双绞屏蔽电缆RS485-2*0.75  的详细介绍
双绞屏蔽电缆RS485-2*0.75 屏蔽双绞线-RVVSP 屏蔽双绞线-RVVSP?屏蔽双绞电缆的选型与传输效果?一种：屏蔽双绞电缆???RVSP?也叫RVVSP?RVVPS屏蔽双绞电缆?结构：聚氯乙烯绝缘聚氯乙烯护套双绞屏蔽电缆，只适用于一般数据的传输，传输距离较近，尤其是其绝缘电阻是让人*不能忍受的只有几十兆欧。价格是双绞线中*低的。?屏蔽双绞线RVSP适用于交流额定电压450/750V及以下的动力、日用电器、仪器、仪表、电讯设备，照明电路以及自动化装置的固定敷设，连接用软线，安装用软线以及干扰较强的场合用屏蔽电线，根据使用环境的需要还可生产此类电线电缆的阻燃类(ZR)、高阻燃类(GZR)，耐温类(90℃、105℃、200℃、250℃)、耐火类(NH)、交联类(YJ)产品。屏蔽双绞线使用环境：?1．?工作温度：一般型不超过70℃，型号后带105的*高不超过105℃。?2．?*低环境温度：固定敷设-40℃非固定敷设-15℃。?3．?额定电压U0/U?450/750V?4．?*小弯曲半径：无铠装层电缆应不小于电缆外径的6倍，带铠装层电缆应不小于电缆外径的12倍。屏蔽双绞线型号、名称型号结构组合方式：?R—软结构电缆?V—聚氯乙烯塑料(PVC)?S—双绞型?P—铜丝编织屏蔽型号、名称屏蔽双绞线。 双绞屏蔽电缆RS485-2*0.75 VSP(又叫RVVSP?RVVPS)规格电缆规格如下：?表1?型号?额定电压(U0/U)?对?数?标称截面(m㎡)?RVSP?RVVSP?RVVPS?450/750V?1，2，3，4，5，6，7，8，10，?12，14，16，19，24?0.5，0．75，?1．0，1．5?**种：RYVPS?结构：聚乙烯绝缘聚氯乙烯护套双绞屏蔽电缆，适用于一般数据的传输，传输距离较远，其绝缘电阻要优于RVSP能做到3000以上甚至几千兆欧。价格与RVSP差不多是一般用户优选型号。?第三种：RS485通讯电缆?结构：聚乙烯绝缘对绞铝塑膜分屏蔽带排流线，铝塑膜+镀锡编织总屏蔽带排流线聚氯乙烯护套双绞屏蔽电缆，适用于复杂的数据的传输，传输距离*远，效果*好的屏蔽双绞电缆，其绝缘电阻与RYVPS差不多。价格是屏蔽双绞电缆中*贵的。?产品规格：特性阻抗120欧姆，导体为24AWG多股绞合镀锡铜丝，PE绝缘护套；为适用于复杂的工业噪声环境，特采用铝箔/聚酯复合带100%屏蔽率+镀锡铜编制网90%屏蔽率共双重屏蔽，并附有独立TC接地导体，工业灰色PVC外护套。
