Community renovations, industrial expansion, and computing power booms often first strain power distribution capacity.
Residential Communities
Installation of elevators, high-load operation of air conditioners, and concentrated connection of EV charging stations in garages.
Public Facilities
Shopping malls, subways, and hospitals repeatedly see new peaks in electricity consumption.
Industrial Parks
Continuous deployment of smart manufacturing equipment, cold storage warehouses, and environmental protection equipment.
In these scenarios, capacity expansion becomes essential.
Either add a new transformer to share the load with existing equipment,
Or replace old units with new, higher-capacity models.
However, capacity expansion involves far more than just "installing larger equipment." A successful expansion requires comprehensive planning:
Accurate Load Calculation: Precisely assess new demand to avoid overload or excessive redundancy.
Parameter Alignment: Ensure voltage, frequency, and impedance match to prevent circulating current risks.
Ancillary Equipment Upgrade: Simultaneously optimize cables, busbars, and switchgear for a more stable system.
Peak Demand Margin: Incorporate short-time overload capability to handle instantaneous power surges.
Effective Temperature Management: Ensure proper ventilation and heat dissipation to prevent local overheating.
Protection Setting Optimization: Recalibrate overcurrent, short-circuit, and temperature protection settings for safety.
Holistic Planning: Develop an integrated solution considering space constraints, budget, or potential need for uninterrupted power supply.
Capacity expansion is a comprehensive upgrade involving capacity, safety, energy efficiency, and reliability. Consequently, SCB series epoxy resin dry-type transformers are frequently selected as the standard solution for 10kV capacity expansion projects, offering a cost-effective upgrade for existing distribution rooms.
Key Advantages:
Flame-retardant, fire-resistant, pollution-free; can be installed directly at load centers.
SCB13/14 series exceed GB/IEC standards; SCB18 series achieves Grade 1 energy efficiency.
Maintenance-free, easy installation, seismic-resistant, moisture-proof, and corrosion-resistant.
Supports online monitoring and remote early warning for higher efficiency and peace of mind.
CEEG Project Case Studies:
A Residential Area:
Original Setup: 2 x 500kVA transformers (Total capacity: 1000kVA).
Challenge: Concentrated connection of EV charging stations, combined with high summer AC usage, caused load growth exceeding capacity, leading to frequent power outages.
Solution: Added 1 x 800kVA epoxy resin dry-type transformer, increasing total capacity by nearly 50%.
Outcome: More reliable power supply during peak periods (summer AC, winter heating, nighttime charging).
A University New Campus:
Challenge: Rising electricity demand from laboratories, dormitories, libraries, etc., coupled with ongoing construction, led to insufficient capacity in the original system, causing voltage fluctuations during peak hours.
Solution: Expanded the original 1000kVA system capacity to 1600kVA and integrated intelligent monitoring.
Outcome: Stabilized power supply for teaching, research, and daily life, with early warning capabilities for potential abnormalities.
