Why aren't the cables between pylons covered in plastic?

Answer 1

Household wires and electricity flexes are covered in plastic so that you do not touch the metal core by accident as it carries the electricity.

But the overhead lines carried by pylons and in substations are not insulated at all as any way they are out of reach and insulating them adds up unnecessary costs. Pylons have ceramic or glass insulators to support the overhead lines so that electricity is kept away from the pylon itself.

Answer 2

There are many plastic wires, including laundry lines, fishing lines, and lawnmower lines (for hand lawnmowers).

For many purposes lines are not made out of plastic, because plastic stretches more than rope.

Answer 3

Cables between pylons are not covered in plastic because it would add additional weight, cost, and maintenance to the infrastructure. Additionally, covering the cables would make it harder to inspect for wear and damage, which could compromise safety.

Answer 4

Because then the plastic may burn

Answer 5

So they can save money
