electrical and insulating
technologies division

Operating since 2000, our division studies and applies the properties of minerals in the field of high-tech insulation. The ambition is to create innovative and non-standard products, complex shapes made to design or sample, and unique details. All this is made possible thanks to our internal laboratory, equipped with the most advanced instruments of investigation and experimentation,
in collaboration with the most established professionals in the sector and important Italian, European and American research centres (University of Genoa Department of Electrical Engineering, CNR-ISTEC in Faenza, Mersen research centre in Lyon).
The production chain is organized to ensure quality control, to allow complete traceability of materials and components, and to keep the archive (paper-mechanographic) of what has been realized updated.


We are considered a reference point for the production of ceramic and composite products. We develop materials that are resistant to arc, high temperature, thermal shock, vibration; new materials that comply with the strict regulations of the various sectors of use.
made with economic, ecological, time-saving industrial processes.

The main applications:

  • trains and subways: arc extinguishing chambers for medium and high voltage with very low arc wear
  • shipbuilding industry: large-sized insulating panels
  • aerospace industry: highly reliable insulation parts
  • steel industry: thermal insulation for high temperatures and heavy-duty applications
  • industry: ceramic insulators and extinguishing chambers for high voltage operation

Our in-house laboratory is engaged in continuous research and development. The collaboration with Universities and specialized Research Centres is decisive. The Department of Electrical Engineering of the University of Genoa has contributed to the development of arc resistance tests, applied voltage between plugs and dielectric strength tests. It has also been involved in the design of equipment for the control of the electrical characteristics of materials, in compliance with international standards.
The CNR-Istec of Faenza has collaborated in the structural, mechanical, physical and chemical definition of our most innovative products such as ceramic composites.


The innovative, eco-friendly, ductile ceramic composite for high power.

Refrarc p328 is flame retardant, based on a non-hydraulic bond consisting of refractory alumina and silicon oxide with particles joined by covalent bonding. The moderate heat treatment necessary to stabilise the bond prevents the propagation of vapours at high power.
Particularly versatile, it expands our range of unique plate technology for high power applications.
refrarc p 328 is the revolution in innovative refractory materials.
Those are the plusses:

  • minimal porosity
  • high mechanical strength
  • excellent thermal shock resistance
  • development of complex shapes
  • respect for the environment
  • no radioactive residue
