Graphene cables are deep in the field of high-end cables, and capital giants are rushing to compete!

Graphene is an excellent material for the development of high-end wires and cables

Wires and cables are wire products that transmit electric energy, transmit information, and realize electromagnetic conversion. They are widely used in various fields of the national economy and are referred to as the "blood vessels" and "nerves" of the national economy. It is estimated that by 2020, the output value of my country's wire and cable will exceed 1.7 trillion yuan. From the analysis of the types and grades of products produced, most of the main products of my country's wire and cable enterprises are products with low technical content and product added value. The general characteristics of my country's wire and cable industry are "big but not strong". The development of the traditional wire and cable industry is in the bottleneck period of low-price competition, and new technologies and new materials are needed. Graphene composites have excellent electrical conductivity and mechanical properties and are excellent materials for the development of high-end wires and cables.

Graphene cable has outstanding advantages

Traditional cables have shielding materials that will form an uneven electric field. When the cable is in an uneven electric field, the noise voltage will interfere with the circuit, increase the loss of the internal transmission power of the cable, and cause external electromagnetic radiation pollution. After adding the graphene composite high semiconducting conductor shielding material, partial discharge between the conductor and the insulating layer is avoided. It can improve the power loss and electromagnetic radiation pollution. On the other hand, it can also effectively prevent the external electromagnetic environment from interfering with the signal in the cable to ensure the quality of transmission.

Combined with the extraordinary electrical conductivity of graphene itself, which is dozens of times stronger than steel, graphene cables reduce the power loss of the cable while also increasing their tensile strength. For example, when used in winter, the cable is easy to freeze and cause hanging ice. The environment will greatly improve the working environment and reduce the failure rate.

Giants in the field of graphene cables compete

At present, some industry giants have begun to cut in from the aspects of new materials and new technologies. Aiming at the existing problems of wire and cable materials, they are researching and developing new and industrialized materials in an attempt to find new profit points for the enterprise. With its excellent electrical conductivity and mechanical properties, graphene can effectively solve the problems of power transmission loss and insufficient tensile strength, which is the key point for many wire and cable companies to seek breakthroughs.

At present, the domestic industry is in the R&D stage of capital pursuit. Some companies are still in the stage of capital investment in R&D without releasing results. Some companies have achieved actual breakthroughs and are doing research for industrialization. For example, the mass production of graphene medium and high voltage cables and aluminum-based Graphene composite materials have achieved breakthrough results and so on.
