In particular is described an industrial process for the production of conductors in copper and/or aluminium having a rectangular section (strips) coated with graphene, in order to increase thermal and electrical conductivity of said conductors, which are then used in all the windings for power transformers.

Wires, strands, rigid and flexible ropes having high electric, physico-chemical and environmental performances

Here described is the production of wires, strands, rigid ropes and flexible ropes having high electric, physico-chemical and environmental performances for the purposes of electrical conduction, enhanced through multilayer deposition containing graphene, and a method for their preparation. Each single wire, strand, rope and/or cable according to the present invention is produced through electrochemical deposition processes and/or of a different nature, in order to potentiate electric, physico-chemical and environmental performances (in particular electric conductivity) and the resistance to the thermal and corrosive actions of said wire, strand, rope and/or cable, facilitating furthermore subsequent manufacturing processes and making the connection of cable terminals and/or anchors less critical. Said wire, strand, rope and/or cable obtained at the end of the manufacturing process can be used bare for the purposes of electrical conduction or constitute the core of insulated cables to be used in the automotive and energy sectors.

Composite material for lightening various structures

A method for preparing a composite material comprising a felt made of fibers is here described. Such composite material is aimed at manufacturing light, strong and low cost structures, to be used in the automobile, rail and naval transport and in general for all those industrial applications where light and very resistant structures are required.

Tank made of composite material

A tank (for example a compacting container) made with a composite material, having as main characteristics a high lightness and resistance. Lightening (reduction of weight) of the structure of the tanks used in the field of urban waste collection, has different advantages, such as for example: minor fuel consumption (and therefore minor environmental pollution) by vehicles involved in the collection of urban waste; and the possibility to increase the quantity of transportable waste, without having to further burden the structure of the vehicles.
