Description

[0002] The controller box is a metal shell specially used to hold and fix electrical controllers, mainly used to centrally manage, protect and manage various lines and connectors of electrical equipment. It is usually made of cold-rolled steel plate or other similar materials, with good durability and corrosion resistance.

[0003] According to the relevant provisions of GB5017, the cables entering and exiting the top or bottom of the control cabinet and the cable ports must be sealed with fireproof plugging.

[0004] At present, the existing controller box inlet plugging is mostly carried out by sealing putty, fireproof cotton strips and nano-ceramics. However, the sealing putty mainly relies on the physical adsorption of the material to achieve the sealing effect. The disadvantage is that it is easy to be affected by moisture and loses its sealing performance over time, which cannot meet the long-term use requirements; the fireproof cotton strip has good high temperature resistance and corrosion resistance, but the sealing effect of the fireproof cotton strip is poor and it is easy to fall off; nano-ceramics has good corrosion resistance and oxidation resistance. However, its cost is very high and the construction is difficult. Utility Model Content
