Low Noise cable
The purpose of low-noise
Due to the effects of microphony, ordinary cables generate unwanted electrical noise when exposed to external influences such as light contact, general movement and vibration. This interference can be sufficient to affect the signal being transmitted through the cable resulting in incorrect values. Our low-noise cables are suitable for use in, or with highly sensitive precision equipment; generally involving the detection or measurement of extremely small currents.
An integral carbon layer is applied between the core/s and the overall screen of the cable. This means that any electrical charge formed by movement or pressure are rapidly returned to and from the screen, effectively trapping these unwanted signals so that no charge can reach the equipment that is connected to the cable. The noise reduction resulting from this method is in the order of one thousand times better than that of an ordinary cable.
A further refined variant is available for use with extremely sensitive instruments and the most extreme of environments. Super low-noise cables can withstand even greater external influences such as sudden impact without generating any noise signals. The design incorporates several semi-conducting protective layers throughout which in turn improve the noise reduction value by a further factor of a thousand in comparison to standard low-noise cables. Super-low-noise cables have also successfully passed destructive testing where the inner and outer conductors are squeezed until they come into direct contact with one another. During this test, the cable exhibits a noise level in the order of 0.05 pC.
