Problems solved by technology
The problem of forming the existing technology is: or invest a lot of money to make more grades of different creepage distances, or special "molding molds" for sheath sheds, to avoid the waste of rubber caused by redundant creepage distances as much as possible, but This requires a lot of investment, and even some "forming dies" have a very low utilization rate, resulting in a waste of investment; or limited production of "forming dies" that form a sheath shed with a small amount of fixed creepage, however, it is inevitable to cause redundant A large amount of rubber waste caused by creepage distance

The invention relates to a partition type compound insulator with jacket umbrella skirt sets different in creeping distance, a preparation mould and a preparation method thereof. The partition type compound insulator provided by the invention comprises a core bar, an end part component and a jacket umbrella skirt part, wherein the jacket umbrella skirt part is integrally arranged on the core bar in an injection molding form; the jacket umbrella skirt part comprises at least two constant creeping distance value jacket umbrella skirt distributing areas with different creeping distances; and each of the constant creeping distance value jacket umbrella skirt distributing areas comprises constant creeping distance value jacket umbrella skirt sets same in the creeping distance and positioning jacket umbrella skirt sets located at two ends of the constant creeping distance value jacket umbrella skirt sets. The invention also provides the preparation mould of the partition type compound insulator and the preparation method for preparing the partition type compound insulator. The partition type compound insulator has the beneficial effects that the optimized combination is performed according to different creeping distance demands and the cost is greatly lowered.
Description
technical field [0001] The present invention relates to the technical field of power transmission and transformation, in particular to a partitioned composite insulator with shed shed groups with different creepage distances for overhead transmission lines with a rated voltage higher than 10kV in the field of power transmission and transformation technology, and a mold for its preparation. Preparation. Background technique [0002] The key to the quality of composite insulator products is the safety and reliability of electrical insulation performance and mechanical performance. The shape and structure of the sheath shed that constitutes the outer insulation of composite insulator products (that is, the cross-sectional shape of the insulator) is an important parameter to ensure electrical insulation performance, and should comply with relevant domestic and foreign standards. [0003] At present, the existing technology of making long rod-shaped composite insulator strings b...
