1. VITZROTECH GIS(Gas Insulated Switchgear) INTRODUCE
● VITZROTECH provides a Closed Gas Insulation Switchgear (C-GIS), a multi and
advanced switchgear, to local and overseas electric power systems in order to operate
them smoothly, to measure and monitor their status and to protect them in case of
failures. GIS is installed in incoming transfer facilities of substations, buildings, factories
and public facilities and it interrupts the load current and the fault current safely and
promptly. It separates the fault section and limits the failure extensions so as to improve
the supply reliability and to enhance the power stability by applying functions including a
● It has enough space for its compact design and it is convenient to use.
- Due to the excellent dielectric strength of SF6 Gas, the width of unit circuit which determines the
installation size is reduced to 600mm resulting in downscaling of the size required for installation.
● It is easy to manufacture and install so the production and installation periods are
- It is assembled with standard components so it is convenient to couple and operate. It is easy to carry
around on site and its installation is so simple that is reduces the installation cost.
● It is easy to operate for it is in a convenient and safe structure.
- The charging part that forms the electric line is installed inside the ground metal which ensures the
safety of operators and inspectors.
● It is easy to perform the maintenance work due to various protection and
- It is a new-concept product with SF6 Gas that aims for a flawless and maintenance-free product. It is
highly reliable and it does not require the maintenance work for a long period of time.
- It is a product that harmonizes with the modernized surrounding due to the user-centered external
structure, low noise and minimized inductive interference.
