Corrosion-resistant wind-vibration-resistant medium-strength aluminum alloy conductor aerial insulation cable production device and working method thereof

Abstract

The invention relates to a corrosion-resistant wind-vibration-resistant medium-strength aluminum alloy conductor aerial insulation cable production device and a working method thereof. According to anextrusion technological process, linear low-density polyethylene, carbon black masterbatches and an antioxidant are stirred and mixed in a mixing box, and then are mixed with a DCP catalyst added with an accurate weighing system via a gravitational dropping material weighing system, the mixture enters a barrel above a charging area of an extruding machine, and all materials in the barrel enter anextruder screw and are mixed uniformly. An aerial insulation able uses a medium-strength aluminum alloy conductor, compared with a traditional hard aluminum conductor, the medium-strength aluminum alloy conductor has the characteristics of excellent corrosion resistance and wind vibration resistance; by a semiconductor resistance water tape, the corrosion prevention property of the cable can be improved further; and the various component materials are accurately weighed and uniformly mixed, then the mixture is directly added in a peroxide crosslinking extruder and then is extruded out, any secondary processing courses do not exist, the production process is stable, and the obtained cable not only has excellent insulation and weather resistant properties, but also has characteristics of corrosion resistance and wind vibration resistance.

Description

technical field [0001] The invention relates to the field of cable materials and cable processing, in particular to a production device for overhead insulated cables with a corrosion-resistant and wind-resistant medium-strength aluminum alloy conductor and a working method thereof. Background technique [0002] Peroxide cross-linked polyethylene insulation materials are usually extruded and pelletized in the material production workshop. The processing of this material needs to be completed on two extruders. These processes not only increase the processing cost and the secondary transportation cost of raw materials, Moreover, the instability of material properties caused by the control of the production link has been increased. At present, a new equipment and process is developed to save material processing and transportation packaging costs, and at the same time simplify the material preparation process to the production site, which not only improves product quality, but al...
