Nanjing Electric began to develop composite insulators in the 1980s. It has strong technical research and development ability and team. The composite business department has advanced production equipment for composite insulators at home and abroad to ensure the product quality and meet the needs of customers. Among them, there are more than 20 sets of silica gel mixing equipment such as kneader, mixer, extruder, rubber filter, etc., and the theoretical annual production capacity of rubber compound is about 6000 tons; there are more than 20 sets of various rubber injection molding equipment such as 1100t, 550t, 500t, 330t, etc., and the annual production capacity of rod suspension composite insulator (equivalent to 110kV standard piece) can reach 1.3 million; It has more than 10 sets of imported 175 / 165 / 140 and other crimping production equipment, which fully meets the market demand of all kinds of composite insulators. In addition, there are nearly 50 sets of molding, extrusion, umbrella piercing, grading ring die-casting, bending, machining and other equipment, fully meeting the needs of various composite insulators and mass production orders. It is widely used in 10 kV - ± 800 kV projects in State Grid, South China Power Grid and overseas markets won the domestic and foreign customer's consistent high praise!
