Most distribution cabinets are installed outdoors. In the process of using the distribution cabinet, people often reflect that when contacting the enclosure of the distribution cabinet, there will be a sense of electric shock. This is very dangerous for those distribution cabinets installed outdoors and have a high chance of contact with people. There are many reasons for leakage, which may be aging of the distribution cabinet shell, or the ground wire is not well connected or there is no grounding at all, or the aging of the wires may also be available. Therefore, the leakage situation should be checked first, and the reason for the disease is clear. The leakage can be large and small, and it is not too big to determine as soon as possible.

In order to prevent leakage of the enclosure of the distribution cabinet, the reliable method is to install some special leakage proof equipment in the distribution cabinet. Although the cost of this equipment is very high, it is very reliable, compared with the major loss caused by the accident caused by leakage. These inputs are valuable, or composite insulation materials can be used. Composite insulation materials have high functional insulation resistance and breakdown voltage, which can effectively avoid leakage accidents, maintain excellent dielectric motor energy at high frequency, do not reflect or block microwave transmission, and can be used for a long time without rust, and avoid electric shock of box.
