Withdrawable CE Certificates HV GIS High Voltage Switchgear for Substations
Product Description
It is a high voltage gas insulated switchgear suitable for electrical substations.
• The withdrawable circuit breaker design allows breakers to be withdrawn for maintenance without de-energizing the whole switchgear.
• CE certification ensures the product meets European Union health, safety and environmental standards.
Advantages:
• Flexible maintenance - Circuit breakers can be maintained independently without affecting other parts. This reduces downtime.
• Higher reliability - The disconnecting function ensures accurate positioning and reliable insulation during maintenance.
• Improved safety - Live circuits are fully isolated when circuit breakers are withdrawn, protecting maintenance personnel.
• Compact design - The withdrawable mechanism is more space-efficient compared to fixed circuit breakers.
Application:
• Primary and secondary distribution in electrical substations of power generation, transmission and distribution systems.
• High voltage switching in industrial facilities with their own substations like steel plants, oil refineries, etc.
Key features:
• Rigid and reliable gas insulation - SF6 gas provides excellent insulation and arc extinguishing properties.
• Low losses and efficient power transmission -due to high insulation resistivity of SF6 gas and compact structure.
• Maintenance-free - Sealed-for-life design requires no additional maintenance during long service life.
• Compact design - Achieves high current and voltage ratings within small footprint due to GIS technology.
• High operational safety - Interlocks, earth switches and other protections ensure personnel safety during operation and maintenance.
In summary, the key value propositions are flexible maintenance, high reliability, improved safety and a compact design enabled by the withdrawable circuit breaker and GIS technology.
