Electrical Contracting Services

Electrical contracting services cover the installation, field implementation, testing and commissioning processes of energy infrastructure in businesses of different scales, from industrial facilities to commercial buildings. This service should not be considered only as assembly work. A correctly planned electrical contracting process ensures that the system becomes safe, orderly, efficient and suitable for operation. For related context, see Transformer Substation Design.

Correct installation of electrical infrastructure in factories, production facilities, warehouses, shopping centers, hospitals, hotels, business centers and similar buildings is critical for both operational continuity and occupational safety. Mistakes made in electrical contracting applications can lead to problems such as energy interruptions, equipment failures, inefficient operation and high revision costs in the future. For related context, see Electrical Installation Periodic Inspection and Conformity Report.

As Pow-Sys Güç Sistemleri, we handle site survey, needs analysis, load assessment, implementation plan, field assembly, testing and commissioning steps with an integrated approach in electrical contracting projects. During the technical preparation stage before the project, we contribute to establishing the system on the right foundations with LV/MV/HV project design and consultancy service. For related context, see MV Project Approval and Medium Voltage Design Service.

Within the scope of electrical contracting service, power distribution panels, power factor correction panels, MCC panels, control systems, field feeder lines, lighting and socket installations, cable trays, busbar infrastructures, grounding applications and auxiliary power systems can be included in the project. The installed infrastructure can also be supported, when required, by electrical installation periodic inspection and technical inspection processes. For related context, see Short-Circuit Analysis and Relay Selectivity Studies Service.

In a successful electrical contracting application, not only material selection but also the engineering approach is decisive. Cable cross-sections must be determined correctly, panel locations must be planned in an orderly way, protection equipment must be selected appropriately and the system must be planned to allow future expansion. Especially in production facilities, this planning directly affects operational efficiency.

Electrical revision and expansion projects carried out in operating facilities require separate expertise. Because when the existing system cannot be completely stopped, power interruptions must be planned in a controlled way, critical loads must be identified and the transition process must be managed carefully. Therefore, electrical contracting service means not only installation but also proper field organization.

In some projects, the implementation scope does not remain only on the LV side; MV switchgear, transformer connections, power supply infrastructure and protection systems may also be included in the process. For such needs, we can plan our services in an integrated manner with high-voltage maintenance and testing, high-voltage operation responsibility, transformer operation responsibility and transformer services.

The quality of field workmanship in electrical contracting projects plays a major role in the long service life of the system. Orderly panel internal wiring, proper planning of cable routes, complete labelling and correct implementation of connection points both facilitate maintenance and shorten fault intervention time.

After installation is completed, the testing and measurement stage must be carried out completely. Energizing the system before insulation checks, phase sequence verification, grounding continuity, protection equipment function tests and panel checks are completed can create serious risks. Therefore, technical verification before commissioning is an indispensable part of the electrical contracting process.

Correct operation of protection systems is another subject that should not be neglected in electrical contracting projects. Especially when selectivity and tripping coordination are not designed correctly, a small fault can affect a wider area. At this point, relay and selectivity studies provide a significant advantage for system safety.

When receiving electrical contracting service, future needs must also be taken into account. Businesses may invest in new machines, increase production capacity or make changes in field layout over time. Therefore, reserve capacity, spare outgoing feeders, additional panel areas and infrastructure solutions suitable for expansion should be considered during the initial installation phase.

In some facilities, energy infrastructure must be evaluated together with generators, UPS systems, fire systems and lightning protection solutions. In this case, subjects such as generator inspection services, fire systems periodic inspection and lightning protection periodic inspection can also be included in the overall planning.

Grounding infrastructure is one of the most important safety subjects in electrical contracting applications. An unsuitable or insufficiently designed grounding system can create serious risks for both equipment safety and human health. Therefore, grounding inspection should be considered during system design and verification.

As Pow-Sys Güç Sistemleri, we provide electrical contracting services with an engineering perspective, orderly field implementation, technical inspection, a testing-measurement approach and a solution model shaped according to the need. Our goal is to create an electrical infrastructure for your business that is not only operational, but also safe, sustainable and manageable.

If you would like to receive detailed information about electrical contracting service, request a site survey for your new investment or revision project, or create a technical proposal specific to your business, you can contact us. We can determine the scope suitable for your needs and plan the project with the most appropriate method for the site.
