323 ACR
Informazioni sul progetto
The 302 and 323 transmission lines, both 345,000 kilovolts, were first built in 1968 to connect the Carpenter Hill and Medway substations. Part of this line is now called the 323 line. The section owned by National Grid runs about 14.4 miles, from the Millbury #3 substation to the Milford/Medway town line.
Today, the 323 line includes 153 wooden poles and 14 steel poles. The steel poles show signs of aging, including light rust and wear near their bases. The wooden poles are in worse condition and have problems such as rot, cracking, bending, and damage from woodpeckers. Almost every wooden pole has some level of damage.
This project will upgrade the transmission line by replacing all existing wooden poles with new steel poles designed to last longer. Crews will also install new fiber-optic ground wires and replace insulators and other equipment. These improvements will help make the electric system safer, more reliable, and better prepared for the future.
Benefici del progetto
This project improves the transmission line by replacing worn out wooden poles and an aging shield wire. The upgrades will help provide safe and dependable electric service to customers and strengthen the local transmission system. The improvements will also extend the life of the line, helping it serve the community for many years to come.

Fasi di costruzione
-
Cosa aspettarsi
Electric Transmission improvements take place in several phases. The descriptions below show common construction steps, but the exact process and materials may vary.
-
Preparazione del sito
Il primo passo consiste nella rimozione di alberi e sterpaglie. Questo lavoro permette alle squadre di costruzione di realizzare in sicurezza le strade di accesso e di eliminare gli alberi che potrebbero cadere sulle linee elettriche.
-
Controlli ambientali
In seguito, si prendono provvedimenti per proteggere l'area durante i lavori di costruzione. Questi possono includere tappeti, barriere di contenimento del limo e contenitori per i materiali edili.
-
Ricostruzione della linea di trasmissione
Crews use heavy equipment, including cranes. New foundations and structures are installed, along with fiber-optic cables and new wires. Lastly, old structures are removed, and the lines are powered.
-
Restauro
After construction, crews restore the work area and return the ground as close as possible to its original condition, unless otherwise specified by regulatory requirements or agreement with a landowner.
