Frequently Asked Questions (FAQ)
What are the recommended service conditions for this equipment?
The equipment is designed for altitudes not exceeding 2000 meters. The ambient temperature range should be between a minimum of -30°C and a maximum of +40°C. Additionally, the installation site must be free from explosion hazards, severe vibrations, and elements that cause significant corrosion to metals or insulating materials.
What materials are used for the iron and stainless steel parts?
All iron accessories are hot-dip galvanized to a thickness of over 80um to ensure superior corrosion resistance. Stainless steel components are made of high-quality 304 stainless steel. Precision-cast brass or aluminum bronze options are also available.
What configurations are available for the upper terminal block?
The upper terminal block is available in two types: tin-plated copper castings and silver-plated stamped parts, allowing you to choose the best option for your conductivity and application requirements.
What is the rated voltage range for these models?
Depending on the specific type, the rated voltage ranges from 12kV up to 27(36)kV, with impulse voltages (BIL) ranging between 110kV and 200kV to match various high-voltage specifications.
Does the fuse tube offer environmental protection?
Yes, the fuse tube is specifically designed to be UV-resistant and moisture-proof, ensuring a long-lasting service life under outdoor operating conditions.
