详细说明:
  0.6/1kV聚氯乙烯绝缘聚氯乙烯护套电力电缆
  0.6/1kV polyvinyl chloride(PVC)insulated and protective covered powercable
  (含普通型、阻燃型、耐火型)
  (Including conventional,flame-retardant and fire-resistant types)
  一、产品特点及用途  Features and applications
  聚氯乙烯绝缘聚氯乙烯护套电力电缆具有良好的电气性和化学稳定性,结果简单, 使用方便。本产品适用于交流额定电压U0/U为0.6/1kV及以下的输配电电线路上。
  阻燃电力电缆的主要特点是电缆不易着火或着火是延燃仅局限在一定范围内,适用于电缆敷设密集程度较高的发电站、地铁、隧道、高层建筑、大型工矿企业、油田、煤矿等场所。
  耐火电力电缆的主要特点是电缆除了能在正常的工作条件下传输电力外,电缆在着火燃烧时仍能保持一定时间的正常运行,适用于核电站、地铁、隧道、高层建筑等与防火安全和消防救生有关的地方。
  PVC insulated and protective covered power cable,whose electirc property and chemical stability are excellent,is simple in structure and convenient in application.This manufactu is applicable to the transmission and supply line,of which the AC rated voltage Uo/U iS 0.6/1kV or lower level.
  The flame-retardant power cable is not easily to catch fire and it can confine the fire in some limited area,therefore the cable is applicable to the places where the density of cable laying is high,such as generating station,subway,tunnel,high-rise building,large industrial and mining establishment,oil field,coal mine and so on.
  The fire-resistant power cable is ,beside the power transmission under normal condition,can continue operating normally for some time when it catches fire,so it is applicable to the places which is concerned to the fire protection such as nuke,subway,tunnel,high-rise building and so on.
  二、产品标准  Standards
  本产品按GB/T 12706.1-2008或IEC 60502标准组织生产,还可按用户要求的其它标准生产。
  阻燃型电缆除按上述标准外,其阻燃性能按GB/T 18380.3-2008或IEC 60332-3标准规定分成A、B、C、D四种不同的阻燃类别,A级类别的阻燃性能,用户可根据需要选用。
  耐火型电缆的耐火性能按GB/T 19216.21-2003生产。
  This manufacture is produced according to the standard GB/T 12706.1-2008 0r IEC 60502,and we can also manufacture it to meet your needs.
  The flame-retardant power cable,besides the foregoing standard,its fire retardant is divided in to4 types,A,B, C and D,according to the standard GB/T 18380.3-2008 0r IEC 60332-3,of which A performances best.You can adopt anyone to meet you need.
  The fire performance of the fire-resistant power cable is according to the standard GB/T 19216.21-2003.

  四、产品使用特性  0perating characteristics
  (1)额定电压U0/-U为0,6/lkV。 rated voltage Uo/U is 0.6/lkV
  (2)电缆导体的高额定温度为70℃。 maximum rated temperature of conductor is 70℃
  (3)短路时(长持续时间不超过5S)电缆导体的高温度不超过160℃。maximum temperature when in short circuit(no Ionger than 5s) is 160℃
  (4)电缆敷设时的环境温度应不低于0℃,其小弯曲半径如下:
  minimum surrounding temperature of cable laying is OoC,minimum bend radius is
  单芯电缆-20I(D+d),mm   singlecore cable-20(D+d),mm
  多芯电缆-15(D+d),mm   multicore cable-15(D+d),mm
  (D、d分别为电缆外径与主导体的标称直径,mm)
  (D and d are the external diameter ofcable and the nominal diameter ofconductor)
  五、主要技术参数  Technical parameters
  电缆载流量计算条件
  The condition of current carrying capacity account
  环境温度25℃  Surrounding temperatureis 25℃
  电缆导体工作温度70℃ Operating temperature of conductor is 70℃
  电缆埋地敷设时,土壤热阻系数g=1C.m/W,但尚未考虑电缆长期运行时由于水分迁移而导致土壤热阻系数升高 的现象。
  Soil thermal resistivity when Iaying the cable is g=l.0C.m/W (the rise of soil thermal resisitivtiy attribute to water migration when long operating is not taken into account.)
  电缆埋地敷设时,电缆的轴心与地面距离为1000mm。
  The distance between cable axes and the ground when laying the cable is lOOOm
  多跟电缆敷设时,电缆的轴心距离S=3D
  The distance between two cable axes is S=3D
