Electric Cabinet Potting Silicone for Ring Network Cabinet

INTRODUCTION
It is common for the power industry to cause troubles due to the damp.
        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
        HY-230 high polymer dampproof plugging agent is well known as a perfect potting material, encapsulating material as well as sealing material, it's a perfect plugging agent for new energy vehicle charging pile, distribution network outdoor ring network cabinet, box type transformer, cable branch box, distribution network control cabinet and substation outdoor terminal box, mechanism operation box, electric knife switch box, high and low voltage switch cabinet, junction control unit cabinet, distribution room, etc.

WHY USE HIGH POLYMER PLUGGING AGENT FOR ELECTRIC CABINET
1. The phenomenon of damp - Plugging.
        Ring network cabinet is used to protect the transformer and limit the short circuit current, to prevent the transformer from the sudden short circuit fault current, and to quickly cut off the short circuit fault within 10ms, so as to prevent the transformer from damage caused by the pressure rise caused by internal arc, so that the transformer can be protected more reliably and reasonably, ring network cabinet plays an indispensable role in power system, so once the ring 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 sealing 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. If the condensate reaches a certain level, it will drip onto the components in the cabinet, causing creepage, short circuit, etc. and condensation and corrosion will be formed in the cabinet. If it is light, the switch will touch by mistake, and if it is heavy, the fire will break out and 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 potting the ring network cabinet.


2. The moisture-proof sealing materials used in the existing traditional cable trenches are mostly inorganic blocking materials or fire-proof bags, which are of poor stability. Once they are eroded by moisture or washed by rain, they will be affected by moisture and deformation, which will greatly reduce the effective performance of fire retardant, which is difficult to achieve the normal effect of fire-retardant and fire prevention and moisture-proof! And if there is a fire inside the cable trench, the consequences are unthinkable!

3. The fire-proof mud was used to block the bottom of the cabinet and cable mouth in the past. After more than one year of operation of the cable junction box, the fire mud at the bottom of the cabinet appeared oil flow, cracking, collapse, aging and falling off phenomenon, which had poor sealing effect and lost the function of moisture-proof sealing, which made the cabinet easy to have condensation and safety hazards brought by small animals, It is seriously threatening the operation safety of power equipment and cannot meet the requirements of moisture-proof sealing, so it is necessary to re block, and the disadvantages such as high maintenance cost of fire-proof mud and short durability time are gradually exposed. After long-term use, fire mud has many disadvantages, such as heavy pollution, easy to destroy, collapse, easy to dry and crack, easy to be polluted.
