Miniaturized Double-Layer Substations Solve Upgrade Challenges in Old Urban Power Distribution Equipment, Empowering High-Quality Urban Development

With urban development, power upgrades in old urban areas face numerous challenges: difficult site selection, long construction cycles, unstable power distribution quality, and resident concerns about equipment safety and noise. The Miniaturized Double-layer Prefabricated Substation launched by Haihong Electric, with its outstanding advantages of small footprint, high safety, and reliability, is becoming a "powerful assistant" in the power equipment renovation of old urban areas, providing efficient and convenient solutions for the transformation and upgrading of urban power distribution equipment.

"Going Upward for Space" to Solve Site Selection Challenges

Core areas of old cities are highly valuable, where land is scarce. Traditional substations, with their large footprint, struggle to find a place. The miniaturized double-layer substation series adopts a pioneering patented double-layer design, "going upward for space" for the equipment, significantly reducing the footprint. It can be flexibly embedded in limited spaces like old residential communities and narrow streets. The Miniaturized Double-layer double-transformer Substation series can meet the high-capacity power distribution needs of dense urban areas with minimal land use, eliminating the need for large-scale demolition and land clearance, thereby greatly reducing renovation costs and difficulties.

Coexisting Safely with Residences for Harmonious Integration

Addressing safety and noise concerns of power distribution equipment in old urban areas, the miniaturized double-layer substation series provides comprehensive solutions. The Fully Insulated Open Ventilated 3D Wound Core Dry-type Transformer it employs possesses excellent fire and explosion resistance, eliminating the risk of oil leakage and fire associated with traditional pole-mounted oil-immersed transformers from the root cause. Furthermore, the product operates with low noise, avoiding noise disturbance issues, allowing the equipment to be better accepted by community residents and enabling harmonious coexistence.

Ensuring Stable Power Supply and Improving Distribution Quality

Improving power supply stability is key to power distribution renovation in old urban areas. The miniaturized double-layer substation series utilizes a self-developed zero-carbon eddy current pressurized scalable cooling system, featuring low operational temperature rise and strong overload capacity. It can calmly handle the impact of extreme load fluctuations in densely populated urban areas. Additionally, the double-layer double-transformer substation adopts multi-power supply system technology, further enhancing power supply reliability and providing a solid guarantee for the stable operation of regional energy systems.

"Grounding" Outdoor Pole-Mounted Transformers, Setting a Renovation Benchmark

In multiple locations such as Shenzhen and Guangzhou, original outdoor pole-mounted oil-immersed transformers have been successfully "grounded" and replaced with miniaturized double-layer substations. These projects not only give a "new look" to urban villages and streets in various areas but also provide replicable and promotable successful experiences for upgrading outdoor power distribution facilities in similar regions.

The miniaturized double-layer substation series product solutions not only significantly improve the utilization efficiency of land resources but also provide strong technical support for building a new type of green power grid and smart grid. In the future, Haihong Electric will continue to empower urban renewal with technological innovation, revitalizing old communities, enhancing urban quality, and contributing professional expertise to the improvement of people's livelihoods.
