Introduction to Design of Distribution Overhead Power Line

Dear Readers the following blogs will be about designing distribution overhead power lines

So be with us to learn more have a good Read!!!

General

This blog describes the engineering process involved in designing distribution overhead power lines. These lines typically originate from Zone substations as Medium Voltage lines and are stepped down to Low Voltage through distribution transformers. Low Voltage overhead power lines then transmit power from transformers to customer installations. Some customers are supplied directly from the Medium Voltage network.

Overhead Power lines account for a significant proportion of  Power networks. These assets involve large amounts of capital expenditure, both by utility Power and customers. Also, these lines need to be properly designed and constructed and it is imperative that a high level of engineering input is put into their designs, particularly because these lines may be built in cyclonic areas. Effort expended here could avoid unnecessary expenses for utility Power and customers and ensure that the customer's requirements and all of utility Power's requirements are catered for.

Each overhead line requires different design considerations, configurations, layouts, etc. As such, there may be many different ways to approach a design.

The information contained in this blog will assist the designer to develop a structured design approach, and ensure that the optimum line configuration is selected at all times.
