Underground High Voltage Systems Reduce Risks in Highly Inhabited Areas

High voltage systems play a major role transmission. These distribution networks can now be established in densely populated areas, vastly complex sites, and in rural areas either underground or underwater.

Underground transmission cabling solutions in Boston, MA are safer and healthier for the population than overhead high voltage cables because there is no contact with the current discharge. There are three ways to install high voltage cable systems. The first is buried underground where the insulators and conductors are not visible. There are fixed in either troughs or tunnels that are beneath the ground. With the trough method, the conductors are set tightly parallel to one another and enclosed in a concrete trough which is flush with the ground. The third way of installing underground high voltage networks is with the gas-insulated line method, where cables are confined in a rigid metallic tube filled with an insulating gas. The tube is then wrapped which almost nullifies the magnetic field.

Underground High Voltage Systems make transmission of high voltage power more reliable, safe, and convenient. This method is also more aesthetically pleasing, removing huge towers and unattractive power lines from visibility in highly crowded areas or in natural conservation areas. Underground cabling solutions reduce or eliminate audible noise and electromagnetic discharges.

Underground High Voltage Systems: Eliminating Hazards in Rural and Sensitive Locations - Wilmington, MA

Joseph Coupal - Friday, May 30, 2014

High Voltage cable systems serve a significant role in the scope of electricity transmission and distribution networks all over the world. Today, these systems can now be optimally installed in highly populated places or immensely sensitive environments, either underground or underwater.

Underground transmission cabling solutions in Wilmington, MA prevent the high-voltage cables from coming into contact with people or with other objects, while containing and controlling leakage current. High voltage underground cables can either be directly buried, gas-insulated, or placed in a trough or in tunnels. In direct-buried high voltage underground systems, conductors and insulators are buried below ground, showing no visible sign of the cables. Instead of being directly buried, high voltage cables are placed in a tunnel bored deep beneath the ground. Gas-insulated lines are a rather new technology that consist of tubular aluminum conductors which carry the current. The lines are then enclosed in an inflexible metallic tube filled with an insulating gas. This alternative is known for having a sheath that partially cancels magnetic field thereby reducing it. In trough, the conductors are placed closely paralleled to one another and contained in a concrete trough flush with the ground surface.

Underground High Voltage Systems have made it possible to reliably and conveniently transmit high-voltage power from production to consumption points all over the national grid. Replacing conventional overhead lines with underground systems wipes out the visual impact of large power lines. Underground transmission cabling solutions in Wilmington, MA also ensure that there are no audible noise and electromagnetic fields in particular areas.
