OTTOTECNICA has been for over 50 years protagonist in the domestic market
in the electro-mechanical and electronic field of the electrical safety.
Who we are
Ottotecnica for over 50 years has been designing and manufacturing devices and instruments for the protecion from the electrical risk in the:
electric distribution LV-MV-HV | railway traction | subway, tramway, trolley-bus way traction
for almost twenty years Ottotecnica has been working in the redaction of the national and international CEI and IEC-TC 78 standards concerning the earthing and short circuit devices, insulating tubes and voltage detectors.

Quality of the materials
When the first aim is the safety, there is no room for compromises. The constant attention and check on the features of the raw materials and on the working processes become a real plus for their daily use in terms of reliability and duration in time, in every situation. Every product can thus offer an affective value, fully complying with the customer’s expectations.

Research & development
The passion for the innovation and the optimization allowed us a constant state of the art attitude. Either in the mechanics or in the electronics we’ve been able to introduce solutions even where it seemed to be impossible, thanks to the studies done by an inner team dedicated to the design. Our participation in the redaction of the national CEI norms and standards and IEC international is an evidence of this skill.

Experience & specialization
The safety devices requires the examination of different technical aspects such as mechanical, electric and even ergonomic and operative aspects that are peculiar for each device. This requires a special skill and knowledge that can be acquired only after years of expertise and constant comparison with the different needs. The high level of peculiarity in the use of each device makes it incomparable to other similar solutions and allows the offer of unique technical features (insulations, short circuit currents).

Adaptability versatility
The high number of the potential applications related to the electric safety requires a particular attention to the different needs. Our constant concern and availability to a dialogue with the ones who use the devices, through the examination of the needs, the recommendation and the common search for the best possible solution. We can even find eventually variations if it’s needed, in order to upgrade a product according to a specific use and to get the necessary electric and functional features needed

1957
Ottotecnica is born as a foundry of non-ferrous materials, its name means brass technique (from Italian: ottone=brass; tecnica=technique).
1967
Alongside Enel, born in the 1962, Ottotecnica begins the design and manufacture of earthing and short circuit devices as well as the press-forging and production of sectioning and shunt terminal boards made of brass on insulating steatite supports.
1977
Ottotecnica continues to develop the know-how in the electrical protection. In the same years, always side by side with Enel and then with Ferrovie, begins the production of press-forged fiberglass articles.
1987
In parallel with the development of the devices for electric safety, the R&D staff of Ottotecnica focuses with profit on the creation of innovative energy-saving systems in the public lighting, cathodic protection of underground metallic structures and systems for the voltmetrical protection in the electrical traction; systems to be placed in the previously developed fiberglass containers.
1997
Ottotecnica achieves relevant results in the electronic sector with the development, in addition to the electronic capacitive unipolar voltage detectors, also of amperometric clamps with open toroid, phase comparators with aerial radiofrequency and for insulated switchgears with sulfur hexafluoride.
2007
Between late 90s and early 2000s, Ottotecnica contributes significantly with Enel to complete the unification of the MV LV EA0320 tables: a new way of conceiving the earthing and short circuiting through the use of the “4th clamp” and the “concomitant voltage detection”.
2017
In recent years there has been a strong commitment to R&D, leading to the emergence of several innovative products targeted at the global market. In the electric distribution area, Ottotecnica focuses on High Voltage designing and manufacturing the electric field voltage detectors and the new earthing and short circuit lance devices for HV substations. In the electric traction area, other new products are introduced, such as the meter for the height and geometry and residual thickness of the catenary-contact lines and the innovative earthing and short circuit device for electric traction with foldable jaw and torque tightening.
