Description

Dry-type insulated cable terminal Technical Field The utility model relates to the technical field of insulated cable terminals, in particular to a dry insulated cable terminal. Background The dry insulated cable termination is a structural member for connecting and fixing the ends of insulated cables and is widely applied to power systems. The cable adopts solid insulating materials (such as silicone rubber and epoxy resin) and sealing design, ensures the drying of the inside of the cable and maintains the insulating property. The prefabricated sealing structure needs to be accurately aligned and installed, and special tools (such as hydraulic devices) can be applied to the prefabricated sealing structure during on-site assembly, so that the prefabricated sealing structure is heavy to operate, and the sealing layer is required to be damaged or special tools are required to be used during disassembly, so that the maintenance efficiency and convenience are affected. Such inconvenience not only limits its application in frequent installation and removal scenarios, but may also lead to unstable cable connections or increased risk of electrical leakage, potentially affecting the reliability and safety of the power system. In view of this, the present application proposes a dry insulated cable terminal. Disclosure of utility model Accordingly, an object of the present utility model is to provide a dry insulated cable termination, which simplifies the installation and removal processes, improves the sealing performance and the operation efficiency, and ensures the long-term stable operation of the cable termination, so as to solve the technical problems described in the background art. The utility model is realized by the following technical scheme: The utility model provides a dry-type insulated cable terminal, includes both ends cable body around, the front end cable body outer wall fixedly connected with installation head, the rear end cable body outer wall fixedly connected with butt joint, installation head outer wall threaded connection has the swivel becket, the equal fixedly connected with fixed pipe of four sides of installation head front end outer wall, fixed pipe front end inner wall sliding connection has the press head, press head inner wall is connected with the gripper jaw through dismantling the group, butt joint inner wall fixedly connected with bears the ring, bear ring front end fixedly connected with a plurality of connector.
