Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wire spacer plate, concretely to a double split type spacer. BACKGROUND

[0002] The core function of the spacer used in the bundled conductor of the power transmission line is to effectively constrain the relative displacement between the sub-conductors and ensure that the bundled conductor maintains its established geometric configuration under normal operating conditions. For power transmission lines in China with voltage levels of 550KV and below, depending on the number of bundled conductors, the wire spacer is currently divided into three specialized types suitable for two, three, and four bundled conductors. Further, according to the working performance characteristics of the spacer, they can be broadly classified into two categories: one is the spacer with damping effect, and the other is the non-damping type spacer. However, the current market design of wire spacers is generally basic and has several shortcomings. Specifically, the installation process of the clamping components on these spacers is relatively complex and inefficient. More critically, due to the fixed type of the spacer, it lacks flexibility and cannot meet the diverse spacing needs of different bundled conductors in actual applications. Therefore, there is still room for improvement in the design and improvement of wire spacers to adapt to more complex and variable power transmission line configuration requirements. To address the above issues, there may be existing technical means in the prior art to solve the problem, but this case wants to provide an alternative or replacement technical solution. SUMMARY
