The Liuzhou China Resources Land development encompasses formats such as shopping malls, office buildings, and apartments. Its power distribution system needs to meet the following requirements:
Load Dispersion: Different areas of the commercial complex require localized power distribution.
Space Constraints: Underground distribution rooms must maximize the release of commercial area.
Safety Redundancy: Equipment in high pedestrian traffic areas requires 100% insulation protection.
Environmental Adaptation: Liuzhou's annual rainfall exceeds 1500mm, requiring equipment to be moisture and condensation-proof.
Inefficient Use of Underground Space: Traditional switchgear occupies commercially valuable areas.
Large Fault Impact Range: Radial power supply schemes mean a single point of failure can cause outages for multiple tenants.
Electric Shock Risk in Public Areas: Power distribution equipment in areas like pedestrian streets poses risks if exposed live parts are accessible.
Frequent Faults in Humid Environments: Insulation components in traditional cabinets are prone to moisture absorption and tracking in humidity >90%.
Space Saving: Minimum width of 420mm, reducing footprint compared to traditional cabinets.
Environmental Immunity: Stainless steel gas chamber filled with 0.02MPa dry air, completely isolating it from moisture erosion.
Maintenance-Free Design: Integrated three-position switch structure eliminates mechanical interlock failure points.
Load Tapping Hub: Supports 8 feeder branches, distributing power locally to dispersed loads like plaza lighting and charging piles.
Rapid Fault Isolation: Enables isolation of single circuits during area maintenance, ensuring normal power supply for other tenants.
Public Safety Assurance:
Fully insulated, touchable cable terminations ensure zero surface potential, eliminating risk upon accidental contact.
IP67 stainless steel enclosure provides rain and dust protection, suitable for Liuzhou's rainy environment.
Optimized Space Utilization: Compact gas-insulated switchgear and strategic placement of outdoor switching cabinets reduce the footprint of underground distribution rooms.
Enhanced Power Supply Reliability: Modular structure allows for live-line maintenance on single circuits, minimizing tenant outage impacts.
Strengthened Safety Compliance: Fully insulated design meets the mandatory safety code GB50053-2013 for commercial area power distribution.
Whole-Life Cycle Economical Benefits: Maintenance-free characteristics of gas-insulated switchgear reduce upkeep costs; modular expansion capability of switching cabinets adapts to future operational adjustments.
