to send power through them so that electricity can get to your home
One type of insulator is ceramic, these were used in the older power lines and the newer styles are glass
Power lines are used to transport or transmit electrical energy from the electrical generator to the customers. Power lines are important for they help factories, commercial buildings and residences have electrical energy.
Used power resources
there are no power lines in heaven
Power lines are used to move electrical energy from one place to another. In a simple system the power lines would connect a generator to a set of customers. For large amounts of energy thick overhead cables are used, supported by pylons. The largest pylon circuits can carry enough power to supply over a million homes.
Soil, waste ,storm
No, not with current technology.
YES BUT INSULATED CABLE ARE USED

You will need to look up cabling/wiring codes.Is it:Telephony,Audio distribution,110 volt power lines, orHigher voltage power lines?
Weight and cost factor.
The large glass insulators are easy to mould, and are strong, well able to insulate the pylons from the high voltage the cables are designed to carry.
