قائمة التحقق من الاختيار
Specify the Vacuum Circuit Breaker for the Network
- Define the electrical duty. State rated voltage, continuous current, frequency, short-circuit breaking current, making current and insulation levels.
- Choose the construction. Confirm outdoor or indoor installation, common-box or pole-mounted arrangement, vacuum interrupter and insulation medium.
- Match the operating mechanism. Specify manual, motor or stored-energy operation, trip/close coil voltage, auxiliary contacts and control interface.
- Check the site environment. Provide altitude, ambient temperature, humidity, pollution, wind, seismic and enclosure requirements.
- قائمة الوثائق والكمية. Include drawings, wiring diagram, routine-test evidence, packing, destination market and delivery requirements in the RFQ.
الحدود الخاصة بالتكوين والإمداد
Review the Column Configuration
The supplier listing identifies a vacuum-circuit-breaker model family. State the exact model code and switching arrangement so the quotation does not mix ratings or accessories from another series.
Mechanism and controls
Specify stored-energy mechanism, motor and coil voltages, auxiliary contacts, interlocks and local/remote control.
Structure and environment
Confirm pole arrangement, insulation housing, enclosure, altitude, temperature, pollution and installation interface.
الحدود التجارية
Quantity, packing, delivery schedule, private label and project documents remain subject to technical review and quotation.
