Frequently Asked Questions (FAQs)

What are high voltage corona rings used for in Chinese factories?

High voltage corona rings are crucial in Chinese factories, particularly in the context of power transmission and distribution. They are used to reduce the effect of corona discharge in high voltage transmission lines, whether AC or DC, thereby improving the efficiency of power transmission. These rings help in minimizing energy losses and ensuring stable power supply, making them essential components in power supplies, high voltage generators, and HV test systems.

How are high voltage corona rings installed in measurement systems?

Installing high voltage corona rings involves several steps to ensure they function correctly. First, you need to check if the properties of the ring meet the system’s requirements. The installation should be done in a clean and dry environment, away from dust and conductive substances. Common installation methods include using a flange or a clamping device, both typically made of polyurethane, to secure the ring inside pipes or on other components.

What materials are commonly used to make high voltage corona rings in China?

High voltage corona rings in China are often made from aluminum alloy, which offers good insulation performance and anti-corrosion properties. These materials can withstand a wide temperature range, making them suitable for various environmental conditions. For instance, aluminum corona rings can operate between -55°C to +180°C, ensuring long-term reliability and efficiency.

How do I choose a reliable high voltage corona ring manufacturer in China?

Choosing a reliable manufacturer involves several steps. Start by researching potential manufacturers online and visiting their official websites to understand their company scale, product catalog, and application fields. Request samples or visit the factory to assess product quality. Also, inquire about quotations and compare prices to ensure you get the best value. This thorough approach will help you find a manufacturer that meets your specific needs.
