詳細說明:
  0.6/1kV聚氯乙烯絕緣聚氯乙烯護套電力電纜
  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、產品特點及用途  Features and applications
  聚氯乙烯絕緣聚氯乙烯護套電力電纜具有良好的電氣性和化學穩定性,結果簡單, 使用方便。本產品適用于交流額定電壓U0/U為0.6/1kV及以下的輸配電電線路上。
  阻燃電力電纜的主要特點是電纜不易著火或著火是延燃僅局限在一定范圍內,適用于電纜敷設密集程度較高的發電站、地鐵、隧道、高層建筑、大型工礦企業、油田、煤礦等場所。
  耐火電力電纜的主要特點是電纜除了能在正常的工作條件下傳輸電力外,電纜在著火燃燒時仍能保持一定時間的正常運行,適用于核電站、地鐵、隧道、高層建筑等與防火安全和消防救生有關的地方。
  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、產品標準  Standards
  本產品按GB/T 12706.1-2008或IEC 60502標準組織生產,還可按用戶要求的其它標準生產。
  阻燃型電纜除按上述標準外,其阻燃性能按GB/T 18380.3-2008或IEC 60332-3標準規定分成A、B、C、D四種不同的阻燃類別,A級類別的阻燃性能,用戶可根據需要選用。
  耐火型電纜的耐火性能按GB/T 19216.21-2003生產。
  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.
  三、產品型號  Types of products
  普通型電纜型號  * Conventional type
  VV-銅芯聚氯乙烯絕緣聚氯乙烯護套電力電纜
  VV -copper core,PVC insulated and protective covered power cable
  VV22-銅芯聚氯乙烯絕緣鋼帶鎧裝聚氯乙烯護套電力電纜
  VV22 -copper core,armored,PVC insulated and protective covered power cable
  阻燃型電纜型號  * Flame-retardant type
  在普通型號電力電纜型號前加Z (A.B.C.D)
  Add Z(A.B.C.D)before the conventional types
  耐火型電纜型號  * Fire-resistant types type
  在普通型電力電纜型號前加N  Add N before the conventional types
  四、產品使用特性  0perating characteristics
  (1)額定電壓U0/-U為0,6/lkV。 rated voltage Uo/U is 0.6/lkV
  (2)電纜導體的高額定溫度為70℃。 maximum rated temperature of conductor is 70℃
  (3)短路時(長持續時間不超過5S)電纜導體的高溫度不超過160℃。maximum temperature when in short circuit(no Ionger than 5s) is 160℃
  (4)電纜敷設時的環境溫度應不低于0℃,其小彎曲半徑如下:
  minimum surrounding temperature of cable laying is OoC,minimum bend radius is
  單芯電纜-20I(D+d),mm   singlecore cable-20(D+d),mm
  多芯電纜-15(D+d),mm   multicore cable-15(D+d),mm
  (D、d分別為電纜外徑與主導體的標稱直徑,mm)
  (D and d are the external diameter ofcable and the nominal diameter ofconductor)
  五、主要技術參數  Technical parameters
  電纜載流量計算條件
  The condition of current carrying capacity account
  環境溫度25℃  Surrounding temperatureis 25℃
  電纜導體工作溫度70℃ Operating temperature of conductor is 70℃
  電纜埋地敷設時,土壤熱阻系數g=1C.m/W,但尚未考慮電纜長期運行時由于水分遷移而導致土壤熱阻系數升高 的現象。
  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.)
  電纜埋地敷設時,電纜的軸心與地面距離為1000mm。
  The distance between cable axes and the ground when laying the cable is lOOOm
  多跟電纜敷設時,電纜的軸心距離S=3D
  The distance between two cable axes is S=3D
  VV  Z(A.B.C.D)-VV   N-VV   0.6/1
