    易倍体育官网电源线有什么标准?
    2014-10-16 16:37:06

    到目前为止国内对音响线材还没有统一的标准,但是电源线的好坏直接影响系统的音质和安全,大家在选购时也要遵循一般的标准,确保选择的电源线质量能够得到保证。

    1、正规的电源线,绝缘胶皮采用全新的抗氧化PVC塑料,线芯导体采用隔绝空气法制造的无氧铜(OFC)或镀锡铜、或镀银铜,经过精密设备精工制造而成。只有纯无氧铜制造的,才是导电率高、安全又较经济的电源线,最好是带屏蔽具有抗干扰作用的。
    Formal power cord, insulated rubber antioxidant with a new PVC plastic, wire core conductor manufactured using isolated Air Act OFC (OFC) or tinned copper, or silver-plated copper, manufactured by Seiko precision equipment. Only pure oxygen-free copper manufacture, is the high conductivity, safe and more economical power cord, preferably with a shield with anti-interference function.
    2、优质的电源线不仅绝缘性、耐热性好,而且线芯导体采用七股对绞或编织,这样才有足够的密度使其降低电阻值、电容量和电感量,因而输出足够的电流量。
    Not only the quality of the power cable insulation, heat resistance, and the use of the core conductor wire of twisted or braided seven shares, so that a sufficient density so that it can reduce the resistance, capacitance and inductance, and therefore a sufficient amount of current output.
    3、判断电源线的优劣,不能只看它的外观尺寸,更重要是看里面铜芯的粗细与优劣。购线材时,建议带上一把千份尺,到信誉好的线材专门店购买,首先看看电源线导体的表面和截面都是纯紫红色且光鲜,手感柔软,再用千份尺量一量线的直径和单支铜丝的直径,若符合 A规和B规标准的,则是标准电源线,否则就是非标线。
    Judge the merits of the power line, not just because it's the appearance of size, but more importantly is to look inside the copper thickness and the pros and cons. When the purchase of the wire,it is recommended to bring a thousand of feet to wire reputable shop to buy, first look at the surface and cross section of power line conductors are pure purple and bright, soft, and then the amount of one thousand copies foot the amount of wire diameter and the diameter of single wire, if they meet the a and B regulatory compliance standards, it is the standard power cord, otherwise,it is non-standard lines.
    4、每盘线的实际长度与标称的是否一致,有没有短斤缺两的现象。
    The actual length of the nominal line is consistent with every dish, there is no Duanjinqueliang phenomenon.
    5、选择电源线的原则是:电流容量值应等于或大于与功放相接的保险管的值,选择合适与否的电源线直接影响音响系统所获电流与电压的稳定性,如用低于系统电流总量的电源线会产生交流噪声,且严重破坏音质,甚至可能过热而燃烧。
    Select the power line principle is: the current capacity value should be equal to or greater than the value of the amp fuse contact, select the appropriate power cord directly affect whether or not the sound system obtained current and voltage stability, such as the system current with less than the total AC power line will produce noise, and the sound quality is severely damaged and may even overheat and burn.
