Description

technical field [0001] The invention relates to the technical field of electric power fittings processing equipment, in particular to a bending device for binding wires of insulators. Background technique [0002] In low-voltage and 10KV high-voltage overhead lines, insulators are generally used as cable supports. Most of the insulators used to insulate cables and towers are column insulators. [0003] Generally, when the cable and the post insulator are connected at the top of the tower, the cable is placed in the groove on the top of the post insulator, and then the cable and the post insulator are wound and bound with pre-twisted binding wires. [0004] Pre-twisted binding wires are generally made of at least two strands of metal wires connected in parallel and twisted in a helical structure. According to the cross-sectional size of the cable, the helical metal wire with a specified inner diameter is rotated in a helical direction to form a tubular cavity. The pre-twis...
