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.

An electrical insulation is a material that reduces or prevents the passage of electricity from one conductor to another due to its high level of electrical resistance. Let’s read Ginnie’s essay about electrical insulation failure.

The main purpose of insulation is to prevent any electrical shocks and reduce the possibility of any kind of electrical failures, making of is one of the most necessary aspects to take into account in the industry of electricity.

The reasons why insulation fails vary depending on the type of material and the element to be insulated. The following provides a description of the main reasons for insulation failure:

New article by an electrical engineer from Venezuela. Thank you to all the experts who participate in this community! Enjoy and  don’t forget to leave a comment if you  want to share your thoughts on the electrical contactor.

Nowadays, there is an increasing need for users to take control of the comfort and safety systems installed in their area (air conditioner, lightning, and others) [1]. There are powerful reasons for this, the main one is the birth of a new trend, that goes back to the year 1999 [2], known as Building Automation Systems (BAS). This is related to the need of having control over systems by adding a special panelboard, like a PLC, a relay, a control panel, among others.
