Description

Technical Field

[0001] This utility model relates to the field of insulation protection structure technology, specifically to an insulation protection structure for the exposed part of a cable joint used in cable reversing operations. Background Technology

[0002] Cable reconnection is a critical operation in power, communication, or network systems, switching existing cable lines to new ones. It's essential to ensure uninterrupted system operation and prevent accidents. When handling high-voltage electricity, exposed cable joints are prone to air breakdown, causing discharges and posing a danger to operators. Therefore, insulation protection structures can be used to protect the joints during the operation. However, existing protective structures involve bolting two half-pipes together to the outside of the cable and its joint. This assembly method, with the joint close to the equipment, limits the operating area, making the installation of the insulation protection structure inconvenient, and the bolted installation method is inefficient. Therefore, improvements to existing technology are needed. Summary of the Invention
