Description

TECHNICAL FIELD

[0001] The utility model relates to high voltage cable joint installation tool technical field, concretely is a kind of high voltage cable joint sliding installation tool. BACKGROUND

[0002] The installation of high voltage cable joint is mostly in sliding mode, and in order to ensure that rubber insulation is not damaged or is easy to install during installation, special tools are needed to pull the rubber insulation onto the cable for installation operation. The existing installation tool is composed of two parts: a special pull cone plate and a nylon transition plate. During installation, the two are used together. The nylon transition plate needs to be placed in the special pull cone plate first and then fitted onto the rubber insulation for operation. This ensures the moderate cooperation between the three to prevent the special pull cone plate from deviating from the rubber insulation during the pull cone process, causing damage to the insulation. After the pressure connection is completed, the rubber insulation needs to be pulled from one side of the cable to the other side. Therefore, only the special pull cone plate needs to be placed on the rubber body.

[0003] The existing installation tool has the following disadvantages when in use: 1. When in use, the outer diameter of the rubber insulation increases as it is pulled into the cable, causing the nylon transition plate to be stuck to the rubber insulation, which is difficult to remove and can easily damage the rubber insulation. 2. The cross-section of the cable is different, and the outer diameter is also different, resulting in the need to process many different sizes of special pull cone plates and nylon transition plates, which is costly. To address the above issues, we propose a high voltage cable joint sliding installation tool. UTILITY MODEL CONTENTS
