Diferencial – Electrotécnica Geral Lda, established in 1981, was born owing to an increasing request of the market, for the development of “turnkey” solutions, suitable to the customer needs, in the following areas:

• Medium and Low Voltage infrastructures.
• Production of electrical distribution and control boards
• Electrical material distribution and technical support

Due to inevitable growth and diversification of services and products, in 1991, we felt the need of building our own plant, which allowed us to answer those requests with more efficiency.
We today count on about 2.500m2 of covered area.

Our presence in the market is seen by our customers as a symbol of quality and guarantee that the work is executed successfully and honestly.

Given demands of our customers, our own needs and meet changing market, we began a reorganization of the company that came to end with the Quality Certification according ISO 9001:2000 in September 2003. In August 2009 the certification of Quality Management System has been renewed in accordance with the requirements of EN ISO 9001:2008.

Our goal is to provide our customers with performances, more comfort and confidence through our collaborators and commercial / technological partnerships.

New technologies, such as telecommunications, structured networks for voice and data, security systems, combined with the facilities of medium and low voltage are currently our main activities.

Over three decades we maintain partnerships worldwide renown, whose products honor us are one of the reasons for our success
