Abstract

The invention discloses a method for producing a bird damage resistant silicon fluoride insulated sleeve. The production method comprises the following steps: roller-milling a mixture formed by 10 to 30 percent of fluorine containing dimethyl polysiloxan, 40 to 50 percent of ethylene containing dimethyl polysiloxan, 20 to 40 percent of reinforcing filler silicon dioxide and electrical erosion resistant filler aluminum hydroxide, and 1 to 5 percent of dye in a banbury mixer at a temperature of between 70 and 120 DEG C and under a pressure of less than or equal to 0.2Mpa for 1 hour; adding 1 to 3 percent of vulcanizer in the mixture roller-milled by the banbury mixer and evenly mixing; roller-milling the mixture in a roller mixer for 1 hour, and then milling the mixture; re-milling the vulcanizer containing mixture milled by the roller mixer; rolling-extruding the mixture by an extrusion forming machine for forming; and finally, two-stage vulcanizing the mixture in a vulcanizing furnaceat a temperature of 180 DEG C for 2 hours to obtain the silicon fluoride insulated sleeve, cutting the silicon fluoride insulated sleeve into certain length, and sealing the tenon by a bonding agent when the sleeve is used. The invention is a method for producing a highly insulated bird damage resistant silicon fluoride insulated sleeve.

Description

technical field [0001] The invention relates to a fluorosilicone insulating sheath, in particular to a production method for a fluorosilicon insulating sheath used for preventing flashover and tripping of birds in high-voltage transmission lines. Background technique [0002] At present, power transmission and transformation lines have frequent tripping and blackout accidents caused by bird damage. In recent years, with the great development of the national electric power industry, the number of transmission lines has increased significantly. Bird damage tripping accidents in North China Power Grid and Northwest Power Grid have accounted for 8-12% of abnormal power outages, causing huge losses. The currently used technical measures such as anti-bird thorns and bird repellents cannot be completely solved, and potential hazards such as overlapping of foreign objects in complex living areas also require a high-insulation technical measure. Contents of the invention [0003] ...
