湖北省电力软电缆VVR
电力电缆:用于传输和分配电能的电缆。常用于城市地下电网、发电站的引出线路、工矿企业的内部供电及过江、过海的水下输电线。在电力线路中,电缆所占的比重正逐渐。电力电缆是在电力的主于线路中用以传输和分配大功率电能的电缆产品,其中包括1-500KV以及以上各种电压等级,各种绝缘的电力电缆。VV电缆 电力电缆VV

电力电缆的基本结构:由线芯(导体)、绝缘层、屏蔽层和保护层四部分组成。 VV电缆 电力电缆VV
(1)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。
(2)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。
(3)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,保证电能输送,是电力电缆结构中不可缺少的组成部分。
(4)保护层 保护层的作用是保护电力电缆免受外界杂质和水分的侵入,以及防止外力直接损坏电力电缆。
