Finland, a global leader in sustainability and technological innovation, is currently undergoing a massive transformation in its industrial and energy landscape. As the nation strives to reach carbon neutrality by 2035, the demand for high-efficiency electrical distribution systems has skyrocketed. Overmolded busbars have emerged as a critical component in this transition, providing the necessary insulation, safety, and space-efficiency required for modern Finnish engineering projects.
From the bustling tech hubs in Helsinki and Espoo to the heavy industrial zones in Tampere and the maritime shipyards of Turku, Finnish companies are integrating overmolded busbar technology to enhance the reliability of their power systems. The unique Finnish climate, characterized by extreme temperature fluctuations and coastal humidity, demands components that offer superior environmental protection. Overmolding provides a seamless, airtight seal that protects copper or aluminum conductors from oxidation and moisture, making them ideal for the harsh Nordic environment.
With Finland's rapid expansion of wind and solar power, large-scale battery energy storage systems are vital. Our busbars ensure minimal power loss and high thermal management efficiency.
Finland is a pioneer in electric ferries and icebreakers. Overmolded busbars provide the vibration resistance and compact footprint necessary for maritime propulsion systems.
As a hub for global data centers, Finland requires power distribution that generates less heat. Overmolded designs allow for optimized airflow and higher power density.
With 2700 employees, 4 factories, and over 200 R&D engineers, Sanco is a national high-tech enterprise dedicated to becoming a leader in connectivity technologies. We specialize in the R&D and manufacturing of electrical connection systems for automotive, rail transit, industrial, and energy storage applications.
For our Finnish clients, we provide tailored solutions that meet strict European safety standards and the specific technical requirements of the Nordic market. Our expertise includes high-voltage connectors, MSDs, laminated busbars, and injection-molded busbars designed for durability and performance.


The transition to Industry 4.0 in Finland requires components that are not only efficient but also intelligent and robust. Overmolded busbars offer several advantages over traditional cable-based systems or heat-shrink insulated busbars:

In northern Finland (Lapland), electric vehicles face the challenge of extreme cold, which can affect battery efficiency and material flexibility. Sanco's overmolded busbars use specialized PA66 or PBT plastics that maintain their structural integrity and dielectric strength even at -40°C. This ensures that EVs in Oulu or Rovaniemi remain safe and functional throughout the long winter.
Finland's maritime industry is rapidly shifting toward hybrid and fully electric propulsion. The saline environment of the Baltic Sea is highly corrosive. Our overmolded busbars offer a hermetic seal that prevents saltwater ingress, protecting the copper core from galvanic corrosion. This is crucial for the longevity of battery racks installed in passenger ferries operating between Helsinki and Tallinn.
The "Smart Helsinki" initiative involves integrating IoT sensors and high-speed communication into city infrastructure. Overmolded busbars are used in compact power distribution units for smart street lighting and 5G small cells, providing a clutter-free and safe power solution that withstands the urban environment.
As we look toward 2030, several trends are shaping the future of busbar manufacturing, particularly for the Finnish and European markets:
