Authorized Contractor of the Electricity Distribution Company

Before electrical energy is used by consumers, it is prepared for delivery by the electricity distribution company at various voltage levels. To carry out its infrastructure projects, the distribution company works with contractors who, after obtaining the necessary certifications and completing relevant training, are authorized to implement distribution networks under the company’s supervision. Nirooafza Electrical Engineering is one of the trusted contractors of the distribution company, involved in various power delivery projects at the distribution level. The company is authorized to operate on 20kV and 400V voltage levels.

20kV Overhead and Underground Substation

The first and most critical component in an electrical distribution system is the transformer, which converts between different voltage levels. The installation location of a transformer can vary depending on site conditions, size, and capacity. Overhead transformers are mounted on medium-voltage utility poles, while ground-mounted transformers are installed and operated on the ground within built-in or compact substations.

Low-voltage and medium-voltage utility poles

To carry transmission and distribution conductors over long and short distances, utility poles of various sizes and materials are used.
These poles can be made of concrete, metal, or wood, depending on the application and environmental conditions.

Standard Electrical Panels Approved by the Distribution Company

The load distribution centers within the electricity distribution network are various types of electrical panels installed and operated at different points across the grid. These panels come in different types — from distribution panels mounted below transformers, to feeder and shelter panels used for underground power distribution, and finally metering panels that measure the energy consumption of end users.
