About HV Bushing For Transformers
We are providing a wide variety of 33 KV HV Bushing For Transformers. They are used to protect and link a transformers high voltage winding to the outside world. The purpose of these transformers are to give the transformer a way to connect to a high voltage transmission or distribution system 33 KV HV Bushing For Transformers are provided to run at that voltage. Typically, flanges are used to mount them to the transformer tank. To maintain the effective operation of these transformers, routine maintenance is required.

FAQs of HV Bushing For Transformers:
Q: How should I install the HV bushing to ensure optimal performance and safety?
A: For proper installation, mount the bushing vertically, ensure the gasket is correctly sealed, and follow all torque specifications outlined in the datasheet. This prevents moisture ingress and ensures long-term reliability.
Q: What benefits does the porcelain glazed surface provide for this HV bushing?
A: The porcelain glaze enhances dielectric strength, increases resistance to weather and pollution, and offers superior anti-tracking properties, ensuring the bushing operates safely and reliably in various environmental conditions.
Q: When and where is this bushing most suitably applied?
A: This HV bushing is ideal for both industrial and commercial transformer installations where high voltage up to 33 kV and currents between 4001250 A are required. Its weather resistance and robust construction make it suitable for outdoor and demanding settings.
Q: What materials are used in the construction of the bushing and why?
A: The body is crafted from high-density porcelain for excellent insulation, while the inner conductor uses copper or brass for superior electrical conductivity. This combination ensures high performance, safety, and long operational life.
Q: How does the bushing mitigate the risks of tracking and arcing?
A: A creepage distance of 900 mm and an arcing distance of 490 mm reduce the risk of surface tracking and electrical arcing. Additionally, the glazed coating further inhibits the formation of conductive paths across the surface.
Q: What are the advantages of the optional oil level indicator?
A: The optional oil level indicator provides real-time monitoring of oil conditions within the transformer, supporting preventive maintenance and reducing the risk of operational failures caused by low or contaminated oil.
