Problems solved by technology

[0002] With the grid company's recognition of carbon fiber composite wires, the promotion is gradually increasing, and the application of carbon fiber composite wires is getting wider and wider. The State Grid Corporation has higher and higher requirements for the toughness of the wires. Twisted composite conductors have been developed, but the related electric tension fittings can not fully meet the requirements of use, which limits the development of twisted composite conductors

Embodiment 1

[0023] See figure 1 , the smart grid stranded composite wire tension fittings in this embodiment include steel anchor 1, tension steel pipe 2, fixing screw 3, conductor lined aluminum pipe 4 and T-shaped tension aluminum pipe 5; tension steel pipe 2 It is a hollow structure, divided into an upper steel pipe and a lower steel pipe, which are fixedly connected by fixing screws 3; the steel anchor 1 and the tensile steel pipe 2 are an integrated structure; the upper steel pipe and / or the lower steel pipe are provided with glue injection holes 2-1. The inner surface of the upper steel pipe and the lower steel pipe is provided with a plurality of grooves 2-2 with one end connected to the glue injection hole 2-1. After the upper steel pipe and the lower steel pipe are fixed by the fixing screw 3, the groove 2-2 is used as the glue injection cavity . The inner diameter of the T-shaped tensile aluminum pipe 5 is larger than the inner diameter of the tensile steel pipe 2 . Both the c...

Abstract

The present invention discloses a stranded composite conductor tension metal fitting for a smart power network and an installation method thereof. The fitting comprises a steel anchor, a tension steel tube, a retaining screw, a conductor lining aluminum tube and a T-shaped tension aluminum tube. The tension steel tube is a hollow structure and is divided into an upper steel tube and a lower steel tube which are fixedly connected with each other through the retaining screw; the steel anchor and the tension steel tube are an integrated structure; and the upper steel tube and / or the lower steel tube are provided with resin injection holes. The steel anchor and the tension steel tube are combined into one body without the screw thread and the phenomenon that the screw threads are broken when the steel anchor is installed, and therefore, it is avoided that the metal fitting is scraped and damaged and there is no any damaging for the composite cores.

Description

technical field [0001] The invention relates to a strain-resistant metal fitting for a twisted composite wire used in a smart grid and an installation method thereof. Background technique [0002] With the grid company's recognition of carbon fiber composite wires, the promotion is gradually increasing, and the application of carbon fiber composite wires is getting wider and wider. The State Grid Corporation has higher and higher requirements for the toughness of the wires. Twisted composite wires have been developed, but the related electric tension fittings can not fully meet the requirements of use, which limits the development of twisted composite wires. Therefore, it is necessary to develop a tension fitting that is easy to install and does not damage the stranded composite core. Contents of the invention [0003] The first object of the present invention is to provide a strain-resistant fitting for stranded composite conductors for smart grids that is easy to instal...
