Flame Retardant Plugging Agent for State Grid Bidding

INTRODUCTION
        The role of ring network cabinet is to protect the transformer and limit the short circuit current, to prevent the transformer from suffering from sudden short circuit fault current, and to quickly cut off the short circuit fault within 10ms to prevent transformer damage caused by the pressure rise caused by internal arc, and to make the transformer more reliable and reasonable protection. The ring network cabinet plays an indispensable role in the power system, So once the ring network cabinet is damp, it has great security risks to the operation of the power grid. The principle of sealing the ring network cabinet is to block the inlet and outlet, holes and door joints of each ring network cabinet, to prevent the entry of wet air, and prevent small animals from entering the enclosure from the underground, thus reducing the safety hazards; It can realize the airtight and moisture-proof inside the cabinet, and provide strong protective barrier for the production and operation equipment.

        Once the ring network cabinet is invaded by humid air, it is easy to condense in the ring cabinet in a moment. Condensate reaches a certain leve, the degree will drop on the components in the cabinet, causing creepage, short circuit, etc., and condensation and corrosion will be formed in the cabinet. If the switch is light, the switch will be touched by mistake, and serious fire may also cause safety accidents. At present, there are not a few accidents caused by the tide of the ring network cabinet in China. It is very important to prevent moisture from blocking the ring network cabinet.


        It is common for the power industry to fail due to the tide. Humidity has a certain degree of damage to electrical equipment, which will affect the safe operation of power equipment, so it is imperative to do well in the work of moisture-proof and dehumidification.



APPLICATION
        High polymer dampproof plugging agent, it is a new environment-friendly moisture-proof sealant specially used for distribution network outdoor ring main unit, box type transformer, cable branch box, distribution network control cabinet and substation outdoor terminal box. The polymer moisture-proof plugging agent adopts high polymer mixing technology and high active chemical substance formula, with low viscosity, good fluidity, self leveling, easy penetration, no deformation, no deterioration No cracking. Fully seal the gap at the bottom of electrical equipment; It can withstand natural temperature freeze-thaw cycle and various harsh environments, and effectively prevent small animals from entering the closed cabinet from underground. It is an excellent scheme for safe operation of power grid electrical equipment and moisture-proof plugging operation.



ADVANTAGES
High safety: waterproof, moisture-proof, dust-proof, prevent small animal invasion, fire retardant

Simple operation: simple construction, single person operation, without auxiliary (electricity, fire and water, etc.), the surface can be dried quickly in 30 minutes

Good fluidity: fully flow on the sealing surface before curing and automatically level, without manual grinding

Resistant to all kinds of harsh environment: anti-corrosion, can withstand all kinds of harsh environment

Tight adhesion: closely combined with cable sheath and surrounding building structure, no corrosion reaction

Solid structure: solid molecular closed cell matrix structure, toughness, light weight after molding, will not break or fall

Lasting effect: no deformation, deterioration and cracking after curing, and the service life is more than or equal to 10 years

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

Polymer dampproof plugging self leveling material: the plugging agent flows into the target area fully and automatically on the sealing surface before curing, so it does not need to be smoothed, and the construction is simple. It can quickly and conveniently flow through the complex through pipes or cables and other cabinets, fill the irregular surface, and finally form a solid shape.

Component properties: two in one polymer materials with high active chemicals.

Curing property: forming a solid closed cell matrix after solidification.

Chemical resistance: it can prevent the chemical corrosion of gasoline, petroleum, dilute acid and alkali, base and most unsaturated hydrocarbons.

Field application: fully mix the solution, slowly pour the mixed solution on the target surface, and the field application can be completed after the surface of the mixed solution is dry.

Re repair: new cable or secondary construction can be carried out with woodworking knife. After completion, pour some moisture-proof plugging agent into the opening to seal the area. After the newly added cables or pipelines are installed, some additional moisture-proof plugging agents shall be used   You can seal the area again.


With all kinds of metal materials, cable maintenance material can be closely bonded, and does not produce any adverse chemical reactions, ensure the safe operation of electrical equipment in power grid.
