We are an international technology company and a family business, which enables green transition, reliable and safe supply of electricity by creating sustainable solutions for electricity distribution.  Our target is to help our customers to build and improve their distribution networks and meet the surrounding challenges. Global warming, growing urbanization, extreme weather conditions, and increased electrification demand smarter and more resilient electrical infrastructures. Our innovative solutions adapt to these challenges, providing sustainable, long-term answers.

Over voltage protection is needed e.g. for electricity distribution and supply, consumer in house supplies and distribution transformers due to lightning strokes and switching actions. The
most effective means of protection is the use of surge arresters in the vicinity of electricity equipment.

Ensto provides a wide range of high voltage surge arresters for more than 25 years, based on long
experience in the field. In particular, they have been proven to operate reliably even in the harshest environmental conditions.
