Abstract
Description
Technical Field
[0001] This utility model relates to the field of power construction technology, and in particular to a cable preparation mold. Background Technology
[0002] In power systems, cable connection and termination are critical links. When preparing cable joints on site, it is usually necessary to use molds to inject insulating materials (such as polyurethane, silicone rubber, epoxy resin, etc.) to form an insulating protective layer of a specific shape. Existing on-site fabrication molds have the following drawbacks: Traditional split molds often use multiple bolts for fastening, and are mostly fixed in size. The assembly and disassembly process is time-consuming and labor-intensive, affecting construction efficiency. Furthermore, if the gap between the mold and the cable is not sealed properly, it will lead to leakage of potting compound, resulting in material waste and joint quality defects. In addition, the cured insulation material is prone to sticking to the inner wall of the mold, and forced demolding may damage the surface of the formed joint or the cable insulation layer. Therefore, there is an urgent need for a cable connector preparation mold that is versatile, easy to operate, easy to demold, and has good sealing performance. Utility Model Content
