Problems solved by technology

The disadvantage of this kind of distribution cabinet is that the insulation performance is not good, and it will cause serious safety hazards when the line is short-circuited, and the product is relatively heavy and inconvenient to install.
In recent years, plastic power distribution cabinet shells have been researched, which have good insulation performance and small weight, but have poor mechanical properties, corrosion resistance and thermal conductivity, and cannot withstand large impact forces. Discharge of heat generated during power-on can easily cause high temperature in the power distribution cabinet and bring potential safety hazards, such as the plastic power distribution cabinet shell disclosed in Chinese invention patent CN201010236519
