产品结构及用途
铠装电缆增加的钢带可以认为它是机械保护层,以增加电缆的机械强度,提高防侵蚀能力,是为易受机械破坏及易受侵蚀的地区而设计的。可以采用任何一种方式敷设,更适用于岩石地区的直埋敷设。补充:说的通俗些铠装电缆也就是地埋的电力电缆,动力线传输电能。电缆加上铠装层的目的除了增强抗拉强度、抗压强度等机械保护延长使用寿命外,铠装的有一定的抗外力性能,还可以防止老鼠撕咬,不至于透过铠装造成电力传输问题,铠装的弯曲半径要大,铠装层可以接地保护电缆。
交联铠装电缆VV22、ZR-VV22和VV的用途是一样的,区别在于交联铠装电缆VV22、ZR-VV22多了一层钢带,在重量上就重一些。其他性能基本上是一样的,可参考VV技术参数。
VV22、ZR-VV22的适用范围:直埋敷设在地下,电缆能承受一定机械外力作用,但不能承受大的拉力。
