We are dedicated to the use of non-toxic insulation materials that are halogen free, have lower gas emission and smoke opacity and prevent flame spreading in case of fire.
2. The production process continues with the primary insulation and stranding phase of the semi-finished product. This semi-finished product builds the base for further stages of our production.
3. In the following steps, through the most modern equipment, shielding and taping operations are carried out (mainly dedicated to special cables).
4. The last production cycle involves the secondary insulation phase or the final coating in insulating material of the product obtained with a sheath in specific plastic materials according to the type of cable under production.
All production steps involve the use of innovative techniques for process control, in order to ensure compliance with the different types of cables. The production range covers many sectors, from railways, optical, telecommunications, oil&gas, industrial automation to marine industry, as result of continuous investments in research and development.
The production process is completed by a state-of-the-art laboratory for tests and inspections, which allows us to continuously monitor the compliance of the products with the technical and regulatory specifications. The laboratory is operated by highly skilled technicians, has the latest test equipment and performs 100% of the characterization on raw materials and normative tests on the finished products.
Our products have been designed and engineered in Italy, and our Chinese production reflects and improves on that know-how.
Metallurgica Bresciana S.p.A.vwas founded in 1968 starting with the production of copper multi-tubes for instrumentation in the Oil & Gas sector.
In the early 90's, Metallurgica Bresciana see the broadband business opportunity and decide to invest in the newest machinery for the production of fiber optic cables.
In 1993, as a result of a large investment, the construction of the first and only linear electron beam accelerator in Italy became a fact. E-beam irradiation is a process in which the polymer is exposed to a high charge stream of electrons which improves the mechanical and physical properties of the insulating material. This helped with the development of cables for the railway sector, such as internal cabling for rolling stock and miniaturized high temperature resistant cables for railway and industrial applications.
In 2011 Metallurgica Bresciana S.p.A. expand its international activities by establishing a new production site in Ma'anshan, China for the production of cables for the local market.
The quality of cables we are making are the key factor for the safety of mass transportation. We are dedicated to the satisfaction and success of every customer.
