Junengda 500 kva Pad Mounted Transformer FAQ>>>
Q1: What is the primary application of Junengda’s 500 kVA pad-mounted transformer?
Junengda’s product is designed for underground power distribution systems, ideal for commercial complexes, residential subdivisions, and industrial facilities. Its compact, corrosion-resistant enclosure ensures reliable power delivery in diverse environments.
Q2: How does Junengda ensure the safety of its 500 kVA pad-mounted transformers?
Safety is engineered into every Junengda product. It features robust overvoltage protection against both internal surges (e.g., switching operations) and atmospheric surges (e.g., lightning strikes), preventing insulation damage and equipment failure1. Grounding resistance adheres to ≤10Ω standards to eliminate electrical hazards.
Q3: What protection standards does the transformer’s enclosure meet?
The product enclosure is rated IP68 (Ingress Protection), offering complete dust resistance and waterproofing for submerged conditions. Heavy-gauge steel construction and corrosion-proof coatings extend its lifespan in harsh climates.
Q4: Can Junengda’s 500 kVA transformer handle voltage fluctuations?
Yes. Our pad-mounted transformers include on-load tap changers (OLTC) to adjust voltage levels ±5%–10%, ensuring stable output despite grid fluctuations. This prevents voltage-related disruptions for critical loads.
Q5: What grounding requirements apply to installation?
Per international safety standards, the grounding resistance must not exceed 10Ω. Junengda provides integrated grounding terminals and detailed guidelines to achieve compliant, low-resistance grounding systems.
Q6: Are these transformers suitable for high-lightning areas?
Absolutely. Junengda pad-mounted transformers incorporate lightning arresters and shielded windings to dissipate surge currents. Maintain a safe distance (≥10 meters) during storms to avoid step-voltage risks.
Q7: What maintenance does a Junengda 500 kVA pad-mounted transformer require?
Routine maintenance is minimal. We recommend annual inspections of bushings, coolant levels (for liquid-filled units), and enclosure integrity. Junengda transformers are designed for >30-year service with proper upkeep.
Q8: Does Junengda offer customization for specific project needs?
Yes. Customize voltage ratings (e.g., 11kV/400V, 33kV/480V), cooling methods (liquid or dry-type), and enclosure dimensions. Contact our engineering team for bespoke solutions.
Q9: What certifications do Junengda transformers hold?
All 500 kVA pad-mounted transformers comply with IEC 60076, IEEE C57.12.20, and ANSI standards. Optional certifications (UL, CE) are available for regional markets.
