Frequently Asked Questions
What are the primary applications for these stay insulators?
Stay insulators are primarily used in guy wires (stay wires) for overhead transmission lines or poles to provide insulation and structural safety, ensuring that current does not reach the ground through the stay wires.
What is the cantilever strength of the ANSI 54-4 model?
The ANSI 54-4 model features a robust cantilever strength of 91 kn, making it suitable for high-tension applications.
How does the creepage distance vary across different ANSI classes?
Creepage distance varies based on the size and design, ranging from 41mm for the 54-1 class up to 126mm for the Gy4 class, allowing for selection based on environmental pollution levels.
What are the electrical flashover voltage ratings?
The ratings depend on the model. For instance, the 54-4 model has a low frequency dry flashover voltage of 40kv and a wet flashover voltage of 23kv.
Are these insulators compliant with international standards?
Yes, these insulators are designed and tested according to ANSI (American National Standards Institute) standards, specifically classes like 54-1, 54-2, 54-3, and 54-4.
What is the weight range for these porcelain insulators?
The net weight starts from approximately 0.5 kg for smaller units like the 54-1 and goes up to 5.0 kg for larger units like the Gy4 class.
