The utility model discloses a parallelly connected interstitial structure of 35kV electric line insulator is exclusively used in, the zuo banzhi that beckons on, the arc angle to be arranged by bilateral symmetry including last arc angle and the lower arc angle of ing goes up and beckons the arc angle and half on the right side to go up the trick arc angle to constitute, and lower arc angle comprises lower the arc angle of zuobanzhi and half right lower arc angle that bilateral symmetry arranged, go up and beckon arc angle and lower arc angle to connect in parallel respectively in insulator chain's both ends, go up to beckon the arc angle tip to the insulator chain central line be 400mm apart from XC, lower arc angle tip is 450mm to the insulator chain central line apart from XP beckons arc angle short circuit insulator chain's high YC to be 50mm on, lower arc angle short circuit insulator chain's high YP is 73mm. Parallelly connected clearance based on under this structural parameters can prevent effectively that the insulator chain on the 35KV transmission line is struck by lightning.
