The utility model provides five-section double-hanging-point strain insulator strings. Strain insulator strings formed by composite insulators which are connected in series are arranged in five sections. Two ends of each strain insulator string are connected with a support and a strain clamp. Two ends of the five-section strain insulator strings are provided with a first three-to-two link plate and a second three-to-two link plate respectively. A second U-shaped hanging ring, a first ZBD type right-angled hanging plate, a first triangular link plate and a third parallel hanging plate are sequentially arranged between on ends of two stain insulator strings on the two sides and the first three-to-two link plate, while a second triangular link plate and a fourth parallel hanging plate are sequentially arranged between the other ends of the two strain insulator strings on the two sides and the second three-to-two link plate. Compared with the prior art, the five-section double-hanging-point strain insulator strings are made by using mature processing process, so that the structural strength of an armor clamp and the strength of an armor clamp string are easily guaranteed; through the optimization of the size of the armor clamp structures, connecting methods and the quantity of insulators, the structural strength of the strain insulator strings can be effectively improved, so that wires can be dragged and fixed to a tension support, and the normal operation of a power transmission line is ensured.
