Problems solved by technology
[0003] At present, the connection between wire conductors is generally carried out by bolt crimping of wire conductors through equipment clamps or copper wire lugs. In this connection method, the contact area of wire conductors is small, which is prone to poor contact problems. At the same time, the contact resistance is large. Easy to generate heat problems, resulting in reduced conductivity

The invention discloses a wire conductor connecting method which is used for connecting two wire conductors. The wire conductor connecting method is characterized by including the steps: enabling opposite ends of the two wire conductors to be inserted into a connecting pipe from two ends of the connecting pipe, and enabling the ends of the two wire conductors to contact; adjusting the lengths of the two wire conductors in the connecting pipe, and enabling the lengths of the two wire conductors inserted into the connecting pipe to be equal; uniformly filling the connecting pipe from gaps amongthe wire conductors and the connecting pipe with graphene. According to the method, the connecting pipe is filled with the graphene, the two wire conductors are connected through the filled graphene,corresponding detection is performed, joints of the two wire conductors are qualified, contact resistance of the joints of the wire conductors connected by the method is low, heating after power on isless, and the conductivity of the joints is effectively improved as compared with the prior art.
Description
technical field [0001] The present application relates to the technical field of electric wire conductor connection, in particular to a method for connecting electric wire conductors. Background technique [0002] With the rapid development of my country's power grid construction, the requirements for construction technology are getting higher and higher. During the construction of the power grid, the connection between wire conductors is a very critical step in the construction. The quality of wire conductor connection directly affects the quality of wire conductors. Electrical conductivity and heat resistance, thus affecting the reliability and safety of power transmission. [0003] At present, the connection between wire conductors is generally carried out by bolt crimping of wire conductors through equipment clamps or copper wire lugs. In this connection method, the contact area of wire conductors is small, which is prone to poor contact problems. At the same time, the ...
