Thunder prevention dynamic protection limit puncturing cable clamp for air insulated lead

The utility model relates to a lightning-proof dynamic-protection limiting puncturing clamp for insulated overhead conductors. The lightning-proof dynamic-protection limiting puncturing clamp is characterized in that a main body of the puncturing clamp is a screwed rod; an internally-embedded wire groove is arranged inside the screwed rod; the bottom part of the wire groove is provided with a passivable sharp needles; a spiral pressing plate is nested outside the screwed rod; the lower surface of the spiral pressing plate is provided with a passivable sharp needles; a limiting conductive rod is arranged inside the wire groove; the screwed rod is connected with high voltage electrodes. The high voltage electrodes are respectively a dynamic protective main electrode and a dynamic protective auxiliary electrode; the high voltage electrodes correspond to the earthed electrodes; an insulation cover is arranged outside the screwed rod. With simple operation, convenient mounting and long service life, the lightning-
