The copper bus is CNC cut, punched, and bent to ensure accuracy.
Leybold Helium Mass Spectrometry Leak Detector, Germany -- ensures that the leakage rate of SF6 gas tank is below the national standard.
Computer-controlled equipressure pumping and inflating integrated equipment for vacuum chamber -- to ensure no deformation of gas box and 99.9% purity of SF6 gas.
Product parameters:
Conditions of use:
Altitude shall not exceed 2000m.
Ambient air temperature not higher than +40 °C, not lower than -5 °C (average temperature within 24 hours not higher than +35 °C).
The humidity of the surrounding air should not exceed 50%. Low temperature allows a large relative temperature (e.g., +20 °C is 90%). Consideration should be given to the effect of condensation caused by temperature changes.
Inclination with vertical plane is not more than 5°, and the whole group of cabinets is relatively flat, in line with (GBJ232-2) standard.
Requested in no violent vibration and impact, electrical components will not be corroded, no conductive dust place.
Ordering instructions:
The customer shall provide the following information:
Main loop scheme diagram, secondary loop system diagram, and auxiliary circuit control mode.
Equipment layout and distribution room layout.
Brand and model of main electrical components of the equipment.
Incoming and outgoing lines.
Other special requirements can be negotiated with WONE Electric.
What are the structural characteristics of the RMU SF6?
Fully Sealed and Fully Insulated:
SF6 gas has excellent insulating properties. The ring main unit (RMU) uses SF6 gas for common box insulation, with all switching components sealed within the main enclosure. This design effectively prevents external environmental factors such as condensation, contamination, and flooding from affecting the internal electrical components, ensuring safe and reliable operation. The protection level typically reaches IP67.
Compact and Space-Efficient:
The design is compact, requiring a small footprint, allowing it to be installed in limited spaces. It is suitable for various outdoor locations, such as city streets, residential areas, and industrial parks, effectively saving space resources.
Corrosion-Resistant Design:
The enclosure is typically designed with special anti-corrosion features and painted with a protective coating, providing good resistance to corrosion. This allows the equipment to withstand harsh environmental conditions such as acid rain and salt fog, extending its service life.
