Reliable Insulation and Safety
Featuring porcelain insulation and test voltages of up to 38 kV, these transformer bushings ensure safe and consistent operation. The creepage distance, tailored as per rating, minimizes leakage and corona discharge. Optional arcing horns further protect against transient overvoltages, enhancing service life and safety.
Flexible Installation Options
Choose between flange or stud mounting types for seamless integration into indoor or outdoor transformer setups. Copper or brass terminals ensure efficient connectivity, while color options in brown and light grey allow for aesthetic compatibility with various installations.
FAQs of Transformer Bushings of 12, 17.5 KV:
Q: How do Transformer Bushings with porcelain insulation improve performance?
A: Porcelain insulation provides excellent mechanical strength and electrical resistance, protecting transformers from environmental factors such as moisture, dust, and pollution. This ensures reliable performance and minimizes maintenance needs.Q: What is the recommended usage for these bushings?
A: These bushings are specifically designed for transformers with voltage ratings of 1217.5 kV and are suitable for both indoor and outdoor applications. Their construction allows them to handle currents between 250 and 1250 Amps, meeting diverse operational requirements.Q: When should an arcing horn be provided on the bushing?
A: Arcing horns are optional features recommended for installations where theres a higher risk of transient overvoltages or in outdoor environments. They offer an added layer of protection during electrical surges, enhancing the lifespan of the bushing.Q: Where are these bushings typically installed?
A: They are typically installed in power distribution and industrial transformers, both indoors and outdoors, across utilities, substations, and manufacturing units throughout India.Q: What is the manufacturing process for porcelain insulated bushings?
A: The manufacturing process involves shaping high-grade ceramic materials, firing them at elevated temperatures, and then assembling with metallic fittings (copper or brass) for terminals, ensuring a strong, dependable product for high-voltage applications.Q: How does the creepage distance affect bushing reliability?
A: A greater creepage distance, ranging from 245 to 430 mm, reduces the risk of surface leakage currents and flashovers, especially under high pollution or humidity conditions, thereby increasing operational safety.Q: What are the benefits of choosing a flange or stud type mounting?
A: Flange or stud mounting types provide flexibility for installation, making it easier to match the bushing to the transformers design requirements, simplifying the replacement process, and ensuring long-term stability.Tell us about your requirement
