Selection of the outer shell of the ring network cabinet
Generally speaking, when the ring main unit is placed indoors or in a distribution room, a separately constructed space can provide protection, so there is no need to consider the shell design separately. However, when there is no additional sheltering building and the ring main unit needs to be placed outdoors, the choice of shell must be taken into account.
The outdoor environment can have many uncertain factors affecting the operation of the ring main unit, such as rain, storms, lightning, and damage from plants and animals. In this case, the ring main unit needs to be adequately protected to isolate these environmental impacts and extend its service life. Common types of shells include GRC, aluminum-zinc coated panels, and stainless steel (304, 201).
GRC shell is common in residential areas. The non-metallic box transformer shell made of GRC material has great plasticity, and its size variation is not restricted. Due to its short construction time, it will not overly affect residents' travel during the construction or renovation of the community, and the noise generated during construction is also limited to a short period. It occupies a small area and has a relatively beautiful appearance, which will not overly damage the landscape in communities with high aesthetic requirements.
Aluminum-zinc coated panels, also known as galvanized aluminum panels, are a type of metal shell composed of an aluminum-zinc alloy structure. They have various high-strength characteristics: corrosion resistance, high-temperature resistance, and ease of painting. These characteristics make this type of shell have a longer service life and more suitable for some outdoor environments that are more complex.
Stainless steel shells (304, 201) are also one of the more common shell materials. Stainless steel has become a common material for tableware or home appliances in daily life, and using it for the ring main unit shell also has good corrosion resistance, making it the preferred shell material in many outdoor environments.
Additionally, depending on project and environmental needs, for aesthetic purposes, decorative anti-corrosion wooden strips, anti-corrosion tiles, or painted shells can also be chosen. Through decoration, the ring main unit can blend into diverse environments without appearing out of place, combining functionality and appearance. Anti-corrosion wooden strips and anti-corrosion tiles are common in outdoor balconies and gardens, being both beautiful and requiring little maintenance, while painted shells can be customized according to needs, reflecting landscapes, flowers, birds, and cultural sentiments, making it a more artistic form of decoration.
