The color of the insulated wire is in accordance with the full chromatographic standard. Pair of insulated wires: two different colored insulated wires are twisted in pairs according to different pitch and are identified by a specified chromatographic combination. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs or more of cables plus 1% of the reserve pair. Core tape: wrap with a polygrease film tape. Shielding: the two sides are overlapped with or without corrugated metal strip, beyond the cable core of the longitudinal capsule. The plastic film coated on the surface of the shielding belt and the bonding sheath of the protective layer: black low density polyethylene. Hoisting line: the hoisting line is 7 strands of galvanized steel strand, nominal outside diameter is 6. 3 and 4 mm. The tensile strength of two types of 75mm is not less than 3000kg and 1800kg respectively. The suspension wire is coated with thermoplastic paint to prevent the steel wire from corrosion.

　　可靠接地时整个485线路的地线必须要有良好的接触，从而保证电压一致，因为在实际施工中，为了接线方便，将线剪成多段再连接，但是没有将屏蔽线作良好的连接，从而使得其地线分成了多段，电压不能保持一致，导致共模干扰。

同时，在安装的具体位置做明确的标注，安装施工方法的选择也应该做好充分而有详细的标注，所有的配电柜、变压器、配电设施等都需要合乎标准。在安装之前，对各种设备做好检测，只有符合要求才能付诸安装。电气设备的正常运转都靠各种仪表来确认，仪表的稳定性也是保障电气安装和运行质量的根本。所有的电气设备安装之后需要安装各种仪表，确保各种仪表达到国家技术标准。各种电气设备安装必须严格按照预先设计的图纸进行，对各种设备做好详细而又周密的检测，做好各方面的配套保护措施，充分保障各种电气设施不会外在干扰影响。

　　矿用阻燃通信电缆于2002年10月31日获煤矿产品安全标志证书，年多次扩大了安标产品的认证范围，MHYAV、MHYA32、MHYV、MHY32、MHYVP、MKVV、MKVV22、MKVV32等多种型号的产品均获得了安标证书。

　　HYA53/HYAT53（防鼠咬/直埋）主要用于传输音频、15市内通信电缆|通信电缆|（管道/架空）HYAC（架空 ）HYAT（防水）0kHZ及以下的模拟信号和2048kbit/s及以下的数字信号。在一定条件下，也可用于传输2048kbit/s以上的数字信号。

伺服电机使能后，PLC向伺服电机发送运行脉冲，伺服电机即可运行。针对伺服脉冲输入端口的接线方式，可以依照PLC侧输出端口的方式，进行如下处理：高速脉冲接线方式方式1，若PLC信号为差分方式输出，则可以使用方式1，其优点信号抗干扰能力强，可进行远距离传输。若驱动器与PLC之间的距离较远，则推荐使用此种方式。方式2，PLC侧采用漏型输出。日系PLC多采用此种方式接线，如三菱。方式3，PLC侧采用源型输出。

Flame-retardant Cables: ibec60332-3 / bs4066-3 flame-retardant grades (BunchedWires or Cables vertical Flame On BunchedWires/Cables) this is a beam cable. According to the test regulations, the 3.5m long cable samples are fixed with iron wire on the trapezoid frame, and the number of samples is determined according to the non-metallic materials required for different classification. The sample is hung vertically on the back wall of the furnace and air is introduced into the furnace through the inlet on the bottom plate. At 750 ℃ flame propane plane and the sample, the sample in the compulsory blowing (5 m3 / min air emissions, wind speed 0.9 m/s), must be in vertical combustion is not up to 20 minutes, cable within 2.5 meters flame spread out on its own. IEC60332 is divided into A, B, C and D to evaluate the flame retardant performance.



　　100对及以上线对的电缆加有1％的预备线对，但多不超过6对。缆芯内的间隙用石油膏填充。缆芯包带：用聚脂薄膜带绕包。屏蔽：用轧纹(或不轧纹)金属带，金属带纵包于缆芯包带之外。护套：黑色低密度聚乙烯。也可提供双层护套的电缆。

　　在使用RS485接口时，对于特定的传输线路，从RS485接口到负载其数据信号传输所允许的大电缆长度与信号传输的波特率成反比，这个长度数据主要是受信号失真及噪声等影响所影响。理论上，通信速率在100Kbps及以下时，RS485的长传输距离可达1200米，但在实际应用中传输的距离也因芯片及电缆的传输特性而所差异。

　　7）电缆外经:£18mm。在一定条件下，也可用于传输2048kbit/s以上的数字信号。适用于矿山、电厂、市内、近郊及局部地区。适合任何弱电安防工程使用。由于在芯线的外面包有一层铜丝屏蔽层，因此适合于在一些干扰比较大的地方使用，亦可用于对传输的信号要求严格的场合。
