Choosing high/low voltage switchgear is like picking clothes-it depends on the occasion and needs. Industrial, commercial, and residential scenarios each have their own considerations. Here's a quick breakdown:
1. Voltage Level First
High Voltage Switchgear: Designed for 6000V and above, suitable for heavy industries like factories and mines.
Low Voltage Switchgear: Handles 220V and below, the mainstay for commercial and residential buildings.
2. Choose by Scenario
Industrial Scenario
Needs: High load, frequent start/stop, anti-interference required.
Recommendations:
GCS Type Draw-out Low Voltage Switchgear: Modular design allows individual fault unit replacement, ideal for automated factories.
KYN28A-12 High Voltage Switchgear: Features "five-prevention" functions, the top choice for metallurgy, chemical, and other heavy industries.
Commercial Scenario
Needs: Continuous power supply, convenient management.
Recommendations:
GGD Type Fixed Low Voltage Switchgear: Moderate cost, high breaking capacity, suitable for malls and office buildings.
MNS Type Digital Low Voltage Switchgear: Equipped with touch-screen operation, enables real-time energy consumption monitoring, aligning with smart energy management.
Residential Scenario
Needs: Safety, simple operation.
Recommendations:
JP Integrated Distribution Box: Combines metering and protection, easy for property staff to operate.
Outdoor Floor-standing High Voltage Metering Box: Complete isolation of high and low voltage, eliminating electric shock risks.
3. Key Parameters to Consider
Rated Voltage: Low voltage switchgear typically AC380V, high voltage above 6000V.
Protection Level: Industrial requires IP40 or higher, commercial/residential IP30 is sufficient.
Breaking Capacity: Industrial scenarios need high breaking capacity to avoid production line shutdowns.
4. Price Reference
Low Voltage Switchgear: Yongye Da 10kV Low Voltage Switchgear 1325 yuan; Xinchuan Electric GCK Low Voltage Switchgear 4859 yuan.
High Voltage Switchgear: KYN28A-12 type approximately 15,000-30,000 yuan (specific price requires inquiry).
