电力电缆 VV
交联聚乙烯绝缘电力电缆是采用化学方法或物理方法,使聚乙烯分子由线型分子结构转变为三维网状结构,由热塑性的聚乙烯变成热固性的交联聚乙烯,从而提高了聚乙烯的耐老化性能、机械性能和耐环境能力,并保持了优良的电气性能。
交联聚乙烯绝缘电力电缆导体的允许长期最高温为90摄氏度,较低绝缘电缆、聚氯乙烯绝缘电缆和聚乙烯绝缘电缆高,且具有重量轻、结构简单、使用方便、耐化学腐蚀和敷设不受落差限制等优点。
26/35KV电力电缆,18/30KV交联电缆,12/20KVYJV电缆,8.7/15KVYJV22电缆线,6/10KV铝芯交联电缆线,3.6/6KVYJLV单芯电缆
中低压交联电缆产品标准 Standard
本产品按GB12706《额定电压35V及以下铜芯、铝芯塑料绝缘电力电缆》标准生产,同时还可根据用户需要按国际电工委员会推荐标准IEC、英国标准、德国标准及美国标准生产。
The product is manufactured according to the standard of《GB12706 or IEC、BS、DIN and ICEA upon request.
适用范围 Applications
本产品适用于工频额定电压3.6/6kv~26/35kv输配电线路作配送电能子用。
The product is suitable for use in power transmission and distribution lines with rated power frequency voltage 3.6/6kv~26/35kv.
使用特性 Operating characteristics
· 工频额定电压U0/U为3.6/6kv~26/35kv。
Rated power-frepuency voltage U0/U: 3.6/6kv~26/35kv.
· 电缆导体的最高允许工作温度:90℃。
Max.admissible operating temperature of the conductor:90℃.
· 短路时(最长时间不超过5s)电缆导体的最高温度不超过2500C。
Max. short-circurt temperature of conductor shall not exceed 2500C.
(5s maximum duration)
· 电缆敷设时环境温度应不低于00C。
The ambient temperature under installation should not below 00C.
· 电缆弯曲半径:三芯电缆不小于电缆外径15倍;单芯电缆不小于电缆外径20倍。
The bending radius of a single-core cable should not less than 20 times of the cable diameter.
The bending radius of a single-core cable should not less than 15 times of the cable diameter.
电缆额定电压的选择 Voltage designation
· 电缆的额定电压应适合于电缆系统的运行状况,用U0/U(Um)kv表示。
U0-电缆设计用的导体对地或金属屏蔽之间的额定工频电压;
U-电缆设计用的导体间的额定工频电压;
Um-设备可承受的“最高系统电压”的最大值。
The rated voltage of the cable for a given applixation shall be suitable for the operating conditions
in the system in which the cable is used,and is expressed in the form of U0/U(Um)kv
wher:
U0-The rated power-frequency voltage between conductors and earth metallic screen ,for which the cable designed;
U - The rated power-frequency voltage between conductos, for which the cable designed;
Um- The maximum value of the“highest system voltage”for which the equipment may beused.
· 三相系统用电缆的U0值推荐如下表:
