With significant expertise, a steadfast dedication to safety, professional competence, and the highest quality standards, Nepcon in an industry leader in substation design, construction, and maintenance in Pakistan. From foundations to fully commissioned substations, Nepcon offer mechanical and electrical installation services. The capability and competence to complete the associated substation infrastructure works and provide full turnkey solutions for our clients on a regular basis.
Types of Electrical Substations:
Most construction experts consider electrical substations to be difficult undertakings. Civil works in electrical substations include the construction of many buildings/components that are divided into parallel and overlapped implementation stages that need a range of resources, are often fairly expensive, and take a long time to complete. The civil engineering includes a lot of details and information for the structural drawings that are needed to design switchgear installations. The structural drawings serve as the basis for constructing structural design plans (foundation, shell and reinforcement plans, equipment plans).
A transmission substation serves as a hub for multiple transmission lines. A distribution substation serves as a link between the transmission substation and the power consumer, decreasing transmission voltage to a level suitable for distribution to houses, buildings and apartments.
The collector substation, which is commonly used in hydroelectric power plants and wind farms, the switching substation, which is typically built next to a power station to connect and disconnect transmission lines, and the converter substation, which can adjust the frequency of transmission currents, are all examples of substations.
Selecting a Site:
When building a substation, proper site selection is critical. You must consider a variety of criteria when scouting a site, including site accessibility, drainage and erosion protection, and the amount of site preparation required. To avoid injury, the facility should also be out of the way of the public, yet still somewhat centrally situated within its service area.
Design:
Choose engineering designers to make a detailed blueprint for the substation. Engineers frequently visit a site and then go over the soil reports thoroughly. Circuit breakers, high voltage and low voltage switches, surge arresters, insulated cables and raceways, and AC/DC station power and control system supplies are all part of the substation design.
Areas of expertise and services:
- High- and medium-voltage substations construction
- Implementation of substation construction component tasks, including design, architectural construction, electrical technological installation, and commissioning
- Reconstruction, substation extension, and primary and secondary device replacement
- Power plant electrical equipment design, construction, and commissioning
- Substation and power plant maintenance and troubleshooting
- Diagnostic evaluations (transformers, primary devices, protection and control engineering equipment etc.)
