Transmission lines are generally delta connected, hence they
don't have neutral wire.They are generally of two types
Single Circuit, Double Circuit lines.Single circuit consists
of 3-Phases R,Y,B.Double Circuit just consists of 2 Single
circuit lines.For economizing the cost of transmission lines
it is tried to use as many Double Circuit towers as land
cost to build these towers are increasing day by day.Even 4
circuit towers are also in use at places which have 4x3=12
conductors.Above stands for 33KV,132KV & 220KV transmission
lines. The conductors used are ASCR(aluminum Conductor steel
reinforced) or AAAC(All aluminium alloy conductor).
For 400KV lines each phase consists of 2conductors generally
known as bundled conductors (ACSR/AAAC -Moose variant)i.e
total 6 conductors for Single ckt., 12 conductors for Double
Ckt.

Generally HV transmission lines are like SUSPENSION towers they are very high cost to transmit the supply, In that case it is good to put 6 conductors and also if u saw that means it is generally construct like that on each side with porcelian insulators hanging with conductors....I think the conductor use the HV transmission lines are ACSR-Aluminium conductor steel reinforced....

1000 W bulb takes 4.16 Amps at 240 volt then what will be the KWH & if i am using 1000 W bulb at 180 Volt the amps will be 5.55 then what will be KWH????????????????

I know during Surge Impedance Loading maximum power is transferred through a transmission line and also Sending end voltage becomes equal to Receiving end voltage i.e Vs=Vr so my question is if both end voltages are equal then how current travels in such line hence how power is transmitted because flow of current needs Potential difference??
