power transport capacity and reduced losses, which requires innovation in new or improved materials. “Another big market driver is sustainability, which, in turn often involves economic considerations as well. “The goal is to make terrestrial and submarine cables with increasingly fewer metals, as well as make them recyclable.” Cable changes Prysmian Group’s BU Multimedia Solutions now offers its range of E-Series central tube cables with increased tensile strength in compact designs. The company has also upgraded the pulling strength of its metallic armored central tube designs in the E-Series from 1,000N to 3,000N, and for the non-metallic cable types from 1,500N to 3,000N. Central tube cables with 24 fibers have traditionally needed a larger diameter than smaller fiber counts. Prysmian now offers the same tube diameter for two to 24 fibers, giving a reduced diameter for higher fiber counts. “With upgraded central tube cables our customers receive outstanding quality in compact designs at a reasonable price, hence greater savings on investments — especially [as] the installation of fiber optic

for the Greek Evia, Andros and Tinos islands’ interconnections.

Prysmian developed, supplied and installed the first cable with armor made from a composite material based on high modulus synthetic fibers. Water installation, performed by Prysmian’s Cable Enterprise , reached 550m in the link between the islands Evia and Andros. The synthetic armor can be 30 percent lighter than steel, and allows installations down to 3,000m. The same technology will be used in 2020 for the Crete-Peloponnese submarine interconnection project, which requires an installation depth of about 1,000m. Installation risks will be minimized, compared with using metallic armored cables. “This product is the outcome of seven years of [research and development] activities, including modeling, materials selection and cable testing,” explained Srinivas Siripurapu, EVP and chief R&D officer, Prysmian Group. Stefano Franchi Bononi, R&D projects director in Milan, Italy said in an article: “Market drivers for submarine cables mean a move to lighter weight, higher Increased depth makes more routes available for subsea cables.
