Definition and classification: Wire box cover is a protective measure used for line joints in power lines. It mainly covers the line connection parts to prevent moisture, dust, corrosion, etc., so as to ensure the normal operation of wires and cables. According to different uses, it can be divided into two types: wire box covers with plug-in and pull-out functions and wire box covers without plug-in and pull-out functions.

Function: 1. Moisture-proof: The line joints are exposed to the environment for a long time and are susceptible to erosion by rain and moisture. The use of wire box covers can prevent moisture from infiltrating and causing short circuits, and at the same time effectively avoid corrosion problems caused by air oxidation of cables.

2. Dustproof: The line joints are located at high altitudes or in open areas and are susceptible to contamination by a large amount of dust or sand. The wire box cover can be used to prevent dust, sand, dust, etc. from entering the circuit joints and causing dust pollution, affecting the normal operation of the power lines.

3. Anti-corrosion: The circuit joint part may cause circuit failure due to corrosion. The use of wire box cover can prevent corrosion caused by oxidation.

Installation and maintenance: The wire box cover needs to be maintained and inspected regularly during use to ensure the normal operation of the circuit joints. At the same time, it is also crucial to install the correct cable box cover. Pay attention to the installation location, installation method, fastening nuts, and positive and negative polarity symbols.
