导体6的大小截面按传输信号的电流大小来确定。一般按国际通用的截面选择相近的导体6。绝缘层7的厚度与导体6的直径关系是关键数据,需要按传输信号的特性阻抗来设计。目前常用的信号特性阻抗主要有25Ω、35Ω、50Ω、75Ω、95Ω或135Ω等。其导体6外径和主电源线1外径(导体6+绝缘层7厚度)的比例是不同的。特性阻抗越大,绝缘层7越厚,比例值越大。同一特性阻抗的比例只是相近,也不是一样的。这个需要设计时进行理论计算和生产后测试调整到最佳。屏蔽层2和隔离层3采用编织加铝箔全屏蔽结构,屏蔽效果突出,同时对主电源线1起一定保护和固化作用,使得主电源线1间的位置稳定,阻抗均匀性更好。护套层只是起保护作用的,也有少量固化平行结构作用,稳定阻抗均匀性,在柔软度和安装空间合适的情况下可以适当加厚。The size cross section of the conductor 6 is determined by the magnitude of the current of the transmitted signal. Generally, the conductors 6 are similarly selected according to the international common cross section. The relationship between the thickness of the insulating layer 7 and the diameter of the conductor 6 is a key data and needs to be designed in accordance with the characteristic impedance of the transmission signal. At present, the commonly used signal characteristic impedances are mainly 25 Ω, 35 Ω, 50 Ω, 75 Ω, 95 Ω or 135 Ω. The ratio of the outer diameter of the conductor 6 to the outer diameter of the main power supply line 1 (the thickness of the conductor 6 + the insulating layer 7) is different. The larger the characteristic impedance, the thicker the insulating layer 7, and the larger the proportional value. The ratio of impedances of the same characteristic is only similar and not the same. This requires theoretical calculations and post-production test adjustments to be optimal. The shielding layer 2 and the isolation layer 3 adopt a woven and aluminum foil full-shielded structure, and the shielding effect is outstanding, and at the same time, the main power supply line 1 is protected and solidified, so that the position between the main power supply lines 1 is stable, and the impedance uniformity is better. The sheath layer is only protective, and has a small amount of solidified parallel structure to stabilize the impedance uniformity, and can be appropriately thickened in the case of softness and suitable installation space.
