Problems solved by technology

[0003] Due to the structure of the insulator with a layered insulating umbrella cover on the outside and the special environment used in high voltage, when the existing clamping device cannot clamp and fix the insulator, the clamping effect is not ideal, and it is easy to fall off and slide. At the same time, it has high potential safety hazards and cannot be applied to different types of insulators. Therefore, a new type of device for clamping insulators has become an urgent problem to be solved.

Description

technical field [0001] The invention belongs to the technical field of insulator clamping equipment, and in particular relates to a device for clamping insulators. Background technique [0002] An insulator is a device installed between conductors of different potentials or between conductors and ground potential components. It can withstand voltage and mechanical stress. It is a special insulation control that can play an important role in overhead transmission lines. Early During the years, insulators were mostly used on utility poles, and gradually developed into high-voltage wire connection towers where many disk-shaped insulators were hung at one end, called insulating umbrella covers, which were used to increase the creepage distance and were usually made of glass or ceramics; [0003] Due to the structure of the insulator with a layered insulating umbrella cover on the outside and the special environment used in high voltage, when the existing clamping device cannot c...
