Technical Field

[0001] The utility model relates to the technical field of high - voltage transmission lines, in particular to an insulator for a combined high - voltage transmission line with a fine - tuning structure. Background Technique

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding member, which can withstand voltage and mechanical stress. There are many types of insulators with various shapes. Although the structures and shapes of different types of insulators vary greatly, they are all composed of two major parts: an insulating part and a connecting fitting. An insulator is a special insulating control device that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles. Slowly, many disc - shaped insulators were hung at one end of the high - type high - voltage wire connection tower. It is used to increase the creepage distance and is usually made of glass or ceramic, and is called an insulator.

[0003] Currently, the existing insulators for 500 - 1000 kV high - voltage transmission lines are required to have a length greater than 4 meters. In this case, the diameter of the insulating rod will be greater than 110 mm and the weight will exceed 500 kg. There will also be insulating umbrella sleeves, flanges, connecting parts and other components installed on its surface. Thus, the weight and occupied volume of the device are relatively large, making it very difficult to transport the existing insulators, resulting in inconvenient transportation.
