Product Overview
The MD-12/0.4 system consists of two main parts: the highly waterproof underground transformer vault and the above-ground distribution cabinet. This split design minimizes visual impact and noise pollution in densely populated areas such as commercial streets, residential complexes, and parks.
Product Features
- Maximum Space Optimization: Replaces bulky traditional substations with a discrete above-ground footprint, freeing up valuable land for pedestrians or landscaping.
- Extreme Waterproofing (IP68): The underground transformer and its high/low voltage connections are fully sealed. It can operate safely even when completely submerged in water during heavy rains or floods.
- Aesthetic Integration: The above-ground cabinet can be customized to function as an illuminated advertising light box, an information kiosk, or a landscape feature, blending seamlessly into the cityscape.
- Low Noise and Radiation: Burying the transformer effectively shields electromagnetic radiation and acoustic noise, improving the quality of life for nearby residents.
- Corrosion and Rust Protection: The underground pit and transformer tank are treated with special anti-corrosion materials to withstand soil moisture and chemical environments.
Technical & Artistic Details
The engineering behind the MD series focuses heavily on thermal management and environmental resilience.
- Innovative Cooling: The underground pit utilizes natural and forced ventilation systems, often with wind-driven exhaust fans built into the above-ground unit to ensure optimal transformer cooling.
- Maintenance Access: Designed with secure, easily operable manhole covers and lifting mechanisms for safe inspection and maintenance of the underground units.
