Compact medium-voltage solutions that combine busbar and switching functions in a sealed gas tank. Ring-main, transformer-protection and metering functions can be configured according to the single-line diagram.
Gas-insulated switchgear provides a compact architecture for distribution substations where installation space is limited.
Depending on the selected product family, ring-main units can combine load-break switching, transformer protection, circuit-breaker and metering functions in block or modular arrangements.
Rated voltage, current, short-time withstand, internal arc classification and dimensions are finalized according to the selected product family and approved technical data.
| Voltage Class | 12 / 24 / 36 kV |
| Insulation Medium | SF6 gas — according to selected product family |
| Construction | Block / modular |
| Functions | LBS / protection / metering |
| Rated Current | According to product family |
| Short-Time Withstand | According to product family |
| Reference | IEC 62271-200 |
Technical drawings and project documents are prepared according to the selected configuration and project requirements. You can request the following documents during the quotation process.
System voltage, feeder arrangement, transformer rating, short-circuit level, protection philosophy, motorization and remote-control requirements are required for correct selection.
