ID卡和ID卡读卡器的性能价格比和感应距离要好于IC卡和IC卡读卡器。如果只是用于门禁和考勤或者停车场一卡通，建议使用ID卡读卡器和感应卡。如果需要兼容非定额消费一卡通就只能采用IC卡读卡器和感应卡了。ID卡市面比较流行且性价比好的是EM卡。注意事项三:不要单从外观来判断国产读卡器的质量。国内读卡器大多采用公共模具，或者抄袭国外读卡器外型。模具是大家通用的，谁都可以买到外壳，所以即使同一外型的读卡器可能产自不同的厂家，服务和质量也是不一样的。

　　 6KV及以上电缆接头： ①安装电缆终端头时，必须剥除半导体电屏蔽层，操作时不得损伤绝缘，应避免刀痕凹凸不平的情况，必要时用砂纸磨平；屏蔽端部应平整，并要把石墨层（碳粒）清除干净。②塑料绝缘电缆端头铜带屏蔽和钢铠必须良好接地，对短路也遵循这项原则，避免三相不平衡运行时钢铠端部产生感应电动势，甚至“打火”及燃烧护套等事故。
