The case for using high-voltage underground transmission cable systems continues to gain momentum. There are many benefits, including system safety and reliability; all with minimal impacts to the visual environment. Installing high-voltage underground transmission cable, however, can often pose unique engineering and installation challenges. A wrong decision during installation can pose significant safety risks, in addition to amplifying both project costs and future maintenance costs.


In this webinar we will discuss:
