History

Eltra GmbH

1989

Eltra Elektromaschinen- und Transformatorenbau GmbH founded by Bernd Engel, Robert Weinand, Andreas Filz and Bruno Zender.

1994

A new production hall with an area of more than 1000 m² and an additional administration building were constructed.

1996

Quality management system according to EN ISO 9001 was implemented and certified by DQS Frankfurt, valid until 2002. Up from that year, all of the processes are carried out in conformity with the corresponding directives.

1999

Production capacities were enlarged by a supplementary hall with more than 1000 m². An assembly line with encapsulation system was introduced, in order to produce completely encapsulated transformers (isolating safety transformers) for illumination technology. Furthermore, a strip winding machine was purchased, so that aluminum and copper windings for coils and chokes could be manufactured as well.

2001

Production of starting and isolating transformers according to the requirements of classification societies for naval construction, e.g. (Klassifikationsgesellschaften auflisten), and their inspections carried out on site.

  • Bureau Veritas (BV), Frankreich
  • Det Norske Veritas, (DNV), Norwegen
  • Germanischer Lloyd (GL), Deutschland
  • Lloyd-s Register of Shipping (LRS), England
  • American Bureau of Shipping (ABS), Amerika
  • China Classification Society (CCS), China
  • Registro Italiano Navale (RINA), Italien

und deren einschlägigen Prüfungen vor Ort.

2002

Adaptation of the software to Windows basis, development of new software tools for construction and sales departments

2003

Introduction of a proper UL isolating system and type related UL admissions for transformers and chokes.

2008

Production area meanwhile has reached 3000 m². A second strip winding machine was installed, and the in-house mechanical department was complemented by a new lathe and bending technology for metals.

2010

Our product portfolio was enlarged by :

  • High voltage air-core transformers for water treatment, ozone and foil coating plants
  • High voltage isolating transformers
  • Special transformers for research applications

2012

A third strip winding machine was set into operation, in order to achieve increased width for wrapping foil.

2013

A new impregnating machine and another drying stove were installed.

2014

3D CAD construction software was implemented in the system.

2015

Further update of the in-house software for purchase and sales departments.

2016

New archiving software to speed up management procedures and document handling.
