Problems solved by technology

Due to the wide application of electricity in social production and human life and the rapid development of electronics and communication technology, the power distribution cabinet, as an integral part of the substation, is exposed to harsh outdoor weather all year round and is susceptible to aging and reduced service life due to ultraviolet radiation.
[0003] On the other hand, there are two ways to install electrical equipment: surface installation and concealed installation. The heat dissipation effect of surface-mounted electrical equipment is better than that of concealed electrical boxes. The air in concealed electrical equipment is not suitable for convection, and its heat dissipation effect is poor, resulting in The air temperature of the surrounding environment rises due to the temperature rise of the low-voltage circuit breaker in the power equipment

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an insulating coating for external use of power equipment and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of my country's national economy, the demand for electricity has shown a rapid growth trend. In order to meet the needs of industrial and agricultural products and people's daily life, substations with a voltage level of 110kV and above are gradually built in the central area of ​​the city. Due to the wide application of electricity in social production and human life and the rapid development of electronics and communication technology, the power distribution cabinet, as an integral part of the substation, is exposed to harsh outdoor weather all the year round, and is susceptible to aging and reduced service life caused by ultraviolet radiation. [0003] On the other hand, there are two ways to install ...
