电力电缆线芯线芯是电力电缆的导电部分,用来输送电能,是电力电缆的主要部分。电力电缆绝缘层绝缘层是将线芯与大地以及不同相的线芯间在电气上彼此隔离,保证电能输送,是电力电缆结构中不可缺少的组成部分。电力电缆屏蔽层15KV及以上的电力电缆一般都有导体屏蔽层和绝缘屏蔽层。
况且,房梁、立柱上是不能开孔、开槽的,因此在顶部走管的过程中,所遇到的每一个立柱、房梁,都需要将管引下来从地面或墙面走管,大大增加了管材用量。坏处费用增加耗材的费用只是一方面,更重要的是人工费用。与传统的地面走管施工速度比起来,顶部走管要慢不少——不仅慢,还很累。一般传统施工方式5天可以做完的工程,用顶部走管的方式,可能需要7天甚至10天(横梁、立柱的数量越多,耗费的时间也就越多)。在这里提醒打算顶部走管的朋友一下,横梁和立柱是顶部走管大的困难,如果家里的立柱或横梁数量较多,不建议使用顶部走管的方法——一定不能在衡量或立柱上开孔、开槽。

This product is suitable for communication lines in urban, suburban and local areas. Conductive core wire adopts soft copper wire with nominal diameter of 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9mm. Twisted into the single wire insulation after the heart type (10, 20) or the unit type twisted into core (30 to and above), each basic unit of the unit with same color, the basic unit of cable tie color arrangement according to the re of the chromatography. On the surface of the cable core, a non-hygroscopic polyester belt or a non-woven cloth belt is used to wrap the cable core and then add the longitudinal package of the moisture-proof metal shield belt. The outer sheath can be made into polyurethane or chlorine sheath. The self-supporting cable is to squeeze the cable core and steel strand parallel to the same "8-character" calabash outer sheath. ?
Class A system - any phase conductor of such A system can be separated from the system within 1min when it comes into contact with ground or ground conductors. B class system, the system includes only the single-phase earth fault short-time running conditions, earth fault time should be no more than 1 h, but in any case, the longest do not exceed 8 h, ground fault total duration of not more than 125 h every year; Class C systems -- systems that do not belong to class A and class B.

剩下不亮的全是地线。简单的,拿个220V的灯泡,用电笔确定火线后,分别用两条线和火线接在灯头上,从亮度上就可以区别零线和地线,亮的是零线,稍暗的是地线。用万用表。将万用表置于交流档500v,手捏一表笔,另一表笔分别触接电源线,有电压高的是火线,低的是零线,电压为0的是地线。零线对地电阻小于4欧为可靠接地。用万用表置于交流档地250v测火线与零线、火线与地线的压差,两值相差在5v以下为可靠接地。关于火线和零线的区别,普通的家用照明电路中,火线跟大地之间存在220V的电压,零线跟大地之间没有电压(或说电压为0),因此火线跟零线之间也就存在220V的电压。
Flame retardant cables and fireproof cables: the difference between the average person is very easy to confuse the concept of flame retardant cables and fireproof cables, although there are many more flame retardant cable applies to the advantages of chemical enterprise, such as low, low smoke, non-halogen, but in general, fire-resistant cable can replace flame retardant cable, and flame retardant cables can't take place of fire-resistant cable.
额定电压:300V/300V 低烟无卤电缆低烟无卤电缆,是指不含卤素(F、Cl、Br、I、At)、不含铅镉铬汞等环境物质的胶料制成,燃烧时不会发出有毒烟雾的环保型电缆。电缆的无卤低烟、低卤低烟特性,当火灾发生时,蔓延速度慢,烟浓度低,可见度高,有害气体释放量小,便于人员撤离。
