Industry Knowledge About Epoxy Powder-coated Insulated Busbars

 

Epoxy powder-coated insulated busbars are insulated busbars formed by coating copper or aluminum conductors with epoxy powder as the insulating material through a specific process. Epoxy powder is a thermosetting dry powder with excellent insulation performance, chemical corrosion resistance, and mechanical properties, which can provide reliable insulation protection for the busbar.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Characteristics of epoxy powder coating

Excellent insulation performance: The Insulation Coating Busbar has high dielectric strength, which can effectively prevent current leakage and short circuit phenomena, ensuring the safe operation of electrical equipment. Its insulation resistance is high and can maintain stable insulation performance in a wide temperature range.

Good heat resistance: Generally, it can be used for a long time at a temperature of 120℃-150℃. Some specially formulated Electroplating and Powder Coating Busbars can even maintain stable performance at higher temperatures, meeting the requirements of heat resistance of busbars in different industrial environments.

Strong mechanical properties: The cured Epoxy Powder Coat Busbar forms a hard protective layer with good wear resistance, scratch resistance, and impact resistance. It can resist mechanical stress and impact from external objects, protect the busbar conductor from damage, and extend the service life of the busbar.

Chemical corrosion resistance: It has strong corrosion resistance to a variety of chemical substances such as acids, alkalis, salts, etc., and can effectively protect the busbar in a chemical corrosion environment to prevent the conductor from being corroded and causing performance degradation.

 

Production process

Pretreatment: The busbar conductor is pretreated by degreasing and rust removal to remove impurities such as oil, rus,t, and oxide scale on the surface, improve the adhesion of the Powder Coated Busbar to the conductor, and ensure the firmness and quality stability of the coating.

Coating method: There are mainly two methods: the fluidized bed method and the electrostatic spraying method. The fluidized bed method requires preheating the busbar first and then passing it through a fluidized bed containing suspended Busbar Coating with Epoxy Coating Powder. The powder melts under heat and evenly adheres to the surface of the conductor to form a thicker coating, which is suitable for coatings of complex shapes and large busbars; the electrostatic spraying method uses electrostatic action to adsorb the charged epoxy powder to the grounded busbar surface and then forms a coating through baking and curing. The coating thickness can be precisely controlled, which is suitable for busbar production with more precise coating thickness requirements.

Curing: Put the busbar coated with Busbar Insulating Coating Powder into a baking oven and cure it at a certain temperature to make the powder undergo a cross-linking reaction to form a hard coating. Control of curing temperature and time is crucial to the performance of the coating.

Insulation Performance Standard: It is necessary to meet the corresponding insulation resistance, and withstand voltage strength and other index requirements. For example, under normal environmental conditions, the insulation resistance of the busbar should not be lower than a certain value to ensure the insulation safety of electrical equipment.

Heat Resistance Grade Standard: According to different application scenarios and use environments, Nickel-Plated Insulated Bus Bars should meet the corresponding heat resistance grade standards, such as 155℃, 180℃, and other heat resistance grades, to ensure long-term stable operation in high-temperature environments.

Mechanical performance standards: Including coating adhesion, hardness, impact strength, and other indicators, which should meet the requirements of relevant standards to ensure that the coating will not fall off, crack, or be damaged when subjected to mechanical stress, and ensure the mechanical strength and reliability of the busbar.
