Such as machine tool processing e, logistics delivery system, port machinery, complete e installation engineering. Product features: according to customer re, color core or coding core. High PVC mix is adopted to reduce the re of cable outer diameter for installation space. The designed cycle bending life is 5 million times, and the actual use has exceeded 6 million times. Cable structure: conductor: using multi-strand fine ground and other fine twisted into a bundle conductor oxygen-free copper wire, conform to DIN VDE 0295 grade 6 insulation: high PVC mixture color: color line core or coding line core 3 core + yellow or green conductor sheathed: high PVC mixture color: black, grey, orange electrical characteristics: rated voltage U0 / U < 0.5 was 300/300 V p o. 5 was 300/500 V test voltage: 3000 V U meet DIN VDE 0281 part 2 temperature range: ℃ mobile installation: fixed installation: - 5 ℃ ~ + 70 ℃ and 30 ℃ ~ + 70 ℃ when continuous movement, the minimum bending radius: 7.5 x cable diameter

绝缘材料:高密度聚乙烯或乙/丙共聚物,绝缘线的颜色符合全色谱标准。绝缘线对:二根不同颜色的绝缘线按不同的节距扭绞成对,采用规定的色谱组合以便识别。缆芯结构:以25对为基本单位,超过25对的电缆按单位组合,每个单位用规定色谱的单位扎带绕扎,以便识别不同的单位。
实时性的保证为保证实时性,要求轮询表包含每个从站号不能少于一次,这样在周期轮询时,每个从站在一个周期中至少有一次机会取得总线使用权,从而保证了每个站的基本实时性。对于实时性要求比较高的站,可以在轮询表中让其从机号多出现几次,这样就用静态的方式赋予该站较高的通信优先权。在有些主从总线中轮询表法与中断法结合使用,让紧急任务可以打断正常的周期轮询而插入,获得优先服务,这就是用动态赋予某项紧急任务以较高优先权。
备注:网络销售追求的是量大,量大必然价低,价低并不代表我们的产品质量差,我们的产品都是在保证质量的前提下,厂家尽量放低利润给用户,绕过经销商中间环节,我们追求的是低利润和快速资金回笼.希望您是我们下一个合作的客户。

适用范围:适用于高速公路中紧急电话通信系统用于传输音频信号及控制信号。绝缘1绝缘应采用符合规定的高密度聚乙烯。2绝缘线芯采用颜色识别标志,绝缘颜色识别应均匀,并采用下列颜色:星绞:白、蓝、红、绿单元线组星绞组绝缘线芯按白、蓝、红、绿顺时针排列。
串联接线这种接线应用广,也普遍,因为布线方便。但是问题来了,接线的时候是把两线破皮后插入接线柱再拧紧螺丝还是把两线铰接在一起插入接线柱再拧紧螺丝?看起来都接上了,但是效果却差别很大。1,如果电工师傅按前者的方式接线,没有把导线铰接在一起。一个插座坏掉了。接线柱位置有可能烧坏,两根导线分离,后面串的插座全部断电。2,铰接到一起的,涮锡后插入,这样即使接线柱烧坏,两根导线还是连在一起,不影响后面的插座。
