As Hyundai GIS use puffer type gas circuit breakers, gas-heating components have been eliminated. The number of components are drastically reduced. This simple construction gives simple maintenance, allowing contacts of circuit breakers to be exchanged without any disassembly.
Carefree from Land Shortage
As the selection of switchgear type is largely dependent on available space, a compact-type switchgear is essential. In comparison with the conventional outdoor switchgear, GIS substation requires only 5-10% of installation space. Now Hyundai GIS enables you to install the substation in a densely populated area or even under residential buildings.
As Hyundai GIS comprises standardized modules, further expansion can be easily considered.
Carefree from Hazards
As almost all the live parts of the switchgear are kept in the earthed enclosure, operators can secure enough safety. Furthermore, as the seal-off system of Hyundai GIS has a minimal number of pipes and valves, reliability for tightness can be secured.
