Testurteil Enlarged view of image

  • Test result: Very good

Zitat aus der Stereoplay: "Sehr stimmige, klangfarbenreiche und räumliche Wiedergabe, gutes timing. Verliert auch im Orchester nicht die Übersicht." ...

"...Noch aufwendiger zu konfektionieren ist der einzige Koax-Leiter dieses Tests, das Sommer Cable MAGELLAN, das zudem eine halogenfreie Isolation besitzt. ... Doch die Mühe lohnt sich. Konstruktionsbedingt besitzt es eine niedrige Induktivität und ist deshalb besonders empfehlenswert für längere Strecken. Außerdem überzeugt es mit fein aufgelösten Höhen, schönen Klangfarben und guter Sprachverständlichkeit."

Eigenschaften

 
    Analog cables are used to transmit low frequency audio signals and to connect microphones, speakers and many other audio components.

    In case of fire this cable will not develop any gases that are poisonous to humans, e.g. chloride. This is often a requirement in public buildings. But careful! A halogen-free cable is flammable and normally a flame-resistant effect, known as FRNC (halogen-free and flame-resistant), is required.

Low in fumes
If cables or wiring with insulation or jackets (e.g. made of PVC) containing chlorine burn, dense black fumes will be the result. Halogen-free cables or wiring only develop approx. a tenth of the fume density when compared to PVC-cables or wiring – they are thus considered to be low in fumes.

    These cables comply with the generally valid fire protection guidelines. They are halogen-free and flame-resistant. This guideline is classified.

EXPLANATION of testing procedures according to VDE 0472, Part 804:
FRNC Test Type A

A cable sample measuring 60 cm in length is vertically suspended in the center of a metal box (height 1200 mm x width 300 mm x depth 400 mm). A gas burner with a de? ned ? ame is ? xed, so that its axis is tilted by 45° in reference to the vertical. The ? ame hits the cable sample about 100 mm from the lower end. The ? ame hits until the conductor or the top most metal shielding emerges, but no longer than 20 seconds. The test is successful if the test sample did not burn or if the ? ame that resulted extinguishes itself and the damage caused by the heat of the ? ame did not reach the upper end of the test sample.

FRNC Test Type B

A cable sample measuring 60 cm in length is vertically suspended in the center of the metal box (height 1200 mm x width 300 mm x depth 400 mm). A gas burner with a de? ned ? ame is ? xed, so that its axis is tilted by 45° in reference to the vertical. The ? ame hits the cable sample about 100 mm from the lower end for about 1 – 2 minutes, depending on the weight of the sample. The test is successful if the test sample did not burn or if the ? ame that resulted extinguishes itself and the damage caused by the heat of the ? ame did not reach the upper end of the test sample.

FRNC test type C

Cable samples, each measuring 360 cm in length, are fastened side by side to a ladder-like test rack. This test rack is inserted vertically into a kiln, at a distance of 150 mm to the back of the kiln. The cable samples are reached by the ? ame at a height of approx. 60 cm, at a temperature of approx. 800 °C, by a burner of approx. 250 mm in width. The exposure time is 20 minutes. The test is successful if the ? ame that resulted extinguishes itself and the damage caused by the heat of the ? ame did not reach the upper end of the test sample.

    SOMMER CABLE mostly uses oxygen-free (OFC) or low-oxygen copper. For your information: Copper has a specific resistance of 0.0178 Ω per meter, at a diameter of 1 mm². The purer the metal, the smoother it is (high bending cycles!) and the more consistent this value will remain over the years.

    A granular mix on a PVC-basis, also exclusively developed for SOMMER CABLE. S-PVC is a super soft PVC with the “feeling“ and ? exibility of a soft rubber hose cable, but with signi? cantly more resistance to notching and cold temperatures than most standard PVC-jackets. While most jacket mixtures already start tearing during mobile application of –10 °C, the S-PVC withstands temperatures of –30 °C.



Description of Article:

Quietly the snow falls...

Similar to the background music and the animated sales announcements made in department stores. For this purpose, we have the perfect cable: a coaxial cable is used where a small outer diameter with a large outer diameter is needed. Especially for cable conduits where the speaker cable is located next to cables with strong interference.Normally shielding made of braided copper strands is used for coaxial cables. This makes them unnecessarily stiff and non-flexible, making multiple winding almost impossible. We use a double counter-rotating shield for our cables SPK. This offers better shielding than the conventional copper braiding and makes the cable unbelievably flexible.

When used as a speaker cable the twisted shielding is used as a second conductor. It has the same diameter as the inner conductor.



Application

    For installation in buildings
    Combination with small plug connectors (jack, XLR, etc.)
    Wiring of HiFi-systems
    High-end HiFi-applications


 
    These cables are optimized for sound. The special stranding or wire stranding along with perfect shielding will provide enduring listening pleasure and perfect transmission. They are used in the studio setting, in broadcasting, and in transmission vehicles.

    Cables for installation are in the first place designed for longevity and safe transmission, especially for ELA-technology. They can be wired inside buildings over long distances, but also inside audio units (amplifiers, speakers, etc.) or control cabinets. If you have special fire protection requirements, please observe the halogen-free/ PUR and FRNC symbols.

    These cables can be used to transmit and control 100 V technology. Basically almost all LF- and speaker cables in our program are suitable for use in ELA-technology. We use high quality materials for the insulation, such as PE, SPVC, PUR, Hytrel, and PP. The test voltage for our LF-cables is 1200 V, the operating voltage 300 V. The main problem in ELA-technology are the long distances to be covered. The user has to calculate them.

    These cables are optimized for sound and were developed for true, i.e. electrically and acoustically linear transmission of audio signals. For example, you can connect amplifiers, speakers, CD-players, and other audio units. They are also recommended for the ambitious studio operator.

Note

This article is sold by the meter thus the price refers to 1 meter of cable. If you need more than one meter you need to raise the amount accordingly. For example 2 items equal 2 meters of cable, 3 items equal 3 meters and so forth.

These cables are not pre-assembled which means they are delivered without connectors and such.
