Test electric long narrow flag experimental apparatus

The utility model relates to a test electric long narrow flag experimental apparatus, installation electrification by friction ware sets up a transverse slipway at the insulation board front end on the base of insulation board side, sets gradually sinusoidal wave slide, sawtooth wave slide, rectangle slide and circular slide on the insulation board of this transverse slipway rear side from left to right, and this sine wave slide, sawtooth wave slide, rectangle slide and circular slide pass through cambered way and horizontal slide rail connected, slide to inlay in the transverse slipway and adorn a plurality of bench insulators of testing electric long narrow flag. The utility model discloses in, the electric charge is produced by motor drive's electrification by friction machine, and is fast, save the operating procedure, and student's accessible cambered way makes the copper mesh produce different shapes in sliding all bench insulators to the slide of every specific shape to the sled of observing cable unde
