arc-protection hardware

After following up the effect of the arc-protection hardware with post insulator for one year,the resultes show that the arc-protecion hardware with post insulator could increase the lightning-withstand level of the 10kV overhead insulation-covered conductors to prevent lightning-caused breaking.
对穿刺型防弧金具配合防雷支柱绝缘子在实际运行线路中试用效果经过一年的跟踪考察,结果表明装设穿刺型防弧金具配合防雷支柱绝缘子能有效提高10kV架空绝缘线路的耐雷性能,防止绝缘导线雷击断线的发生。
