Integrates high-voltage switchgear, transformer, and low-voltage distribution equipment within a semi-buried enclosure, enhancing protection against water, freezing, and corrosion. It reduces surface land occupation while improving visual integration with the surrounding environment and ensuring convenient operation and maintenance.
Suitable for space-constrained downtown zones, focusing on freeing up surface land and optimizing underground installation.
Landscape-Sensitive Areas
Applicable to parks, squares, and public spaces, emphasizing visual harmony with surroundings and low-noise operation.
Urban Renovation Projects
Ideal for redevelopment and restricted construction areas, focusing on fast retrofitting, easy installation, and accessible maintenance channels.
Product Description
1
Structural and landscape integration: One-third or two-thirds of the enclosure is buried underground, reducing above-ground height and achieving better environmental integration.
2
Excellent underground structural performance: Steel frame combined with BFE composite enclosure provides waterproof, frost-proof, anti-seepage, and corrosion-resistant protection.
3
Flexible electrical configuration: High-voltage side supports ring network or radial (terminal) solutions, while low-voltage side can be configured as fixed or panel-type design.
4
Easy and efficient installation: Simple foundation requirements; installation can be completed with a leveling layer, significantly reducing civil work and construction time.
