Description

technical field [0001] The invention relates to the field of electric cables, in particular to a shielding joint of a power cable suitable for an ultra-high voltage iron tower. Background technique [0002] Power cable accessories refer to the connection between various cables and intermediate connections and terminals in the cable line. According to their uses, they are generally divided into terminal connections and intermediate connections. Terminal connections are divided into indoor terminals and outdoor terminals. Generally, outdoor terminals refer to exposed antennas. Cable joint, indoor terminal refers to the connection between the cable and the electrical appliance; the intermediate connection is divided into two types: straight-through type and transition type. Two cables with the same type of insulation structure are connected to each other called straight-through type. Connections are called transitional. There are many types of cable accessories, each type has ...
