Telecom cables are made of metal or optical fibre. Sampsistemi produces machinery and equipment for metal telecom cables, which in turn may be subdivided into the categories of coaxial cables or multi-pair cables. The type of cable applied depends on the frequency of usage. Multi-pair cables have become increasingly popular in recent years, since they can transmit both data and vocal signals. LAN cables are a typical example of multi-pair cables. These are flexible cords and have gradually replaced expensive co-axial cables, which were previously used for networking in buildings. The growing use of copper multi-pair cables has also given a new lease of life to copper distribution cables, slowing a tendency to substitute these with optical fibre cables.
Metal telecom multi-pair cables are produced using tandemised sheathing and intermediate drawing lines with preheaters. These lines combine drawing and extrusion technology in a single solution, exploiting the technical synergies available at Sampsistemi and enabling customers to benefit from working with a single supplier that develops and produces the whole line in-house. The extrusion of physically expanded materials (obtained by nitrogen injection) increases the speed of signal transmission, and similar technology is also applied to sheathing with polyethylene and fluoropolymers. When it comes to fluoropolymers, users not only reap great technological benefits, but they also save in terms of polymer costs.
Having undergone remarkable growth over the last two decades, the telecom sector has slowed in recent times, but the technological complexity of this product remains a barrier for unqualified suppliers.
