Description

DESCRIPCIÓNDESCRIPTION

Procedimiento de fabricación de un cable de suministro eléctrico y de transmisión de datos y producto obtenidoManufacturing procedure of an electrical supply and data transmission cable and product obtained

SECTOR DE LA TÉCNICATECHNICAL SECTOR

La presente invención se refiere a un procedimiento para la fabricación de un cable eléctrico destinado tanto al suministro eléctrico como a la transmisión de datos.The present invention relates to a process for the manufacture of an electrical cable intended for both electrical supply and data transmission.

El objeto de la invención es proporcionar un cable sumamente versátil con alta capacidad de transmisión de datos y con una estructura que evita su calentamiento y que además reduce sensiblemente su peso.The object of the invention is to provide an extremely versatile cable with a high data transmission capacity and with a structure that prevents it from heating up and that also significantly reduces its weight.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Los actuales cables eléctricos de cobre o aluminio presentan una problemática con una doble vertiente:The current copper or aluminum electrical cables present a problem with two aspects:

Por un lado en la conducción de la corriente a través de los mismos generan calor, lo que se traduce en pérdidas energéticas.On the one hand, when conducting current through them, they generate heat, which translates into energy losses.

Paralelamente, presentan un elevado peso en relación a su capacidad de transmisión de corriente, lo que también sería deseable mejorar.At the same time, they have a high weight in relation to their current transmission capacity, which would also be desirable to improve.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

El cable eléctrico y de transmisión de datos que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución sencilla pero eficaz, reduciendo drásticamente su peso y optimizando el rendimiento energético.The recommended electrical and data transmission cable fully satisfactorily resolves the aforementioned problems, based on a simple but effective solution, drastically reducing its weight and optimizing energy performance.

Para ello, el cable de la invención centra sus características en el hecho de que sus hilos conductores y de transmisión de datos en vez de estar obtenidos en aluminio o en cobre, están obtenidos a base de finas capas de film de grafeno.To this end, the cable of the invention focuses its characteristics on the fact that its conductive and data transmission wires, instead of being made of aluminum or copper, They are obtained from thin layers of graphene film.

De forma más concreta, el cable se constituye a partir de una pluralidad de films de grafeno distribuidos en capas, de manera que a partir de un reactor químico de deposición por vapor CVD (Chemical vapor deposition), sobre una base se deposita el grafeno que procede de la descomposición bien sea de metano, biogás, dióxido de carbono o metanol.More specifically, the cable is made from a plurality of graphene films distributed in layers, so that from a chemical vapor deposition CVD (Chemical vapor deposition) reactor, the graphene is deposited on a base. It comes from the decomposition of either methane, biogas, carbon dioxide or methanol.

Una vez obtenido el grafeno en la base, se procede a traspasar la capa obtenida de grafeno sobre una capa de material aislante, superponiéndose sobre dicha capa de grafeno tantas capas como se estimen convenientes, en función de la intensidad máxima de corriente prevista para el cable, disponiéndose en último lugar una capa de material aislante, libre de halógenos como envolvente final, conjunto que se hace pasar a través de un rodillo térmico de prensado para obtener así un cable compacto, ligero y que no se calienta durante su uso.Once the graphene has been obtained in the base, the obtained layer of graphene is transferred onto a layer of insulating material, superimposing on said layer of graphene as many layers as deemed appropriate, depending on the maximum intensity of current foreseen for the cable. Finally, a layer of halogen-free insulating material is arranged as the final envelope, which is passed through a thermal pressing roller to thus obtain a compact, lightweight cable that does not heat up during use.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas, puede observarse como en el cable de la invención participan sendas capas extremas de material aislante (1-1’) suministrados a partir de dos rollos de film de sustrato incorporados en el propio proceso de fabricación del cable, libre de halógenos, entre las que se van depositando una a una capas a base de film de grafeno (2,2’,2’’,2’’’,2iv, 2v, 2vi...), tantas capas como se estime necesario en función de las prestaciones previstas para el cable, capas que, se obtienen de forma independiente a partir de un reactor químico de deposición por vapor por descomposición (4), con sus correspondientes medios de control (5) de entrada de diferentes gases, tal como biogás (6), argón (7), hidrógeno (8), nitrógeno (9), metano (10), biometano (11) o dióxido de carbono (12), gases que, a la salida del reactor pueden ser desechados a través de una salida (13), o bien reutilizados a través de un circuito de recirculación (14), en caso de que todavía puedan ser reaprovechados, siendo éstos impulsados por una bomba de vacío (15).In view of the figures outlined, it can be seen how the cable of the invention involves two end layers of insulating material (1-1') supplied from two rolls of substrate film incorporated in the cable manufacturing process itself, halogen-free, among which layers based on graphene film are deposited one by one (2,2',2'',2''',2iv, 2v, 2vi...), as many layers as estimated necessary depending on the expected benefits for the cable, layers that are obtained independently from a chemical decomposition vapor deposition reactor (4), with its corresponding means of control (5) of input of different gases, such as biogas (6), argon (7), hydrogen (8), nitrogen (9), methane (10), biomethane (11) or carbon dioxide (12), gases that can be discarded at the reactor outlet through an outlet (13), or reused through a recirculation circuit (14), in case they can still be reapr harvested, these being driven by a vacuum pump (15).

La instalación incluirá un controlador de entradas de gases de proceso y un controlador de giro de las bobinas.The installation will include a process gas input controller and a coil rotation controller.

De esta forma, se parte de un rollo (16) a partir del que se suministran las capas de aislante (1-1’), que al hacerse pasar por el reactor sobre una de dichas capas de aislante se van depositando las capas de film de grafeno obtenidas por la descomposición de los gases, de manera que, tras la aplicación de la última capa de film de grafeno (2vi), y la complementaria capa aislante (1’) eléctrica, el conjunto se hace pasar a través de un sistema de prensado (3) mediante rodillo térmico, obteniéndose así el cable debidamente aislado en un rollo (17), libre de halógenos y que, como se ha dicho anteriormente presenta un peso sensiblemente menor que cables convencionales con la misma capacidad, y no se calienta durante su uso.In this way, it starts from a roll (16) from which the layers of insulation (1-1') are supplied, which when passed through the reactor on one of said layers of insulation, the layers of film are deposited of graphene obtained by the decomposition of gases, so that, after the application of the last layer of graphene film (2vi), and the complementary electrical insulating layer (1'), the assembly is passed through a system of pressing (3) by means of a thermal roller, thus obtaining the cable duly insulated in a roll (17), free of halogens and which, as has been said previously, has a significantly lower weight than conventional cables with the same capacity, and does not heat up during use.

Los gases descompuestos y a partir de los que se obtiene el grafeno pueden estar obtenidos a partir de los gases generados en la digestión anaeróbica de residuos orgánicos, sin empleo de metales, de modo que el cable puedan considerarse como un producto ecológico de origen renovable, todo ello con un peso sensiblemente menor que los cables convencionales de cobre o aluminio. The decomposed gases from which the graphene is obtained can be obtained from the gases generated in the anaerobic digestion of organic waste, without the use of metals, so that the cable can be considered as an ecological product of renewable origin, all this with a significantly lower weight than conventional copper or aluminum cables.
