ILJIN’s transformers are in service around the world and meet international standards such as IEC,ANSI
The SF6 Gas Insulated Switchgear (GIS) contains major substation equipment, such as the gas circuit breaker, disconnecting switch, earthing switch, voltage transformer, current transformer, and lightning arrester, within a grounded metallic enclosure filled with SF6 gas to provide the best possible insulation and arc-quenching capabilities.
ILJIN’s GIS is the most highly-developed switchgear on the market today. Our products provide features such as compact designs, safety, reliability, simplified operation, long maintenance intervals and compatibility with surrounding systems. Our recently developed 3-phase encapsulated GIS is an example of the economical and compact substation design our customers have come to know and expect from ILJIN.
[Feature & Advantage]
1) Reliability
·A circuit breaker which surpasses the KERI and KEMA standards outlined in the latest IEC standards (IEC 62271-203 & IEC 62271-100).
·A phase common enclosure for fewer components and no errors.
·A high-quality circuit breaker featuring a hydraulic operating mechanism (170kV GIS) or a motor operated spring mechanism (25.8kV, 36kV, 72.5kV GIS, 145kV GIS, 245kV GIS).
2) Compact Design
·A small and lightweight phase common enclosure design (72.5kV GIS, 145kV GIS, 170kV GIS).
·A CT housed in the CB and a line disconnecting switch, line earthing switch, and work earthing switch contained in a single enclosure to reduce size and weight.
·A CB motor operated spring mechanism adopted to make our GIS lighter and more compact than comparable models (25.8kV, 36kV, 72.5kV GIS, 145kV GIS, 245kV GIS).
3) Safety
·Earthed enclosure to provide improved protection against current leakage.
·Interlocking system to optimize system operation.
4) Modular Design
·Standardized modules to improve production quality and allow for easy assembly.
5) Gas Tightness
·Standardized sealing ring (O-ring) system to reduce the number of pipes and valves in each system and improve gas tightness.
6) Adoption of the Puffer & Hybrid Type Gas Circuit Breaker
·Puffer & hybrid type gas circuit breaker for simplified construction, fewer components, no gas heating of components, and enhanced reliability.
The encapsulated type MV GIS(25.8/36kV) is installed at a substation to safely and promptly break fault current as well as load current. This product is intended to improve the supply reliability by isolating defective sections and restricting propagation of accidents. It is also designed to enhance stability with high-speed reclosing.
