Abstract
A low-tension cable connector for an underground transformer comprises an insulating plinth. One end of the insulating plinth is provided with a sealed top cap. The inner side of the lower end of the sealed top cap is connected with a cable jacket by threads. The outer side of a lug boss at the lower end of the cable jacket is provided with a screw cap. The inner side of the screw cap is connected with a base by threads. An insert is arranged in the middle of the base and the top end of the insert is connected with a joint, the other end of which is connected with the low-tension cable. The lower end of the insert is connected with a lead wire. The connection with the low-tension coil of a transformer core can be realized. The utility model separates the phase of the low-tension cable from the earth effectively, which has the advantages of good sealability, large current-carrying capacity, good insulativity, practicality and reliability.
Description
Technical field
The utility model relates to electric power facility, particularly is used to connect the low-voltage cable connector of underground transformer, especially a kind of underground transformer low-voltage cable connector.
