The management team comprises by skilled engineers with at least 15 years of experience in design and manufacturing of switchboards. The cubicles are entirely manufactured in house by the use of modern facilities such as CNC punching machines, or the new electrostatic powder coating system. Assembly of the switchboards meet IEC and VDE standards and they are type tested by the VDE Germany, in conformity with IEC 60439-1 standards. The quality management system of ESIwas successfully certified in 2003 according to ISO 9001:2008 Customers can thus be assured that products from E.S International comply with international standards and of the highest quality.
