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.
		A PUR-jacket is extremely tough, especially resistant to the cold (–40 °C), yet easy to wind even at minimal temperatures. At SOMMER CABLE we usually give our cables a halogen-free PUR-jacket, which is, aside of the advantages mentioned above, very tolerant to heat and sunlight. This jacket is a little more expensive than the standard PUR-mixture, but is meanwhile required and preferred by almost all broadcasting companies and professional installers.
		This seemingly unimpressive identification code stands for an important description of continuous function in case of fire. This fire protection class is based on DIN VDE 0815/DIN VDE 4102 (Part 12) and stands for improved performance in case of a fire, compared to e.g. common FRNC-cables. In compliance with this norm, E30 guarantees continuous function for 30 minutes. Please note that it is not possible to manufacture all cables accord. to E30 or even E90, because the insulation on some cables does not comply with the norm stated above.
		All cables identified with AQUA are watertight up to a water pressure of 20 bar. The special PUR-jacket keeps water and other fluids from penetrating and prevents longitudinal dispersion in case of cable damages. The watertight jacket is also robust enough to handle the installation of high-pressure end sockets inevitably needed to prevent moisture from penetrating. Penetrating water not only speeds up the oxidation process, but will, due to the capillary action, alter the damping and other relevant electrical values. Here, video cables and other coaxial cable types are especially jeopardised, e.g. on monitoring cameras or monitors.Starting at a length of 2,000 m almost all our cables can be manufactured with this jacket. Prices and delivery times are available upon request.Caution: Watertight does not mean “oceanic water tight” or “salt water tight”!
		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.
		The Pur Master Blend has a jacket mixture on a polyurethane basis, especially developed for SOMMER CABLE. The jacket on the PMB is resistant to notching and cold temperatures (–40 °C) and free of adhesion with a surface that is easy to clean. PMB offers the toughness and temperature resistance of PUR and the ? exibility of PVC. PMB is not halogen-free or ? ame-retardant.

Description of Article:

When the wires run hot...

The crowd cheers when the speakers are turned up all the way. Then not only the spirits heat up, but also the cables. This places very high demands on the cable and the outer cable jacket must be as thick as elephant skin. It but should, however, also be flexible, treadable, easy to wind and of course reusable. Especially mentioned should be the combi-special cable ELEPHANT SPM4025 for woofers and surround systems. The SPM4025 has a total of 6 wires, 4 for the bass range with a diameter of 4.0 mm² and 2 wires for the high frequency range with a diameter of 2.5 mm². Based on this stranding technique commonly used for HiFi-cables the SPM4025 transmits a crystal clear high frequency range and a clean, dynamic bass signal.

Compare them to other speaker cables. The ELEPHANT will convince you!

Application

		Professional PA/sound systems
		For ELA-technology
		Surround und woofer systems
		For fixed installation in building technology

		Cables for application especially on the stage, for open air festivals, or live events. These cables are easy to wind, simple to handle and will not knot, by using in correct way, so you can't trip when being laid out on stage. They are ideal for the professional and occasional musician.
		Cables for mobile application distinguish themselves through the flexible PVC jacket, a fine-stranded wire construction, high bending cycles, and a low bending radius. They are easy to wind and suitable for outdoor application. For extreme outdoor applications (transmission vehicles, transmission of sporting events, etc.) we recommend the version with a PUR or TPE-jacket. This jacket used on SOMMER CABLEs is extremely resistant to notching, is halogen-free, and also resistant to heat.
		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.
