SK-GK-NFE-BW
Product information "SK-GK-NFE-BW"
For connecting devices or active speakers with IEC connectors of protection class I to the 230V power grid.
Power cables can have a greater impact on sound quality than, for example, signal cables. The power cables themselves do not have a sound character, but they differ in how they suppress and shield high-frequency interference, which the devices cannot protect themselves from. Conventional power filters, as built into most devices, suppress frequencies up to about 50 MHz. However, it is precisely the higher interference frequencies (mobile networks: 900 MHz to 2.6 GHz) where devices are particularly sensitive, and these can only be effectively suppressed with a ferrite filter section. In addition to a continuous ferrite coating on the phase, neutral, and ground conductors, the SK-GK-NFE-BW features a foil shield and an outer covering made of pure cotton, which, by absorbing natural humidity, dissipates static charges and high-frequency leakage currents from the surface of the cable jacket. The foil shield is galvanically grounded at the Schuko plug and capacitively grounded at the IEC connector, ensuring that the shielding is connected on both sides at high frequencies and on only one side at low frequencies, preventing equalization or leakage currents from flowing through the shielding foil. Only the combination of all these characteristics guarantees interference-free operation of the connected device; other features (oversized copper cross-section, gold-plated plugs, etc.) are comparatively insignificant or even harmful (e.g., plastic mesh covering) to the resulting sound quality.
Since the ferrite coatings make the cable conductors thicker and less flexible, a copper cross-section of 3 x 1 mm² was deliberately chosen, which is sufficient for a continuous power output of up to 2.3 kW. A larger copper cross-section is oversized for hi-fi devices and impractical to handle.
In combination with our 4-way, 6-way, or 8-way power strip with star-wired internal cabling, the SK-GK-NFE-BW forms perfect power cabling systems for high-end systems and studio equipment that work without limitation at any standard wall socket.
