Publication number: 20200183114Abstract: Disclosed is an optical cable that includes an outer sheath housing a number of optical fibers, wherein the outer sheath has an outer cross-section in the shape of a hexagon. The outer sheath then exhibits six flat surfaces longitudinally extending along the whole cable length. Any one of such flat surfaces may be covered with a thin layer of glue and then be attached to the wall surface. As this surface is flat, a reliable and durable fixing of the cable may be achieved using an amount of glue which is far reduced in comparison to the amounts of glue typically required for fixing known cables having a round cross-section.Type: ApplicationFiled: December 11, 2019Publication date: June 11, 2020Inventors: Gerard PERA GOLZALVEZ, Fabio ABBIATI, Davide CESCHIAT, Nayane LAZZARIN, Mauro MARITANO

Patent number: 9595367Abstract: A high voltage direct current cable includes at least one electrical conductor, at least one semiconducting layer, at least one stratified insulation made from windings of at least one paper-polypropylene laminate, the stratified insulation being impregnated with at least one electrically insulating fluid having a kinematic viscosity of at least 1,000 cSt at 60EC, wherein the laminate includes at least one paper layer having an air impermeability of at least 100,000 Gurley sec?1. Such a high air impermeability of the paper layer(s) remarkably reduces the swelling of the polypropylene layer(s) during impregnation with a high viscosity insulating fluid, thus preventing delamination, up to the end of the impregnation process for the whole stratified insulation.Type: GrantFiled: December 16, 2009Date of Patent: March 14, 2017Assignee: PRYSMIAN S.P.A.Inventors: Mauro Maritano, Gianni Miramonti

Patent number: 9279952Abstract: An optical cable for communication includes at least one retaining element blocked with respect to the water propagation as well as a process for manufacturing such an optical cable. The optical cable includes, in addition to the retaining element, at least two transmission elements housed within the retaining element and a water swellable yarn housed within the retaining element. The water swellable yarn is selected according to the following equation: V w V TF = k V t + R ( I ) in which Vw is the volume of the water swellable yarn after swelling upon contact with water; VTF is the total free volume in the retaining element; k is a constant?180; R is a constant?1.4; and Vt is the free volume per each transmission element. Advantageously, the optical cable is water-blocked and the water swellable yarn does not induce microbending effects on the transmission elements.Type: GrantFiled: November 16, 2010Date of Patent: March 8, 2016Assignee: PRYSMIAN CAVI E SISTEMI ENERGIA S.R.L.Inventors: Alessandro Ginocchio, Enrico Consonni, Paolo Arturo Presa, Massimo Pizzorno, Mauro Maritano

Patent number: 7865047Abstract: Telecommunication cable having an elongated element housing at least one transmitting element. The elongated element has a water-soluble polymeric composition of a vinyl alcohol/vinyl acetate copolymer having a saponification degree of about 60% to about 95%; a plasticizer; a hydrolysis stabilizer compound having a chelant group having two hydrogen atoms bonded to two respective heteroatoms selected from nitrogen, oxygen and sulfur. The two hydrogen atoms have a distance between each other of 4.2×10?10 m to 5.8×10?10 m. The stabilizer compound is present in an amount of at least 0.75 mmoles per 100 g of copolymer. The elongated element is in particular a buffer tube housing a plurality of optical fibers. The presence of the stabilizer reduces the increase of the hydrolysis degree of the copolymer upon aging, thus maintaining the desired water blocking properties of the copolymer.Type: GrantFiled: December 19, 2002Date of Patent: January 4, 2011Assignee: Prysmian Cavi e Sistemi Energia S.R.L.Inventors: Mauro Maritano, Raffaella Donetti, Antonio Campana, Massimiliano Pavan, Raimondo Scordamaglia
