Abstract

The invention discloses a shielding joint for power cables, comprising a joint body, a first shielding part, a second shielding part, a pressure handle, an outer shielding shell, and a handle ring. The first shielding part is arranged in the upper part inside the joint body, and the second shielding part is arranged in the lower part inside the joint body. The pressure handle is arranged inside the first shielding part. The outer shielding shell is arranged outside the joint body. The handle ring is arranged on the outer shielding shell. Through the technical scheme, the shielding joint for power cables of the invention has excellent insulating, sealing and shielding functions, and is applicable to power systems of ultrahigh-voltage towers.

Description

technical field [0001] The invention relates to the field of cables, in particular to a shielding joint for power cables. Background technique [0002] Power cable accessories refer to the connection of various cables and intermediate connections and terminals in the cable line. Together with the cables, they form a transmission network; cable accessories are mainly based on the characteristics of the cable structure, which not only satisfies and restores the performance of the cable, but also ensures the length of the cable. extension and terminal connections. According to its use, it is generally divided into terminal connection and intermediate connection. Terminal connection is divided into indoor terminal and outdoor terminal. Generally, outdoor terminal refers to open-air cable joint, and indoor terminal refers to the connection between cable and electrical appliances; intermediate connection is divided into straight-through There are two types of type and transition ...
