Wall-mounted Intelligent Grounding Box

When the cable core conducts current, the metal shielding layer will generate an induced voltage. The induced voltage is directly proportional to the current flowing through the conductor and the length of the cable. When the cable line is asymmetrical, there is a short circuit, or it is subjected to operational overvoltage or lightning overvoltage, a relatively high induced potential will be generated. In severe cases, it can even break through the insulation of the protective layer. To ensure the normal operation of the power system and the safety of personnel, the metal sheath needs to be grounded using a grounding box. 

The wall-mounted grounding box occupies a small space, is easy to install, has excellent sealing performance, possesses good mechanical strength and outstanding anti-corrosion properties, and the box is sturdy, stable and reliable. The intelligent grounding box is compatible with the secondary monitoring system, which can conduct real-time monitoring and upload of various parameters such as the grounding current of the metal sheath, induced voltage, and operating current, replacing the traditional manual inspection. It is suitable for various operation and maintenance environments with high difficulty or harsh conditions, such as on terminal towers and in underground tunnels.
