Industrial electrification

Construction of electrical installation

We offer electrical installation 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
• process and industrial electrification
• area lighting
• earthing network construction

Construction of distribution networks

We offer low voltage (LV) and medium voltage (MV) distribution network construction services comprehensively and with extensive experience.

Our expertise includes

• MV cabling
• LV cabling
• overhead transmission line construction
• transformer substation work
• installations and replacements of transformer substations
• distribution cabinets
• condition inspections
• renovation of distribution networks

Electrical maintenance services

We provide various electrical maintenance services. If necessary, we can also carry out service and maintenance work without interruptions.

Our electrical maintenance services include

• cleaning work of transformer substations and electrical equipment rooms
• maintenance of circuit breakers
• renovation of transformer substations, medium-voltage switchgears and main distribution boards
• operation and maintenance work according to maintenance contracts
• maintenance of medium-voltage cable lines
• fault detection, fault location
• cable fault location
• condition inspections

Measurement and testing services

Our services also include measurement and testing services, which include

• commissioning measurements
• continuity measurements
• sheath integrity measurements
• earthing measurements
• partial discharge measurements
• loss factor measurements
• power quality measurements
• voltage tests (MWT)
• settings, configurations and testing of circuit breakers and relays

Partial discharge and loss factor measurements (PD and TD measurements)

With our measuring equipment, we can perform commissioning and maintenance measurements of cable lines as both online and offline measurement services. We can also conduct VLF (Full MWT) voltage tests in accordance with requirements

• for wind farms
• for solar parks
• for distribution networks
• for substations
• for industrial sites

Partial discharge (PD) and loss factor measurements (tanDelta) ensure the integrity of the entire cable line and enable its condition monitoring. With regular maintenance measurements, it is possible to monitor the condition of the cable line 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.
