Indoor and outdoor high and low voltage power distribution projects
The indoor and outdoor high and low voltage power distribution engineering is the core foundation of the building's power supply system, responsible for converting external high-voltage power (such as 22.8kV) into low-voltage electricity (380V/220V) required by the building through transformer equipment, and then steadily distributing it to each power usage area.
The engineering content covers high-voltage equipment (such as substations and switchgear), low-voltage distribution panels, cable trays, conduit installation, grounding protection, and power control systems, coordinated with indoor and outdoor space design for overall wiring and configuration.
Applicable to various types of buildings such as factories, hospitals, commercial buildings, residential communities, and data centers. Through good design and construction, it ensures stable, safe, energy-saving power supply and ease of maintenance, making it an indispensable part of the building's electromechanical systems.
Power System Planning and Design
Design high-voltage (161KV/69KV, etc.), medium-voltage (22.8kV/11.4kV, etc.), and low-voltage (380V/220V) distribution systems based on building usage and power load requirements, covering primary/secondary circuits, circuit planning, and load balancing calculations.
High-Voltage Substation Equipment Installation
Responsible for the selection and installation of high-voltage switches (VCB/GIS), transformers (oil-immersed or dry-type), grounding systems, and protective devices to ensure safe and stable power step-down.
Electrical Panel and Low-Voltage System Construction
Install low-voltage switchboards, motor control centers, lighting panels, and distribution boards, and lay out cable conduits, cable trays, protective devices, etc., to support electrical needs of different areas within the building.
Integration of Automated Control and Monitoring Systems
Implement smart meters, PM (Power Meter), load monitoring, remote management systems, etc., to effectively monitor power usage and energy management.
Testing, Validation, and Maintenance
Complete electrical tests such as grounding impedance, insulation, winding resistance, and withstand voltage tests in coordination with power delivery operations and validation. Subsequently, provide periodic maintenance, thermal imaging inspection, and troubleshooting services.
