Self-supporting full-plastic cable (HYAC) : self-supporting full-plastic cable has two kinds of concentric structure and calabash structure. The commonly used HYAC full-plastic cable is calabash structure. Wire: annealed bare copper wire with diameter of, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9; Color the insulation line according to the full chromatographic standard. A single insulated wire is twisted in pairs at different pitch to minimize crosstalk and a specified chromatographic combination is used to identify pairs of wires. Cable core: the cable core structure is based on 25 pairs of cables. More than 25 pairs of cables are assembled according to the unit. Each unit is wrapped with the unit of specified chromatogram to identify different units. More than 100 pairs of cables plus 1% of the reserve pair. Shielding: the shielding layer is made of corrugated metal tape which is wrapped vertically on the outside of the cable core wrap belt and firmly bonded on both sides. The metal strip of the shielding layer is coated with plastic film to facilitate bonding with the sheath to prevent corrosion of the shielding layer. Protective sleeve: protective sleeve is black low density polyethylene, can use double protective sleeve according to the need.

功能所示为串阻减压起动和反接制动电气控制线路,主电路中合上QF后,当主触头KM1,KM3闭合,则电动机串联了电阻R开始减压起动,到达稳定转速后,主触头KM3断开,电动机切换为正常运转状态。制动时主触头KM1断开,KM2闭合,电动机转子施加制动反转转矩,电动机接近零转速时,主触头KM2断开,撤去制动反转转矩,电动机停转。:减压起动与反接制动分析所示为plc替代控制的主电路,与继电器接触器控制时的主电路基本保持不变,为PLC提供电源的两路线则采用变压器输出。

  2.2 电缆型式由系列代号、绝缘、护套材料代号、外护层和性能特征代号5个部分组成。产品执行GB国家标准。其中屏蔽型控制电缆,由于具有良好的评比性能得到电厂、电站的大量使用,电缆意义敷设在市内、电缆沟、管道、直埋、竖井等能承受较大机械拉里的固定场合。

  特别适用于精密电子装置场所,如智能大厦、计算机中心和航空航天监控中心等。低环境温度:固定敷设不低于-60℃;聚氯乙烯护套电缆不低于-40℃。2.电缆安装敷设温度应不低于0℃(氟塑料、硅橡胶、丁腈护套电缆不低于-25℃)。

  矿用通信电缆2、绝缘材料:高密度聚乙烯或聚丙烯,按照全色谱标准标明绝缘线的颜色。3、绝缘线对:把二根不同颜色的绝缘线按不同的节距扭绞成对,并采用规定的色谱组合以便识别线对。4、通信电缆缆芯结构:以1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。

建立项目部新的材料台账。库房管理上项目部自行建立了材料电子台账,目的就是为了更好的管理材料。电子台账主要由“办公用品台账、电气材料台账,水暖材料台账,工具台账,临水材料台账,临电材料台账”组成。并且每月清点库存,做到帐物相符。项目工期紧,施工单位人员及技术力量不足,时间紧,工作量大。同时针对分包班组施工速度冗慢,人员配备不足,工期拖延施工质量差问题,同分包负责人协商,增加大工数量及严格要求施工质量,落实各项施工方案,加班加点,并且积极协调各施工单位之间相互关系,化解施工中出现的问题。
