Cubic Gas-Insulated Switchgear
The CGIS switchgear is a new joint product of Mehrabad Company and DECOM of Germany. All main components of the switchgear, including the disconnector, breaker, and transformers, are placed in a metal enclosure filled with SF6 gas, which, in addition to creating high safety, eliminates the need for repairs and maintenance and prevents the ingress of moisture, dust, and oxidation into the main parts of the switchgear.
Other advantages of using this type of switchgear::
- Compact design and less space required for installation and operation
- Maximum operational safety due to inaccessibility to live parts
- No contact of high-voltage parts with external factors
- Separate compartment for earthing switch and circuit breaker
- Safe against all ARC FAULTs
- Use of safe busbar technology and simple installation
