1. Industrial Production:
Factories and mines consume large amounts of electricity and have numerous devices. Distribution cabinets convert high-voltage electricity to usable low-voltage electricity and provide protection for large motors, production lines, cranes, etc., preventing short circuits or overload damage.
Factory Workshops: Provide power and control protection for various motors, machine tools, robots, conveyors, and other equipment on production lines.
High-Energy-Consuming Industries such as Steel, Chemicals, and Cement: Distribute power to high-power equipment and possess special functions such as harmonic and interference suppression.
Data Centers: Provide highly reliable power distribution for servers, storage devices, and cooling systems, often working in conjunction with UPS (Uninterruptible Power Supply).
Water Treatment and Supply Systems: Control pumps, valves, dosing devices, etc., to achieve automated operation.
2. Civil Buildings:
Distribution cabinets prioritize safety, ease of use, and integration with the surrounding environment.
Residential communities: Indoor electrical distribution boxes for each household, public lighting distribution cabinets in corridors, elevator distribution cabinets, and fire pump distribution cabinets.
Commercial buildings: Floor distribution cabinets, lighting control cabinets, air conditioning unit distribution cabinets, escalator/elevator distribution cabinets, as well as emergency lighting distribution cabinets and fire-fighting power distribution cabinets, must meet fire resistance requirements.
Public facilities: Various power and lighting distribution cabinets in hospitals (with particular emphasis on power supply continuity), schools, stadiums, airports, and subway stations.
3. Public and Transportation Facilities:
In airports, subways, high-speed rail stations, and other similar locations, power distribution cabinets supply power to signaling systems, lighting, automatic ticket vending machines, security equipment, etc. Their reliability directly impacts operational safety. Power distribution cabinets in highways and tunnels provide power for monitoring, ventilation, and emergency lighting.
Road Traffic: Traffic signal control cabinets, street lighting distribution cabinets, highway toll station and tunnel ventilation and lighting distribution cabinets.
Urban Pipelines: Control cabinets for water supply and drainage pumping stations, power distribution cabinets in municipal utility tunnels.
New Energy Facilities:
Photovoltaic Power Stations: Combiner boxes, DC distribution cabinets, AC distribution cabinets.
Electric Vehicle Charging Stations: Distribution cabinets providing overall power distribution for charging pile groups.
Energy Storage Systems: Control and protection distribution cabinets between battery packs and inverters.
4. Commercial Specialty Locations:
Catering and Kitchens: Dedicated distribution boxes supplying power to high-power equipment such as electric stoves, steamers, and refrigerators, requiring consideration of high-temperature, high-humidity, and oily environments.
Stage and studio: Stage power distribution cabinets providing numerous adjustable and controllable circuits for lighting, sound, large screens, etc.
Planting and animal husbandry: Environmental control (fans, wet curtains, supplemental lighting) power distribution cabinets for greenhouses; automatic feeding and sewage control cabinets for livestock farms.
Temporary or event occasions: Temporary power distribution boxes for construction sites, large events (concerts, exhibitions), and disaster relief sites; often outdoor waterproof types are used.
