Definitions
- the present invention refers to the field of electric wires.
- the patent US 6,399,885 describes cables consisting of a number of wires, positioned in series or in parallel, each one made of a different metal (in particular gold, copper or silver), said wires being insulated from each other and wrapped in a dielectric sheath.
- the wires according to the invention consist of a normal metal wire able to conduct the current, for example a copper wire, the outer surface of which is covered in an alloy containing tin, antimony and copper.
- the various metals constituting the alloy are present in the following concentrations:
- Antimony from 1% to 10%
- the alloy according to the invention consists of Tin 95%, Antimony 4%, Copper 1%.
- the metallic wire is dipped in a bath consisting of the molten alloy. Obviously the time the wire is left in the bath will depend on the temperature of the bath, the type of metal constituting the wire and its dimensions in order to permit deposit of the alloy on the wire without the latter melting or being damaged by immersion for too long at an excessively high temperature.
- the wire is 0.40 mm in diameter
- a bath with temperature between 300°C and 450°C is used, and the wire immersion time is approximately three seconds.
- the metallic wire Before being dipped in the molten alloy bath, the metallic wire is preferably passed through a flux, of the type normally used in the welding of electrical material or in the manufacturing of electric circuits, for example rosin, and then left to dry; the flux improves adhesion of the molten alloy to the wire.
- a flux of the type normally used in the welding of electrical material or in the manufacturing of electric circuits, for example rosin, and then left to dry; the flux improves adhesion of the molten alloy to the wire.
- the wire is pre-heated, for example to a temperature between 60° and 90°C. Examples of production of wires according to the invention are given below. Example 1
- a copper wire, diameter 0.40 mm, is passed through rosin and left to dry; the wire is then pre-heated to 60° - 80°C.
- the wire is then dipped, at a speed of 3 m/min., in a crucible containing a molten alloy consisting of tin (95%), antimony (4%) and copper (1%) at a temperature of approximately 400°C; the immersion time is approximately 3 seconds.
- the wire, on which a layer of alloy is deposited is then left to cool.
- Example 2 Example 1 is repeated using a 0.90 mm wire and dipping it at a speed of approximately 3.3 cm/sec, maintaining the alloy bath at a temperature of approximately 400°C.
- wires according to the invention are suitable for a very wide range of uses, not only as connection cables for low level signals but also for connection cables for power supply, for printed circuit tracks, for coupling, signal, impulse and power transformers, for dipole, array and microstrip antennae, for connectors for signals or power supply and for electromagnetic screens.
- the invention refers to a power transformer, for electric distribution network, of analogue, digital and pulse signals and/or a coupling transformer, the windings of which are made of wires as described above.
- the dielectric sheath used for the transformer according to the invention is made of black silk, preferably woven over the wire itself.
- said transformers permit increase of the dynamics in audio signals, reducing the power supply noise; they also permit increase of the microinformation and ambience and change of the timbre in both recording and reproduction systems; said phenomena are also obtained in coupling transformers.
- Using the power transformer with video systems there was an increase in the colour and contrast and a reduction in noise.
- Transformers for digital signals produced with wires as described above have provided much better results than those produced with other wire materials in the above parameters.
