conductor

The center conductor may be said that the world's first, 5N (99.9995%) we used the sterling silver. Silver is the high ideals of the conductor of the most electric conductivity in the metal (silver 61e6 copper 58e6 σ [S / m]), but it was never much use from the price side. Not just for connecting, or communicate without how degrading the image, was the answer is "pure silver".

And this time, perform continuous casting by under a high-frequency electric furnace of advanced production management, cold as many as 19 process rolling, annealing work over twice, drawing process due to the diamond dice, such as skin-pass processing, the high silver purity of not only, we used the "silver wire" there is no gap, high-quality to the grain boundaries.

Insulator

An emphasis on performance and sound quality was a composite insulating layer of PFA (fluorine resin) and FPE (foam polyethylene). PFA is the most dielectric constant of the low insulation, but the feature is not just it. In addition, it is better to insulation in all will dielectric constant is slightly lower, but dare was a composite insulating layer. It is also flexible in the problem, but by using the above all heterogeneous material, the purpose of which is promote the dispersion of the vibration.

Semiconductor layer

When designing this time, that was the most problem was the neutralization of static electricity. PFA is the electrical characteristics is well material, but there is one problem. It is that it charges the static electricity. When the signal flow is weak vibration occurs in the cable, the material is charged static electricity and the corona discharge by the vibration.Therefore, by providing the semiconductor layer on the outer periphery or the inner periphery of the insulating layer, it affects the conductor without, make the release of static electricity.

Two-layer shield

If you are a normal shield the complex, but because copper braid + aluminum foil is common, this is the complex from the frequency band characteristics with each of the metal. The purpose of which is to reflect the noise in a wide band by doing so.

In order to strengthen against "FTVS-408" low-frequency noise, but was a combination of copper tape + tin-plated copper braid, also strengthened against "FTVS-510" further high-frequency noise, high-frequency characteristics we used the silver-plated copper braid (95%).

Exterior

The exterior so that it can also be used outdoors were used for polyurethane of ultraviolet (UV) cut. This also is going to use for a long period of time in the outdoors, the exterior of the deterioration and than conventional products, there is no worry of cracks.
