架空绝缘导线金具
Overhead Insulated Wire Fittings

FH 系列架空导线防雷线夹

FH series overhead wire lightning protection clamp

原理与特点 /Principle and Features
将该金具安装在线路绝缘子附近的架空导线上，当雷电过电压超过一定数值时，在防雷金具的穿刺电极引弧
臂和接地电极之间引起闪络，形成短路通道，接续的工频电弧移到线夹的燃弧臂上燃烧，释放过电压能量，
以保护导线和绝缘子免于烧伤。
我公司研发的防雷金具系列，特别是10~20kV绝缘导线用穿刺型，由于采用了独特的穿刺齿结构和电极设计，
不但安装方便，电气连接更为可靠，且不伤导线。通过武汉高压研究院的测试，深受广大用户的好评。
When the lightning overvoltage exceeds a certain value, flashover occurs between the puncture electrode
arm of the lightning protection device and the ground electrode to form a short-circuit channel, and a
continuous power-frequency arc is formed on the overhead conductor near the line insulator. Moving to
the burning arm of the clip to burn, release the over-voltage energy to protect the wire and insulator from
burns.
My company developed a series of mine with gold, especially the 10~20kV insulated wire puncture type,
the use of a unique puncture tooth structure and electrode design, not only easy to install, more reliable
electrical connections, and do not hurt the wire. Through the Wuhan High Voltage Research Institute of
the test, praised by the majority of users.
