allows electric power to be carried efficiently over long distances from electrical generation facilities to substations near urban areas. In the United States, most transmission lines use alternating current (AC) and operate at voltages between 50 and 765 kV. . (http://www.niehs.nih.gov/oc/factsheets/emf/epbasics.htm) Transmission lines end at transformer substations where the voltage is increased or decreased as required for further transmission. Transmission lines are made up of metallic conductors, each is designed to carry specific electrical voltages. The structures that support the conductors are made from single or double wooden poles, or lattice steel. A single circuit transmission line consists of a set of three metallic conductors to create a complete electrical circuit. A double circuit towers carry two sets of conductors. “The conductor must clear the ground at the low point between the towers by at least seven meters, height may vary according to different CSA standards. A lighting guard is or called sky wire is installed at the high point of the tower to avoid lighting outages.” (Fur, 2) . Then we have distribution lines which, utilities use that are lower-voltage to bring power from substations to businesses and homes. Distribution lines operate at voltages below 50 kV.

One of the major health issues that is being studied is cancer. Scientists as well as society are pondering if there is a link between electromagnetic fields and cancer? The electrical charges produce Electric and magnetic fields (EMFs). Devices that produce or use electrical power, like power lines and power transformers, give off EMFs. Common household appliances that use electricity give off EMF's such as like electric clocks, shavers, computers, televisions, and microwave ovens. Cancer I would say is the biggest concern that they are dealing with in this topic especially cance...
