Models: ZF9-252/T4000-50 and ZF9-252/Y4000-63
Specifically designed with operational components contained in a sealed metal container filled with insulating gas, this class of GIS reduces installation space requirements, is more resistant to weather conditions, and is easier to maintain.
Considering future expansion, the 252kV GIS is capable of growing with your system while adhering to wiring requirements and standards. For greater application flexibility, the 252kV GIS can be configured for either single-phase or three-phase common bus arrangements.
Main Features
- Innovative design offering a common bus for three phases and a separate enclosure for single-phase circuit breakers.
- Compact GIS with reduced dimensions: L x W x H: 6600mm x 1800mm x 3150mm
- Circuit breaker drive mechanism with a spring (50kA) or hydromechanical (63kA) device.
- For horizontal circuit breaker configurations, the electrical control compartment manages all three phases simultaneously.
- Integrated earthing switches.
- Disconnector and Earthing Switch (DES).
- Exclusive sealing technology (less than 0.5% leakage per year).
- Maintenance cycle of 20 years.
Advantages
- Smaller footprint: With a cell designed to fit on standard transportation vehicles, transportation and installation costs are reduced, eliminating the need for specialized transportation equipment.
- Ease of installation: The integration of the local control panel and GIS results in a compact design with completed factory secondary wiring diagrams, reducing on-site installation and commissioning time and costs.
- High reliability: For components of the Disconnector, Earthing Switch, and Fast Earthing Switch, the mechanisms for all three phases are directly connected, ensuring a compact structure with greater reliability.
- Ease of transportation: As the mechanical units form a compact common enclosure for three phases with a minimal number of moving parts, adjustments between phases are minimized. The compact design of the equipment also significantly reduces transportation costs and on-site installation time.
