[0002] With the continuous development of the national communication and electric power industry, more and more requirements are put forward for sag and tensile strength in the laying of long-span overhead cables. There are various strengths. The pre-twisted wire used in the prior art is pre-formed. A single type of pre-twisted wire cannot be applied to all cables with outer diameters or cables with all tensile strengths. It needs to be known in advance during construction or maintenance. The outer diameter and tensile strength of all the cables required on the construction site, so that the matching pre-twisted wires are carried, and the applicable ones are selected during construction, which brings inconvenience to the construction

Abstract
The invention belongs to the field of cables, and particularly relates to a stranding device of a strain fitting stranded wire which is provided with a box body, the upper end of the box body is connected with a cover body, and the stranding device is characterized in that a first bracket, a pay-off rack and a second bracket are arranged in the box body, and a driven gear is arranged in the firstbracket; a plurality of through twisting holes are formed in the driven gear body around the circle center of the driven gear body, and a cable clamping device is arranged in the driven gear body. Thedriven gear is meshed with a driving gear on one side of the box body; the left end of the box body is connected with a direction correcting part; according to the invention, the problem that a single type of pre-twisted wire cannot be matched with all external diameter cables in the prior art is solved; the device has the beneficial effects of being convenient to use, improving the constructionefficiency, saving the construction time, freely adjusting the twisting intercept, the twisting length and the twisting number of the twisted wires and the like.
