We all know well that many electrical equipment failures are related to dampness and dampness. How should the bottom sealing of the cabinet be constructed? It has always been a concern for power operation and maintenance personnel. In humid environments, the threat faced by indoor power facilities is becoming increasingly apparent, which has a significant impact on the safe operation of electrical equipment. In electrical engineering, when the relative humidity is greater than 80% RH, it is called high humidity; Excessive humidity is the main factor in electrical equipment accidents.

It has always been a concern for power operation and maintenance personnel. In humid environments, the threat faced by indoor power facilities is becoming increasingly apparent, which has a significant impact on the safe operation of electrical equipment. In electrical engineering, when the relative humidity is greater than 80% RH, it is called high humidity; Excessive humidity is the main factor in electrical equipment accidents.

  To prevent moisture and dehumidification, it is necessary to block the infiltration of moisture and moist air. Before putting the bottom of the cabinet into use or during renovation, polymer moisture can be used to block the bottom and cut off the circulation path of cold and hot air. The first is to avoid moisture, naturally, condensation cannot be avoided without moisture. Secondly, it can prevent the entry of small animals from causing damage to electrical equipment.

  The bottom sealing of the cabinet is a new type of environmentally friendly moisture-proof sealing agent, specifically used for outdoor ring network cabinets, box transformers, high and low voltage switchgear, centralized control unit cabinets, and other electrical equipment. Polymer moisture-proof sealant has the characteristics of low viscosity, good flowability, easy penetration, no deformation, no deterioration, and no cracking. The bottom gap of the electrical equipment is completely sealed; Capable of withstanding natural temperature freeze-thaw cycles and various harsh environments, effectively preventing small animals from entering enclosed cabinets from underground. It is a good plan for the safe operation of electrical equipment in the power grid and for moisture-proof and leak sealing operations.

  The advantages of sealing the bottom of the cabinet are as follows:

  High safety: waterproof, moisture-proof, dustproof, fireproof, and flame retardant.

  Simple operation: simple construction, single person operation, no need for assistance (electricity, fire, water, etc.).

  Good flowability: Fully flow and automatically level on the sealing surface before curing.

  Withstand various harsh environments: corrosion-resistant, able to withstand various harsh environments.

  Strong adhesion: tightly integrated with cable sheaths and surrounding building structures, without corrosion reactions.

  Firm structure: A solid molecular closed cell matrix structure with good toughness and light weight after molding, which will not break or fall off.

  Durable effect: After solidification, it does not deform, deteriorate, or crack, and has a service life of 10 years.

  Convenient construction: It can be used on the suspended ceiling or directly on the bottom plate, making it an ideal choice for electrical equipment safety protection. The secondary opening is simple and convenient.

  The necessity of sealing the bottom of cabinets is becoming increasingly important in people's awareness. The faults caused by moisture condensation have indeed sounded an alarm for the power industry. The harm of humidity to electrical equipment cannot be ignored. We have many years of experience in the industry of sealing the bottom of cabinets. If you want to learn more about relevant content, you can contact us.
