到目前為止國內(nèi)對音響線材還沒有統(tǒng)一的標(biāo)準(zhǔn)，但是電源線的好壞直接影響系統(tǒng)的音質(zhì)和安全，大家在選購時也要遵循一般的標(biāo)準(zhǔn)，確保選擇的電源線質(zhì)量能夠得到保證。

1、正規(guī)的電源線，絕緣膠皮采用全新的抗氧化PVC塑料，線芯導(dǎo)體采用隔絕空氣法制造的無氧銅(OFC)或鍍錫銅、或鍍銀銅，經(jīng)過精密設(shè)備精工制造而成。只有純無氧銅制造的，才是導(dǎo)電率高、安全又較經(jīng)濟(jì)的電源線，最好是帶屏蔽具有抗干擾作用的。
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、優(yōu)質(zhì)的電源線不僅絕緣性、耐熱性好，而且線芯導(dǎo)體采用七股對絞或編織，這樣才有足夠的密度使其降低電阻值、電容量和電感量，因而輸出足夠的電流量。
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、判斷電源線的優(yōu)劣，不能只看它的外觀尺寸，更重要是看里面銅芯的粗細(xì)與優(yōu)劣。購線材時，建議帶上一把千份尺，到信譽好的線材專門店購買，首先看看電源線導(dǎo)體的表面和截面都是純紫紅色且光鮮，手感柔軟，再用千份尺量一量線的直徑和單支銅絲的直徑，若符合 A規(guī)和B規(guī)標(biāo)準(zhǔn)的，則是標(biāo)準(zhǔn)電源線，否則就是非標(biāo)線。
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、每盤線的實際長度與標(biāo)稱的是否一致，有沒有短斤缺兩的現(xiàn)象。
The actual length of the nominal line is consistent with every dish, there is no Duanjinqueliang phenomenon.
5、選擇電源線的原則是：電流容量值應(yīng)等于或大于與功放相接的保險管的值，選擇合適與否的電源線直接影響音響系統(tǒng)所獲電流與電壓的穩(wěn)定性，如用低于系統(tǒng)電流總量的電源線會產(chǎn)生交流噪聲，且嚴(yán)重破壞音質(zhì)，甚至可能過熱而燃燒。
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.
