Abstract
The invention discloses a stranded composite core strain fitting for a smart power grid and a connection method for the stranded composite core strain fitting. The strain fitting comprises a composite core lining flexible aluminum tube, a strain steel tube, a strain steel anchor, a conductor lining aluminum tube and a T-shaped strain aluminum tube, wherein the composite core lining flexible aluminum tube is a fully-annealed flexible aluminum tube; the strength of the flexible aluminum tube is 50-80MPa; and the thickness is 1.0-5.0mm. The fully-annealed flexible aluminum tube is adopted as the composite core lining aluminum tube, so that, on one hand, flexible aluminum is in direct contact with a composite core in the crimping process, direct contact of the composite core and the steel tube is avoided and the carbon fiber-reinforced composite core is not damaged; and on the other hand, the flexible aluminum infiltrates the inside of a composite core stranding layer in a crimping manner and the grip force of the composite core and the fitting is improved.
