Development of production technology of composite core based on nano-fibers for aluminum heat-resistant wires – Russian analogue of ACCR wire.

The existing ACCR (3M companies) wires on the market have significant advantages, such as:

  • High current carrying capacity (one line can replace up to three currently in operation);
  • Complete absence of the possibility of icing;
  • A significantly larger distance between the supports of power transmission lines, etc.

The objective of this project is to develop a domestic commercial analogue of the composite material for the core fibers, which is an important direction for the cable industry of the Russian Federation.

A distinctive feature of the proposed solution: development of a fundamentally new type of continuous fibers of aluminum oxide reinforced with nanofibers of aluminum oxide or mullitecorundum.

In fact, it is proposed to obtain a composite fiber of the aluminum oxide-aluminum oxide system.

ABOUT THE PROJECT

  • Production original harness from nano-fibers;
  • Treatment of harness by analogue molding solution;
  • Subsequent drying;
  • Special heat treatment.

The technology of obtaining continuous fibers from aluminum oxide is based on:

  • Forming fibers from a viscous forming solution;
  • Its subsequent drying;
  • Special heat treatment
  • The technology is much simpler and more economical than the existing one;
  • Obtained fibers have increased mechanical and thermal characteristics, which allows to increase the operational and economic parameters of the final product-wires for power lines;
  • The proposed technology is not currently described in technical sources, has a number of significant technological advantages, and is able to create fibers with high mechanical characteristics and the required level of TCLE (temperature coefficient of linear expansion) for use as a power core of domestic heat-resistant wires for power lines with high capacity.

Such fibers can also be in demand in other industries in the creation of heat-shielding materials and structures, power elements of new equipment (transport, aviation, space, etc.)

1. In Russia, a new type of fiber will be developed and commercialized — NKNO fibers, allowing to solve a significant range of issues, including the strategic nature, currently limited by the international embargo on all types of fibers.

2. In Russia, a new type of core based on nanofibers for aluminum heat – resistant wires of power lines will be developed and put into commercial use- the Russian analogue of 3M ACCR wire, which allows in the foreseeable future to master the production of the newest types of energy-saving wires for power lines at the domestic production base.

The project actually solves the problem of import substitution in two significant positions that determine the development of the Russian Federation in the knowledge-intensive field and in the field of energy efficiency.

  1. Development of continuous composite nanostructured fiber (CCNF) system of Aluminum Oxide-Aluminum Oxide Nanofibers
  2. Development of continuous composite nanostructured fiber (CCNF) system of Aluminum Oxide-Aluminum Oxide Nanofibers
  3. Research of properties of the received material and transfer of samples of a composite wire for testing to potential consumers and customers
  • Development of a method for obtaining a primary harness from nanofibers;
  • Treatment of the primary harness with molding solution;
  • Drying of the treated harness with molding solution;
  • Heat treatment to form the final structure of the CCNF fiber;

  • Development of a method for obtaining a secondary CCNF harness;
  • Investigation of mechanical and physical and chemical properties of the wire obtained from the composite material;
  • Transfer of composite wire samples for testing to potential consumers and customers;
  • Carrying out works on patenting the achieved results;
  • Marketing activities to promote the achieved results on the Russian and foreign markets.
  • Development of a method of forming aluminating composite material reinforced with CCNF in the form of wire;
  • The accumulation of the experimental samples of wire of a composite material Al — CCNF fiber;
  • Investigation of mechanical and physical and chemical properties of the wire obtained from the composite material;

  • Conducting marketing activities to promote the achieved results on the Russian and foreign markets.

1. It is planned that the users of the project will be manufacturers of wires for power lines of the new generation (analogues of 3M ACCR wire). Implementation of the project completely removes technological risks of creation of the new type of wires demanded in the domestic market of Russia and the international energy market.

2. After the implementation of the project, a domestic company for the production of CCNF on an industrial scale will be established to meet the demand in the domestic Russian and international market for high-tech products with a high level of added value. Implementation of the project completely removes technological risks of creation of new type of fibers and opens real prospect of their commercialization.

3. Users of the project will be manufacturers of high-tech innovative products based on CCNF fibers in various areas of Russian production in the creation of heat-shielding materials and structures, power elements of new equipment (transport, shipbuilding, aviation, space, etc.).

4. Implementation of the project brings this type of fiber to the domestic Russian market and opens up prospects for the development of new materials and structures.

1. A stronger fiber will be developed and a composite material based on aluminum with higher strength and improved performance will be created;

2. Proposed solutions have higher economic efficiency in terms of simplicity of technological solutions;

3. Proposed solutions have patent purity and do not intersect with known technological processes;

4. Initial components and materials of the proposed solution are commercially available and non-scarce;

5. Proposed solutions do not require complex technological equipment and can be implemented on an industrial scale in Russia;

6. Proposed technological solutions are import-substituting and are aimed at reducing Russia’s technological dependence on Western technologies.
