The utility model discloses a restrain alternate conductor spacer that two -circuit transmission line deiced jump. Alternate conductor spacer comprises shock absorbing means, a connecting device and the 2nd connecting device, shock absorbing means is connected with double -phase power transmission line through a connecting device and the 2nd connecting device respectively, a connecting device comprises link plate, insulator and fully adjustable's hydraulic damper, insulator one end warp hydraulic damper connects shock absorbing means, its other end warp the link plate is connected with the power transmission line. The arrangement method including set for alternate conductor spacer length and control range, oscillator number and steps such as model, the alternate conductor spacer mounted position of settlement and number are inhaled in the selection. Alternate conductor spacer can self -adaptive control length, reduces the change of wire shape and the conductor spacer load with conductor jointing department, improvement circuit life. It is through hollow structure, and at the on the premise of of not gaining in weight, the slenderness ratio of minimize conductor spacer improves the resistance to compression dough stability of conductor spacer.
