Frequently Asked Questions
Q: What are the main benefits of oil-immersed cooling in voltage regulators?
Oil-immersed cooling provides superior heat dissipation and insulation, allowing the regulator to handle higher loads and operate in extreme temperatures without overheating.
Q: Can the 400 kVA regulator be installed outdoors?
Yes, thanks to its fully enclosed structure and high protection level, it is specifically designed to resist dust, insects, and harsh weather conditions.
Q: How does this unit handle extreme temperature fluctuations?
The unit is engineered for full-load operation from -25°C to +50°C, using materials that prevent structural loss during rapid day-night temperature changes.
Q: What is the primary application for a 400 kVA capacity regulator?
It is typically used in electrical machinery manufacturing, power distribution stations, and industrial plants requiring stable voltage for heavy equipment.
Q: Does the enclosed structure require special ventilation?
The internal oil-cooling system manages heat effectively, though standard clearance around the enclosure is recommended for optimal natural convection.
Q: How often should the oil in the regulator be inspected?
While designed for long-term stability, we recommend a professional inspection every 12-24 months to ensure oil purity and level optimization.
