低噪音电缆
Low Noise cable
描述
低噪音电缆的用途是将因为颤噪效应引起的电缆内部的噪音与干扰降至 。普通电缆在接触外部干扰，比如轻微接触、常规移动与振动时会产生不必要的电气噪音。这些干扰足以影响电缆传输的信号，造成数值错误。低噪音电缆适用于各类高敏感精密设备，通常是涉及极低电流的检测或测量。
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.
低噪音电缆的制造
半导电层位于电缆线芯与外护套之间，这也就意味着，移动或压力形成的任何电荷都可在包套之间迅速来回，有效地捕获不必要的信号，从而不会有任何电荷到达电缆所连接的设备。该方法的减噪作用比普通电缆要好1000倍以上。
Low-noise
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.
在配合极度敏感仪器及最极端环境使用方面还有另外一类精细的版本，超级低噪音电缆可以承受更大的外部影响，比如突然撞击，而不会产生任何噪声信号。设计导入了多层半导电层，相对于标准低噪音电缆，可以将减噪效果再提升1000倍，比普通电缆要好10万倍。
超级低噪电缆还成功通过了将其内外导体挤压到直接相互接触的破坏性测试。
Super-low-noise
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.
