We design, test and manufacture our solutions and products. This gives us an opportunity to serve customer needs on an individual level and bring new innovations to the market.

Our in-house R&D in 5 countries enables us to respond quickly to our customers' demands, make modifications to products and bring them fast to market. Our highly skilled experts have extensive experience especially in the product development of LV and MV networks. 

 

 

We Test

We test our products beyond industry standards, giving customers safer products faster to market – something many others can't offer.

Extensive testing secures that the products are durable, high-quality and long-lasting. In addition to reliability and high quality, own testing ensures a faster product development cycle to get our products to market more quickly. 

Ensto Laboratory in Porvoo, Finland.

Line and Cable Accessories

In Porvoo, Finland, we have our own ILAC-accredited in-house laboratory (EN ISO/IEC 17025), where we test our underground cable accessories. The tests include aging, short-circuit, tensile, high-voltage, PD measurements, climate, corrosion, and impact.

Other line accessory products also go through various tests during their manufacturing process to ensure that their are of high quality before delivered to customers.

Testing in Villefrance.

Distribution Automation

Our distribution automation products are manufactured and tested in Villefranche-sur-Saône and Bagnères de Bigorre, France. The testing of the products includes a range of advanced methodologies to ensure product performance and reliability throughout the lifecycle.

Key tests include hardware-in-the-loop simulations to replicate real-world conditions, such as advanced grid fault scenarios; custom test benches for functional, communication, security, and system-level evaluations; and automated regression tests to maintain stability and prevent performance degradation.

These tests, supported by fully automated test benches integrated into the product development process, enable continuous validation from development to production, ensuring durability and compliance with identified risks and quality standards.

Secondary substations in Vaasa.

Substations

Our substations are made and tested at Ensto Maviko's factory in Vaasa, Finland, before they are delivered to the customer. In primary substation projects, commissioning testing is done on-site.

In addition, we have comprehensive testing services for both primary substations and smart compact secondary substations. We also have experience in testing protection relays, and our expertise covers all the most common protection relays.

We Manufacture

Ensto's factory in Keila, Estonia.

We have world-class manufacturing in 9 specialized factories in 6 countries. We strive for superior quality, excellent delivery capability, efficiency, and high quality standards in everything we do.

Efficient and well organized Operations are essential for us at Ensto to exceed our customers' expectations. It is not enough to improve things once. Improvement in business needs to be seen as a continuous effort.

Towards World-class Manufacturing

Ensto Operational Excellence (EOX) program was launched back in 2010 to strive Ensto Operations towards world-class manufacturing with the set of selected Lean Management initiatives. The journey has not ended: we have defined world-class manufacturing at Ensto as continuous improvement in quality, efficiency, delivery capability and flexibility.

One of the most important aspect of the EOX is the empowerment and involvement of our people. Respect and building people are at the heart of EOX. Every person working on all levels of the organization are contributing and giving their valuable input for the EOX on daily basis and working towards the world-class manufacturing.

LEAN-initiatives Supporting Us

At most of our factories, we use a selected set of LEAN-initiatives which support us on our journey towards world-class manufacturing: 

  • 5S: A method for organizing workplaces, a base for continuous improvement and our "visiting card"
  • War Room: A core method for continuous improvement
  • Andon: A signalization method for an immediate response regarding process or quality issues
  • Ensto Equipment Effectiveness: A method for improving the effective use of machines; shortening setup times, decreasing cycle times, and eliminating machine downtimes.
  • Preventive Maintenance: A method for reducing machine failures
  • PULL: The basic steering method for the main material flows. Replenishments are made against a real demand from the downstream.
