Industrial electrification

Expert partner for industrial electrification services

Ensuring uninterrupted and secure power supply is our area of expertise, and we understand that reliability is of paramount importance to industry. Whether construction or maintenance of electrical equipment is concerned, we reliably meet our customers’ needs with professional skill. We are an expert partner for industry in the design, construction and maintenance of distribution substations and power stations, among others.

Our industrial network services cover the design, construction and maintenance of the electricity distribution network and its power stations and distribution substations in the 0.4–400 kV voltage range. We build according to the customer’s ready-made designs or provide a turnkey delivery from licensing to the finishing touches. In addition, we provide leased electricity distribution products for maintenance downtime for the industrial sector.

Our electrical contracting services include

  • Construction of electrical equipment
  • Maintenance of electrical equipment
  • Measurement and testing services
  • Electrical engineering

Construction of electrical equipment

We offer electrical equipment construction services in the 0.4–400 kV voltage range as a turnkey contract, design and build contract or based on the customer’s existing plans.

  • 400 kV switchgear construction and renovation
  • construction and renovation of indoor and kiosk type transformer substations
  • construction of industrial LV and MV distribution network
  • construction and renovation of medium-voltage switchgears
  • construction and renovation of industrial switchboards
  • earthing network construction

Maintenance of electrical equipment

Our services include cleaning workof transformer substations and electrical equipment rooms, maintenance and testing of circuit breakers, renovation of transformer substations, medium-voltage switchgears and main distribution boards, as well as diverse troubleshooting and annual maintenance according to the maintenance programme. In addition, we provide our customers with “operation manager” service with maintenance contracts. If necessary, we can also carry out service and maintenance work without interruptions.

Measurement and testing services

Our services include measurement and testing services, such as earthing measurements, partial discharge and loss factor measurements, commissioning measurements, testing and troubleshooting (in the 0.4–20 kV voltage range) and thermal imaging.

Partial discharge and loss factor measurements provide valuable information about the condition of cable lines. Failure of cable lines and their extensions and terminals can be caused by overloading, manufacturing or installation errors, environmental stress or ageing. To detect these faults, we offer partial discharge measurements as an online measurement service as well as partial discharge and loss factor measurements of medium-voltage cable lines as an offline measurement service. Comprehensive commissioning measurements provide assurance of cable integrity and enable condition monitoring. With regular maintenance measurements, it is possible to monitor the condition of the cable and prevent failures before they cause financial or production problems.

Electrical engineering

We carry out electrical engineering for projects of different sizes with the scope of delivery desired by the customer. We can start the engineering assignment from the need assessment and complete it all the way to the final documentation. With strong experience and modern design tools, we support the project from start to finish. In addition to electricity network companies and contractors, our customers include industrial companies, ports and the public sector.

Our electrical engineering services include: 

  • Distribution grid (0.4–20 kV) engineering
  • Switchgear engineering
  • Substation engineering
  • Transformer substation engineering
  • Power line (110–400 kV) engineering

Leased electricity distribution products

We provide distribution transformers and power containers as leasing products. We implement temporary electrification and supply backup power units, e.g. for construction sites, major events as well as maintenance downtime periods for the industrial sector.

Industrial construction services

We offer industrial construction services as comprehensive turnkey deliveries. Thanks to our international networks and versatile expertise, we implement projects of different sizes all over Finland with high quality and based on the customer’s needs.

Turnkey contracting of energy infrastructure

We provide electrical services for the entire life cycle from preliminary studies and design to construction, maintenance and, if necessary, follow-up inspections.

Industrial traffic and lighting solutions

We offer intelligent transport solutions, such as traffic lights and cal traffic signalling systems, as well as electric charging stations for industrial areas. We also carry out construction and renovation of area lighting.

Sinimäki substation responding to increasing electricity consumption

We built the new Sinimäki substation in Nuijala, Espoo, which is responding to the increasing need for electricity in the area. The substation will also support the strategy of the carbon-neutral City of Espoo and its pioneering role in clean energy solutions. The new substation will replace the current Nuijala substation. Caruna Espoo Oy ordered the work, and we implemented it as a turnkey construction contract.
