Oil filled telecommunication cable main electrical properties: 1. The oil filled cable dc resistance: 20 ℃, 0.4 148 0.5 or less & have spent 2. Insulation electric strength of oil-filled cable: 1min between conductors 1kv does not break the conductor and shield 1min& NBSP; 3 kv no breakdown 3. Oil-filled cable insulation resistance: each conductor and the rest of the grounding wire core, the HYAT cable is more than 3000 m Ω. Km. 4. Working capacitance of oil-filled cable: average value: 52 + / -2nf /km 5
Local cable USES manufacuring HYA, HYAT, HYAC, HYPAT, HYPA and HYA53 HYAT53, HYPA53 HYPAT53 type cable is designed for main telephone switching area, relay telephone cable, manufacuring HYA, HYAT, HYPA and HYPAT is mainly used for pipe laying, also can be used for overhead, but need to disconnect; HYAC only applies to overhead, no need for suspension lines or hooks; The HYA53, HYPA53, and HYPAT53 cables provide the mechanical strength and corrosion resistance of the cables. They can be laid in any way, which is more suitable for direct burial in rock areas. The operating temperature is -30 ~60 degrees.

交流接触器尤其是电磁式接触器,是我们电工工作中极为常见常用的一种电气控制器件。至于其工作原理和结构特点,相信广大同行们都是相当熟悉。可大家在使用过程中,不知注意到一种现象没有——在触点容量低于60A的交流接触器中,其吸合线圈工作电源多直接使用交流电源(多见AC380V、220V、36V三种电压等级);而一旦接触器触点容量高于60A后,其吸合线圈工作电源则多变成直流形式(虽然也是引入交流电源但已经经过整流电路转换)。

  低烟无卤电线特性:低烟无卤电缆(1)抗张强度比一般PVC电线大:一般PVC电线抗张强度大于1.05Kgf/mm2,而低烟无卤电线抗张强度大于1.2Kgf/mm2;(2)具有良好的耐候性(-30℃~105℃);(3)具备良好的柔软度(硬度为80—90);(4)具有非移性(因为此产品配方中不用添加可塑剂。
