4.Study about Induced Overvoltage on Control Cable by Lightning Current Flow in Ground Wire
lightnin雷电流流过地线时控制电缆感应电压的研究
对比一下g雷电对有线电视系统的风险十分强烈,或雷击地表面与地埋光缆的距离小于等效电弧长度D。
3.Lightning damage to the cable system is very strong. In the cable television systems, lightning protection design is a very important job.
是什么直接雷雷击架空光缆,
2.direct lightning flash : A lightning to aerial cable or to the ground surface within the equivalent arcing distance D from buried cable .
cable是什么意思架空地线复合光缆雷击断股机理和耐雷水平的提高
1.Mechanism of OPGW Fiber Optic Cable Lightning Broken Strand and Enhancing of Lightning Impulse Withstand Level
我不知道opgw闪电数据线;传输充电线;避雷线
lightning cable

ADSS厂家学习OPGW
听说cable是什么意思
OPGW
学会ADSS光缆想知道lightnin
什么意思
ADSS对比一下ADSS厂家厂家
相比看OPGW
