Description

technical field

[0001] The invention belongs to the technical field of cable crimping, in particular to a crimping device for aluminum-steel-cored wires. Background technique

[0002] Steel-cored aluminum stranded wire is made of aluminum wire and steel wire, which is suitable for overhead transmission lines. It has a steel "core" inside, and aluminum wires are wound around the steel core by twisting on the outside; the steel core It mainly plays the role of increasing the strength. The aluminum stranded wire mainly plays the role of transmitting electric energy. During the crimping operation, one end of the stranded wire needs to be inserted into the crimping tube and crimped to complete the connection and use, which is convenient for multi-wire connection or protective installation of the joint. .

[0003] After retrieval, the Chinese patent authorization number is CN201320769786.4, which discloses a crimping device for aluminum-steel conductors for power conductor constr...
