conductor

Copper conductors are surrounded with many layers of paper insulation.

Metals are conductors, meaning their electrons are loosely bound to their atoms and move freely in response to electric fields.

These high voltage conductors connect to a series of some or many pieces of equipment before heading out to their next step in the power grid.

It never rusts or tarnishes and is a great conductor, making it perfect for electronics.

The connections to these various devices are called buses, often rigid, overhead conductors that run along the entire substation.
