R & D
Research and development has always been PEI’s precedence. We think to new solutions, to new products, to new production processes and develop our infrastructures to implement our plans.
As main infrastructural development, in 2010 PEI launched a project to expand the area and renew, replace, upgrade the machines and production line equipments in a new site of 10,000 m2 including the workshops, stores, laboratory and administration buildings.

Benefitting from experienced staff we try to always be in tune with the state-of-the-art technology. We response to the extra-standard requirements of our customers, profiting our high-tech reference laboratory. Innovation is PEI’s life blood.
PEI’s VISION
is to be among five superior manufacturers of transformer solid insulating material.
PEI’s MISSION
is improving competitiveness characters to posses the regional and international markets.
