Frequently Asked Questions
Oil-immersed cooling provides superior heat dissipation and insulation, allowing the regulator to handle higher loads and operate in extreme temperatures without overheating.
Yes, thanks to its fully enclosed structure and high protection level, it is specifically designed to resist dust, insects, and harsh weather conditions.
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.
It is typically used in electrical machinery manufacturing, power distribution stations, and industrial plants requiring stable voltage for heavy equipment.
The internal oil-cooling system manages heat effectively, though standard clearance around the enclosure is recommended for optimal natural convection.
While designed for long-term stability, we recommend a professional inspection every 12-24 months to ensure oil purity and level optimization.
