1Community Power Supply Solution | Safe and Reliable Power Supply System for Communities and Buildings

The community power supply system is crucial for providing safe, stable, and efficient electricity to modern communities, including apartment buildings, residential complexes, and residential buildings, directly affecting the quality of life of residents and the normal operation of community facilities. With the acceleration of urbanization and the continuous growth of residents’ power demand, residential developers and power suppliers are facing increasingly prominent key challenges. Our community power supply solution is designed to solve these pain points, providing a fully integrated compact power distribution system that integrates transformers, switchgear, and protection equipment. It can reduce installation space by 40%+, shorten construction cycle by 35%+, lower maintenance costs by 25%+, and fully meet the safety and stability requirements of community power supply, bringing reliable power guarantee to urban communities.

Challenges Faced by Community Power Supply

Urban community power supply systems face unique challenges due to limited space, high safety requirements, growing power load, and difficult maintenance, which traditional power distribution systems are difficult to fully meet.

2.1 Limited Space

Urban residential projects are often constrained by land resources, with obvious space limitations: the installation space for electrical equipment is extremely limited, especially in high-density residential areas, where even a small area of land occupation will increase project costs; urban land prices are high, and building large-scale substations will significantly increase the investment cost of residential projects; underground infrastructure is restricted by urban pipeline layout, making it difficult to arrange complex power distribution equipment, which increases the difficulty of construction.

2.2 Safety Requirements

Residential users have strict requirements for power supply safety, which is directly related to personal and property safety: they need stable voltage supply to avoid equipment damage caused by voltage fluctuations; high electrical safety performance to prevent electric shock, fire and other safety accidents; and a complete fault protection system to quickly isolate faults when abnormalities occur, minimizing safety risks. Once a safety accident occurs, it will not only cause economic losses but also affect the reputation of developers and power suppliers.

2.3 Growing Power Demand

With the improvement of residents’ quality of life and the popularization of smart home equipment, modern buildings have an increasing demand for power, which puts higher requirements on the load-bearing capacity of the power supply system. The equipment that needs power supply includes elevators (the core equipment for high-rise buildings, which cannot be interrupted), central air conditioning systems (large power consumption, long running time), smart home devices (increasing types and quantities), and electric vehicle charging facilities (rapidly popularizing in communities). The peak power load of medium-sized communities has increased by 30% in the past 5 years, and traditional systems are difficult to adapt.

2.4 High Maintenance Difficulty

The community power supply system is closely related to residents’ daily life, so it must minimize downtime, maintenance frequency, and operational complexity. Traditional power distribution systems have complex structures, and maintenance requires professional personnel to operate for a long time, resulting in long power outages (average 3-4 hours per maintenance), high maintenance frequency (once every 2-3 months), and high operational complexity, which not only affects residents’ life but also increases the operational cost of power suppliers.

Solution Core Principle / Architecture

Our community power supply solution is a fully integrated compact system, specifically designed for residential complexes, apartment buildings, and commercial-residential buildings, adhering to the core principle of “compact design, safe and reliable, efficient and energy-saving, easy to maintain”. The solution fully complies with IEC, UL, and IEEE international standards, ensuring the safety, compatibility, and stability of the system in global urban community scenarios, and meeting the relevant safety and environmental protection requirements of various countries.

The core technical logic of the solution is to integrate all functional modules (medium-voltage power distribution, transformation, low-voltage distribution, protection and control) into a compact integrated system, abandoning the traditional scattered layout mode, which not only saves installation space but also simplifies the construction process and improves the stability of the system. The system architecture is clear and efficient: starting from the main power grid, the box-type substation or ring main unit (RMU) is used for power switching and fault isolation, then the transformer (oil-immersed or dry-type) converts medium voltage to low voltage, and finally the low-voltage power distribution cabinet transmits stable power to each residential building and apartment, ensuring the safe and stable power supply to end users.

The core product combination of the solution is carefully selected for community scenarios: medium-voltage power distribution system (KYN28 high-voltage switchgear, ring main unit RMU), compact substation unit (YB European-style box-type substation, ZBW American-style box-type substation), power distribution transformer (oil-immersed transformer, SCB dry-type transformer), low-voltage power distribution system (GGD low-voltage switchgear, GCK drawer-type switchgear, GCK reactive power compensation cabinet), and protection equipment (ZW32 outdoor vacuum circuit breaker, ring main unit protection equipment). All products have passed strict quality certification, with compact structure, stable performance, and low noise, fully meeting the needs of community power supply.
