials, the top three are silver, copper and aluminum. Silver is known to be the best conductor of electricity but it is not widely used for economic reasons. It is only used for special equipment like satellites. Copper, though not as high as silver, also has high conductivity.
How many types of conductor are there?
Following are four common types of overhead conductors used for overhead transmission and distribution to carry generated power from generating stations to the end users. Generally, all types of conductors are in stranded form in order to increase the flexibility.
How many volts is a 3 phase line?
For three-phase, you connect line 1 to line 2 and get 208 volts. At the same time, you [can] connect line 2 to line 3 and get 208 volts.
What is Zebra conductor?
Standard Sizes of Conductor for Lines of Various Voltages: ‘Zebra’ ACSR having 7-strand of steel of dia 3.18 mm and 54-Strands of Aluminium of dia 3.18 mm. (iii) For 400 KV lines. : Twin ‘Moose’ ACSR having 7-Strands of steel of dia 3.53 mm and 54-Strands of Aluminium of dia 3.53 mm.
Is Diamond a good conductor of electricity?
Diamonds do not conduct electricity. Many engineers once believed diamonds could not conduct electricity due to a tetrahedron structure made by covalent bonds between carbon atoms, which doesn’t allow for free electrons to carry current.
What is Moose conductor?
The moose conductor is a very popular type of aluminum conductor steel reinforced. It is clear that the aluminum and steel are the main raw materials. This conductor consists of 54 stranded aluminum of 3.53mm diameter and 7 steel strands of 3.53 mm.
Which conductor is used for transmission line?
The most common conductor in use for transmission today is aluminum conductor steel reinforced (ACSR). Also seeing much use is all-aluminum-alloy conductor (AAAC). Aluminum is used because it has about half the weight and lower cost of a comparable resistance copper cable.
What is Wolf conductor?
Wolf conductor is a special type of aluminum conductor steel reinforced. It is used as bare overhead transmission conductor. And as primary and secondary distribution conductor and messenger support.
What is the best conductor?

What is a Class 1 conductor?
Conductors of different circuits. Class 1 circuits can occupy the same cable, enclosure, or raceway without regard to whether the individual Class 1 circuits are AC or DC, provided all the Class 1 conductors are insulated for the maximum voltage of any conductor in the cable, enclosure, or raceway.
Is salt solution a conductor?
This is because salt water is a good conductor of electricity which makes ocean water a resource for renewable energy. Salt molecules are made of sodium ions and chlorine ions. … These ions are what carry electricity through water with an electric current. In short, salt water can help to produce electricity.
What are 5 good conductors?

What is Panther conductor?
ACSR panther conductor belongs to the BS-215 standard acsr conductor. Its aluminum area is 200 mm2. It strands 30 aluminum, which the diameter is 3 mm. There are 7 steels, which the diameter also is 3 mm. … In the normal situation, the current rating of panther conductor is 421 A.
