Basic Construction of underground cables

This article is the next and last part of Khuram’s article on underground MV/LV distribution systems. Enjoy and comment BELOW if you have any questions.

Underground electrical distribution is not only tidier but also less prone to environmental hazards as compared to the overhead distribution. Installation and maintenance cost, operational pros and cons, and a brief overview of cable structure are discussed in the previous part. Distribution transformers, switchgear and MV/LV cables are the main components of underground distribution system.

Structure and types of underground cables for a distribution system are discussed in this article.
