计算机电缆简要说明：

A₁用途：广州市东方电线电缆厂本产品适用于额定电压500V及以下对于防干扰性要求较高的电子计算机和自动化连接用电缆。电缆地线芯绝缘采用具有抗氧化性能的K型B类低密度聚乙烯。聚乙烯的绝缘电阻高，耐电压好，介电系数小和介质损耗温度和变频率的影响也小，不但能满足传输性能的要求，而且能确保电缆的使用寿命。欢迎浏览网站：//www.cabledf.cebiz.cn   

 为了减少回路间的相互串扰和外部干扰，电缆采用屏蔽结构。电缆的屏蔽要求是根据不同场合分别采用：对绞组合屏蔽、对绞组成电缆的总屏蔽、对绞组合屏蔽后总屏蔽等方法。
    屏蔽材料有圆铜线，铜带、铝带/塑料复合带三种。屏蔽对与屏蔽对具有较好的绝缘性能，电缆在使用中若屏蔽对屏蔽对之间出现电位差时，不会影响信号的传输质量。

2使用于抗干扰性能要求较高的电缆，也可以使用于抗干扰性能较高的检测仪器、仪表连接线用的电缆

电子计算机用屏蔽电缆，选用介电常数小的高压聚乙烯作绝缘。采用对绞、对屏、总屏（或三线组合、组屏蔽、组屏总屏）等结构形式，具有介质损耗小、传输传号能力强、抗干扰性能好等特点，能可靠地传输微弱的模拟信号，可广泛地应用于发电、冶金、石油、化工、轻纺等部门的检测和控制用计算机系统或自动化装置，以及一般的工业计算机上。欢迎浏览网站//www.cabledf.cebiz.cn

Computer Cable brief description:

1Guangzhou Dongfang wire Cable Plant This product is applied to rated voltage 500V and below a higher requirement for tamper-resistant electronic computer and automation connectivity cable. Ground cable core insulation used with anti-oxidant properties of K-B type low-density polyethylene. Polyethylene insulation resistance of a high withstand voltage is good, small and medium dielectric constant temperature and variable frequency of loss of influence is small, not only to meet the transmission performance requirements, but also to ensure that the cable life. Welcome to visit the website: //www.cabledf.cebiz.cn
  In order to reduce the inter-loop crosstalk and external interference, shielded cable structure. Cable shielding requirements are based on different occasions were used: combination of shielded twisted pair, twisted pair cables composed of the total shielding, shielded twisted pair combination of methods such as after the total shielding.
     Shielding materials are round copper wire, copper strip, aluminum strip / plastic composite tape of three. Shield with the shield has good insulation properties of the cable in use of the shield, if shield potential difference between the right, it will not affect the signal transmission quality.
2 for use in anti-interference performance requirements of high cable can also be used in a high anti-jamming performance testing instruments, instrument cable used by cable
Computer to use shielded cable, use a small dielectric constant, high-pressure polyethylene for insulation. Using twisted pair, to screen a total screen (or third-line combinations, group screening, group screen a total screen) and other structural form, with a small dielectric loss, the transmission capacity of transmission numbers strong anti-jamming performance and good features, can be reliably transmitted weak The analog signal can be widely used in power generation, metallurgy, petroleum, chemical, textile and other sectors of testing and controlling a computer system or automated devices, as well as general industrial computers.
