Abstract

The invention discloses a large-tonnage soft wire lift insulation tool and a manufacturing method thereof. The soft wire lift insulation tool comprises a soft pull rod and a connecting head. Both endsof the soft pull rod are annular. The soft pull rod comprises an inner core and a sheath coating the inner core. The inner core is formed by weaving 12 strands of PBO fiber or aramid fiber. The sheath is made of moisture-proof silk thread. The connecting head comprises a left side plate, a right side plate, a pulley and fixing members connecting and fixing the left side plate and the right side plate. The pulley is arranged between the left side plate and the right side plate. Each fixing member comprises a bolt and a nut. Three groups of fixing members are arranged. One group passes throughthe left side plate, the pulley and the right side plate. The large-tonnage soft wire lift insulation tool provided by the invention has excellent mechanical and electrical properties, and effectivelyprevents the cutting of a large-tonnage split rod.

Description

technical field [0001] The invention relates to a live working tool for extra-high voltage transmission lines, in particular to a large-tonnage soft wire-lifting insulating tool and a manufacturing method thereof. Background technique [0002] At present, the live work of ±1100kV DC UHV transmission line is used for the insulation load-bearing part of the large-tonnage wire-lifting tools and equipment, which generally adopts hard insulating tools, including insulating pull rods, pull rods, etc. Hard insulating tools have high strength and low elongation. However, the size and weight of hard insulated tools are large, and it is inconvenient to carry and transfer them in actual operations, and the labor intensity of the operators on the tower is high; while the mechanical strength of soft insulated tools such as insulated ropes and insulated ladders for live work is currently Low, large elongation, relatively small gap between line tower windows, too much elongation of the wir...
