Abstract

The invention discloses a copper-aluminum transition terminal of an Al-Fe-Mn-RE aluminum alloy cable, and belongs to the technical field of the copper-aluminum transition terminal. The copper-aluminum transition terminal of the Al-Fe-Mn-RE aluminum alloy cable comprises an aluminum alloy connecting pipe connected with a cable conductor and a copper nose connected with the other end of the aluminum alloy connecting pipe; a copper-aluminum transition part is arranged between the aluminum alloy connecting pipe and the copper nose; and the copper-aluminum transition part is an aluminum alloy in a columnar solid structure. The invention also provides a preparation method of the copper-aluminum transition terminal of the Al-Fe-Mn-RE aluminum alloy cable. The preparation method is simple, and easy to operate; and the prepared copper-aluminum transition terminal is excellent in electrical properties, mechanical properties and creep resistance, also has reliable connectivity under a condition of a constantly changing temperature, is outstanding in thermal stability and electric conductivity and can transit steadily and mildly from the aluminum alloy cable to the connecting pipe and to the copper nose.

Description

technical field [0001] The invention belongs to the technical field of copper-aluminum transition terminals, and relates to a copper-aluminum transition terminal for aluminum alloy cables, in particular to an Al-Fe-Mn-RE aluminum alloy cable copper-aluminum transition terminal and a preparation method thereof. The copper-aluminum transition terminal of the invention has excellent electrical properties, mechanical properties and creep resistance, reliable quality and no potential safety hazard. Background technique [0002] With the rapid development of my country's economic construction, the demand for electricity in various industries continues to increase, and the market space for the wire and cable industry is huge. However, copper and aluminum conductors, which are the main components in the wire and cable product structure, have their own shortcomings that are difficult to overcome, so it is necessary to design and manufacture copper-aluminum transition terminals.
