The busbar insulation coating is made of silicone - fluorinated rubber at room temperature. After chemical polymerization with fluorine-containing materials, adding flame retardant, arc resistance, reinforcement, active agent and other materials for physical mixing. It not only has good insulation performance, flame retardant and thermal conductivity, but also in the curing process, fluorine-containing monomer structural units migrates to the surface of the insulation layer, so that the surface of the insulation layer formed rich fluorine layer, so that the insulation layer has ultra-high ultraviolet resistance, high weather resistance, high durability, hydrophobic oil resistance and good aging performance.

The busbar insulation coating is made by polymer alloy technology. Its basic structural unit is composed of silicon oxygen link, and the side chain is connected with other organic groups through silicon atom. Therefore, its structure contains both organic group and inorganic structure. This special composition and molecular structure make it combine the characteristics of organic matter and the function of inorganic substance.

It is suitable for busbar, cable, wall bushing, high-power motor, dry-type reactor, dry-type transformer, switch cabinet and other equipment and components that need external insulation treatment, heat conduction, flame retardant and moisture-proof protection in high and low-voltage transmission and distribution system. It is especially suitable for electrical equipment working in dirty and humid environment. Moreover, it has the advantages of room temperature curing, in-situ molding, convenient use and direct spraying.

The busbar insulation coating manufactured by Ruisen can be used to protect bare wire, busbar, cable, high-power generator, dry reactor, dry-type equipment and components that need insulation, heat conduction, flame retardant, moisture-proof and so on. It is very suitable for electrical equipment operating in polluted and humid environment.

Although it is not a new maintenance technique, busbar insulation coatings are coated with electric porcelain insulators to improve their pollution resistance. There may be many people who do not know the working principle. Here is to introduce the working principle of busbar insulation coating:

Power station or line is built in the area where the pollution continues to increase over time. For example, there are industrial areas and expressways under construction nearby. Such construction will significantly change the degree of pollution that has a negative impact on the line or power station. We must take measures, otherwise the risk of flashover will be increased.

A thin layer of busbar insulation coating is applied on the surface of electric porcelain and glass insulator, which makes the original hydrophilic surface hydrophobic and greatly improves its pollution resistance. In addition, because the low molecular chains in silicone rubber continue to migrate to the surface, even if the surface is covered by a pollution layer, the ceramic insulator still remains hydrophobic.

More and more power companies choose busbar insulation coating. Another reason behind it is that the busbar insulation coating has both the electrical properties of silicone rubber and the mechanical properties of ceramics.

As the phenomenon of welding spatter is very common, the use of anti-spatter coating for welding is also very extensive. For general structural parts, the type of welding anti spatter coating has little effect, as long as it can effectively prevent welding spatter from adhering to the working surface in the welding process. However, for some key products and workpieces, such as high pressure vessels, if the anti-spatter coating contains too many harmful elements, it may cause spot corrosion, intergranular corrosion, etc. It will cause leakage in the subsequent operation of the equipment and lead to malignant accidents.

The selection of anti weld spatter coating also needs to be combined with the whole production process and process method. The process flow and process method mainly depend on the part after welding. At present, the technological process of structural parts is mainly divided into two categories: one is post-processing painting, the other is post-coating processing. If it is painting after processing, it must be cleaned before painting in order to remove rust and spray paint because cutting fluid will be used in the process of mechanical processing.

The type of anti weld spatter coating used in welding of the structure parts of the processed coatings has little effect. Even if oil-based anti-spatter coating is used, it can be completely removed by the cleaning process before painting, and the quality of the spray paint will not be affected. If the coating is processed or not processed, the use of oil-based anti weld spatter coating will bring some problems. Direct shot blasting treatment of structural parts can remove surface rust. But it is difficult to remove oil-based anti weld spatter coating coated on the weld seam of the workpiece. It will adsorb on the surface of the pellet, which causes pollution on the surface of some workpieces with oil stain, seriously affecting the adhesion of the paint film. In order to prevent the influence of oil-based anti-splash coating on subsequent painting, it is necessary to increase the cleaning process and carry out the necessary cleaning of the workpiece. Increasing the cleaning will bring a series of problems, such as production area shortage, cost increase, sewage discharge and so on. Therefore, for the workpieces processed or unprocessed after painting, oil-free anti weld spatter coating should be selected during welding, and water-borne or powder anti weld spatter coating should be used.

Hollow insulator is a special insulating control, which can play an important role in overhead transmission lines.

Historical roots

In the early years, insulators were mostly used in poles, and gradually developed into high-voltage wire towers with a lot of disc-shaped insulators hanging at one end. It was designed to increase the creeping distance, usually made of glass or ceramics, called insulators.

Production method

The hollow core insulators are composed of insulating mandrel inner barrel, end flange and silicone rubber umbrella sleeve. The silicone rubber umbrella sleeve is connected by more than two silicone rubber umbrella sleeve segments. The adjacent two silicone rubber umbrella sleeve segments are connected by step lapping structure. The end of the umbrella sleeve section finished in the previous processing is a step-type front lap ring with outer diameter less than the outer diameter of the umbrella sleeve section. The front lap ring of the umbrella sleeve section is coated with adhesive. The front segment of the umbrella sleeve completed in the latter processing is the back lap ring with the inner diameter matching the lap ring. The front lap ring and the back lap ring are bonded by adhesive.

Design and Implementation

According to the technical requirements of 1 000 kV UHV transmission project in China, the product design and process implementation scheme of hollow core insulators for SF6 combined electrical appliances are determined. The feasibility of the design scheme, the reliability of technical quality and the guarantee measures are expounded. Finally, it is pointed out that under the correct design scheme and reliable process guarantee, the composite hollow sleeve produced should be able to meet the needs of UHV transmission projects in China.

The Introduction of Station Post Insulator

The station post insulator is a special insulation control that can play an important role in overhead transmission lines. In the early years, the station post insulators were mostly used for utility poles. Then it slowly developed into a high-voltage high-voltage wire connection tower with one end hanging a lot of suspended insulators. It was used to increase the creepage distance, usually made of silica gel or ceramic, called insulator.Insulators play two fundamental roles in overhead transmission lines: one is supporting the conductors and the other is preventing current from returning to the ground. Insulators should not fail due to flashover breakdown due to changes in environmental and electrical load conditions, which can compromise the use and operational life of the entire line.

 

The Features of station post insulators high voltage

The insulator has high mechanical strength, small dispersion and safe and reliable operation.

The insulator has good mechanical properties at low temperature.

Excellent stain resistance.

High level of earthquake resistance.
