The invention relates to a double-bearing double-guide rigid short dropper for a subway, which is connected between two carrier cables and two contact lines, and is provided with a contact line dropper wire clamp fixedly connected with two contact lines. A nylon protective sleeve is fixed on the carrier cable; carrier cable dropper wire clamps are fixedly connected to the portions, located on thetwo sides of the nylon protective sleeve, of the carrier cable respectively; a connecting steel wire is connected between the contact line dropper wire clamp and the nylon protective sleeve, and an electric connection jumper wire for achieving current carrying of the whole dropper is connected between one of the carrier cable dropper wire clamps and the contact line dropper wire clamp. The nylon protective sleeve is arranged on the carrier cable, a clamping state is kept between the nylon protective sleeve and the carrier cable, so that the position of the connecting steel wire is kept unchanged when the connecting steel wire is subjected to lifting force, the connecting steel wire and the carrier cable are insulated, use in a space with a small distance between the carrier cable and the contact line can thus be met, and the stability and the safety of contact network power transmission are improved.

    本发明涉及一种地铁用双承双导刚性短吊弦,连接在两根承力索与两根接触线之间,具有固连两根接触线的接触线吊弦线夹,所述的承力索上固定有尼龙保护套,位于尼龙保护套两侧的承力索上分别固连有承力索吊弦线夹,所述接触线吊弦线夹和尼龙保护套之间连接有连接钢丝,承力索吊弦线夹之一与接触线吊弦线夹之间连接有实现吊弦整体达到载流的电连接跳线。本发明在承力索上安装尼龙保护套,且使其与承力索之间保持夹紧状态,以此确保连接钢丝在受到抬升力时保持位置不变,同时可使连接钢丝与承力索之间保持绝缘,从而可满足在承力索与接触线间距较小的空间使用,提高接触网电力传输的稳定性和安全性。
