簡(jiǎn)介：
本產(chǎn)品適用于額定電壓500V及以下對(duì)于防干擾性要求較高的電子計(jì)算機(jī)[1]和自動(dòng)化連接用電纜。電纜地線芯絕緣采用具有抗氧化性能的K型B類(lèi)。
低密度聚乙烯聚乙烯的絕緣電阻高，耐電壓好，介電系數(shù)小和介質(zhì)損耗溫度和變頻率的影響也小，不但能滿足傳輸性能的要求，而且能確保電纜的使用壽命。
為了減少回路間的相互串?dāng)_和外部干擾，電纜采用屏蔽結(jié)構(gòu)。電纜的屏蔽要求是根據(jù)不同場(chǎng)合分別采用：對(duì)絞組合屏蔽、對(duì)絞組成電纜的總屏蔽、對(duì)絞組合屏蔽后總屏蔽等方法。
Introduction:
This product is suitable for electronic computers with a rated voltage of 500V and below, as well as cables for automation connections that require high anti-interference requirements. The insulation of the cable ground wire core adopts K-type B class with oxidation resistance.
Low density polyethylene has high insulation resistance, good voltage resistance, low dielectric coefficient, and minimal influence of medium loss temperature and frequency variation. It not only meets the requirements of transmission performance, but also ensures the service life of the cable.
In order to reduce mutual crosstalk and external interference between circuits, the cable adopts a shielding structure. The shielding requirements for cables are based on different occasions, using methods such as twisted pair combination shielding, total shielding of twisted pair composed cables, and total shielding after twisted pair combination shielding.
cable
屏蔽材料有圓銅線，銅帶、鋁帶/塑料復(fù)合帶三種。屏蔽對(duì)與屏蔽對(duì)具有較好的絕緣性能，電纜在使用中若屏蔽對(duì)屏蔽對(duì)之間出現(xiàn)電位差時(shí)，不會(huì)影響信號(hào)的傳輸質(zhì)量There are three types of shielding materials: round copper wire, copper strip, aluminum strip/plastic composite strip. Shielded pairs have good insulation performance, and if there is a potential difference between shielded pairs during cable use, it will not affect the transmission quality of the signal.
