High voltage transmission line insulator are also made of glass.
Yes, that's because the voltage output of an alternator is restricted by the number of windings that can be slotted into its armature, restricting its output voltage to just 25-30 kV, which is far too low for transmission purposes.
The length of the wire causes resistive load to be distributed along line. This accumulated resistance causes the voltage drop.AnswerThe voltage drop along a high-voltage transmission line isn't large in relation to the operating voltage of the line. One of the advantages (there are many) of using high voltages is that, for a given load, the line current is relatively low -so the voltage drop along the line is also relatively low.
A high voltage like 750kV is used in transmission lines because this reduces the current in the wires for a given amount of power. A reduced current will reduce the power lost in transmission (I^2R).CommentFar more importantly than reducing line losses, it reduces the voltage drop along the line which would, otherwise, be enormous!

750kv
Phase to Phase voltageCorrection to the above answer:There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.
Transmission and distribution voltages are normally expressed in terms of line voltages, so the answer is that the figure you quote is a line voltage. Incidentally, do you really mean 230 megavolts for a transmission voltage?? And the symbol of kilovolt is 'kV', not 'kv'.
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.

Transmission Line Charging To initially charge the transmission line, the generator voltage stably controlled from 30% of the rated voltage to 110% of the rated voltage by using AVR. The change-over switch (43CH) for initial transmission line charging is mounted on the operator's desk in the main control room.This Voltage Changes are required because of the Stray capacitance effect at the charging and boosts the Voltage at the other end and the inductance of the line drops the Voltage soon after charging
Yes. Because... If we connect an alternator to a transmission line of high capacitance the line voltage will increase and caused a line voltage difference, which does not satisfied the condition of parallel operation of same voltage rating. [By Akhtaruzzaman08]

Well, there is no way of doing it without an overhead or underground transmission line.
approx. 1000 volts
Because the value form factor is 1.1 that's why transmission line voltage is always in a multiple of eleven.
