The invention provides a full-tension splice strip winding device and relates to the field of electric power fittings, A full tension splice strip winding device comprises: The winding mechanism is provided with a hook piece, one end of the winding mechanism away from the hook piece is connected with the handle, the hook piece is used for hooking the full-tension connecting strip, and the handle is used for driving the winding mechanism to rotate relative to the broken wire strand so that the full-tension connecting strip inside the hook piece is wound to the broken wire strand. The technicianwinds the full-tension splice strip onto the conductor by adopting the full-tension splice strip winding device, which is more compact and tighter with the conductor and better in winding quality than the free-hand winding device; The winding speed of the full tension splice winding device is faster than that of the bare-handed winding, so the labor of the technicians can be greatly reduced.
