Production Processes

  • Winding
    This is the process where conductive material, usually metal foil, is wound tightly to form the core of the capacitor. This winding is crucial for creating the capacitor's ability to store and release electrical energy.
  • Hot Pressing (Flat Core)
    Hot Pressing (Flat Core)
    Here, the wound core undergoes hot pressing to flatten it. This step is important for shaping the capacitor and can also influence its electrical characteristics.
  • Gold Spraying
    Gold Spraying
    Sputtering gold onto the capacitor components is likely a method of applying a very thin layer of gold. This layer can be important for improving conductivity and protecting against corrosion.
  • Heat Treatment
    Heat Treatment

    The components are subjected to heat treatment. This process can relieve stresses in the materials, improving durability, and ensuring the stability of the capacitor's electrical properties.

  • Core Testing (Energizing)
    Core Testing (Energizing)

    Testing the core, especially after energizing, is crucial. This step ensures the core to meet the necessary electrical specifications and is free from defects.

  • Welding
    Welding is used to securely connect various components of the capacitor. This step must be performed with precision to ensure structural integrity and reliable electrical connections.
  • Potting
    Potting involves encasing the capacitor in a protective material. This material protects the internal components from environmental factors and mechanical stress.
  • Final Product Testing
    Final Product Testing
    After assembly, the finished capacitor is rigorously tested. These tests confirm that the product meets all required specifications and performance standards.
  • Inspection
    A thorough inspection is conducted to ensure the quality of the finished product. This step is critical for maintaining high-quality standards.
  • Storage

    Finally, the capacitors that pass all tests and inspections will be stored, which are ready for distribution or further processing.

Industrial Type Capacitors Industry knowledge

How do industrial capacitor manufacturers select and optimize materials for industrial capacitors?

Material selection:
Dielectric materials: Choose materials with high dielectric strength, high dielectric constant and good stability. This helps ensure the industrial capacitor has low leakage current and high reliability. Common dielectric materials include polypropylene, polyester film, ceramics, etc.
Electrode materials: The selection of electrode materials should be based on their conductive properties, mechanical strength and stability. Metal films (such as aluminum, copper) are commonly used electrode materials, and they have excellent electrical conductivity and mechanical strength.
Electrolyte: For electrolytic capacitors, the choice of electrolyte is crucial. An electrolyte with high capacitance density, low leakage current and good stability should be selected.
Shell material: The shell material should have good insulation properties, high temperature resistance, corrosion resistance and other characteristics. Commonly used shell materials include epoxy resin, fiberglass, etc.
Material cost optimization:
Use cheaper materials: On the premise of meeting the performance requirements of the capacitor, choosing more reasonably priced materials can reduce production costs.
Optimize the use of materials: Reduce the use of materials through lightweight design and reduction of material waste, thereby reducing costs.
Manufacturing process optimization: Optimize the production process, improve material utilization, and reduce material loss.
Material performance optimization:
Research and develop new materials: Improve the performance of capacitors by developing new materials, such as increasing capacitance density and reducing leakage current.
Proper assembly: For capacitors with complex structures such as supercapacitors, proper assembly can ensure the synergy of electrode materials and electrolytes, thereby improving performance.
Strict quality control: Strict quality control is carried out on raw materials to ensure the consistency and reliability of materials.
Environmental factors to consider:
Environmental protection requirements: Choose materials that meet environmental protection requirements to reduce the impact on the environment.
Usage environment: Choose appropriate materials according to the usage environment of the capacitor to ensure that the capacitor can still work normally in harsh environments such as high temperature, high humidity, and high pressure.
Select the appropriate material by comprehensively considering factors such as the capacitor's usage environment, service life, rated voltage, operating temperature, and mechanical properties.
On the premise of meeting performance requirements, the material cost and production cost should be reduced as much as possible.

How does an industrial capacitor factory ensure that industrial capacitors have the ability to quickly respond to changes in the power grid and achieve dynamic reactive power compensation?

Select appropriate capacitor types and specifications: Select capacitors with appropriate capacity, voltage level and response speed based on the actual needs and characteristics of the power grid. This ensures that the capacitor can react quickly when the grid changes, providing the required compensation current.
Application of advanced reactive power compensation technology: Dynamic reactive power compensation technology is the key to enabling capacitors to quickly respond to changes in the power grid. Factories can use advanced reactive power compensation control strategies, such as current control and voltage control, to calculate the required compensation amount by real-time monitoring of the current and voltage of the power grid, and quickly adjust the output current of the capacitor to achieve dynamic reactive power compensation.
Optimizing the design and manufacturing process of capacitors: By optimizing the design and manufacturing process of capacitors, their performance and stability can be improved. For example, high-quality materials and advanced production processes are used to ensure that parameters such as capacitor capacity, voltage level, and response speed meet requirements. In addition, capacitors can also be subjected to strict testing and quality control to ensure that they can work stably and reliably in actual use.
Integrated intelligent control system: Factories can integrate intelligent control systems to remotely monitor and control capacitors. By collecting grid data in real time, the intelligent control system can analyze the operating status of the grid and adjust the output current of the capacitor as needed. This can not only improve the response speed of the capacitor, but also reduce the labor intensity of the operator and improve production efficiency.
