New energy cable manufacturers share experience and knowledge in cable industry

When the new energy cable manufacturer shares with you the connection between the two ends of the cable and other electrical equipment, it needs a connection device that can meet certain insulation and sealing requirements. This device is called cable terminal. The cable terminal head can be divided into indoor head and outdoor head according to the different use occasions. The device that connects several cables to form a longer cable line is called the middle head. Connect the above power

Precautions for locomotive cable operation

Precautions for locomotive cable line operation (1) Do not overload or overheat for a long time. Therefore, the monitoring of cable load current, external temperature and joint temperature should not be ignored; (2) The cable line feeder protection shall not be put into reclosing. Most of the cable line faults are permanent faults. If the reclosing action is taken, the accident will inevitably expand and threaten the power grid
