Pure silver digital transmission
In order to maximize the potential of material, we believe that it is necessary to have the highest level of technology and method on the basis of the experience and the data.
We conceived of the idea of making a cable using pure silver which has the highest electrical conductivity of all metals.
The FTVS-408, a coaxial cable, was designed to be mainly used for digital signal transmission. Although it was produced as a limited production model, it became a regular product in our lineup due to strong to customer demand.
Doing further validation of FTVS-408, we devoted much energy to providing the finest 5N silver and researching the perfect insulator and shield for the silver conductor. It was designed to be used for antenna, sound and digital signal transmission.
ConductorPure silver is the best material for high-speed transmission due to its excellent electrical conductivity which is far superior to high-purity copper. However, the price of silver continues to rise ever higher making it one of the rare metals. For the core of FTVS-510, 5N jewelry grade pure silver, which is far better than industrial grade, is used. After being melted in a ceramic crucible, it is molded into 15mm diameter round bars. It is further reduced in diameter by means of 19 repetitions of the cold rolling process. |
InsulationAlthough the conductor is the most important factor in signal transmission, the insulator is also significant in enhancing the transmitting capabilities of the cable.For the purpose of lessening signal loss, we employed Teflon which provides excellent electrical isolation and low electric permittivity. For the first insulation layer, we selected PE (Polyethylene) which keeps permittivity to a minimum and enhances the flexibility of the cable. This layering of these different materials not only enhances the conductor's electric capabilities but also attenuates internal vibration by altering the resonance point. |

Semiconductor LayerAlthough Teflon has a great electric characteristic, we needed to adopt a method for static electricity removal due to the fact that Teflon charges easily. |
Triple-shielding structureThe ultra silent background of the FTVS-510 is provided by a triple-layered shielding structure. |

The exteriorThe clear urethane sheathing has the excellent mechanical strength and always maintains a stable level of hardness without being affected by temperature change. Moreover, due to its high shock absorption and degree of elasticity, polyurethane provides powerful isolation from vibrations. |
