Aktif Gas Insulated Switchgears are manufactured in order to reduce environmental effects of SF6 gas and offer a more sustainable solution by using dry air gas in the insulation environment. Gas insulated switchgears are manufactured and tested LSC-2 service continuity, PM partition, AFLR internal arc classification, according to IEC 62271-200 standard and up to 36 kV, 2000 A and 31,5 kA/3s.
Optimum reliability is ensured in your facilities thanks to sealed pressure system that does not require maintenance for at least 30 years. AGIS, which are manufactured with type tests taken from International Accredited Laboratories, consist of 4 compartments:
- Busbar Compartment: Compartment where electrolytic copper busbars according to rated current, post insulators and optional current and/or voltage transformers can be mounted.
- Switching Compartment: This compartment with 3-position disconnector and/or vacuum type circuit breaker is in a completely closed, stainless steel tank that is leakproof to industrial dry air gas (~ 80% Nitrogen + ~ 20% Oxygen).
- LV Compartment: Compartment where all measurement devices, protection relays, terminal connections, communication devices and other protection and control equipment that is used in the system are located.
- Cable Compartment: Optionally, current and/or voltage transformers can be located in this section where cable connections are made.
AGIS provides compact and strong solutions thanks to IP3X protection class for using indoor applications.
AGIS series Gas Insulated Switchgears provide maximum savings in application area with their minimized dimensions and compact designs. It provides a high level protection and security against wrong maneuvers by mechanical and electrical interlocks.
Aktif Gas Insulated – Dry Air Gas Insulated Switchgears are free from following costs needed for SF6 GIS.
- Specialized SF6 gas equipment
- SF6 reporting obligations
- SF6 certification of personnel
- SF6 inventory keeping

What are the differences and advantages between SF6 and Dry Air Gas ?
Insulation Features:
Dry air gas (~ 80% Nitrogen + ~ 20% Oxygen) is used instead of SF6 gas in the switching compartment of Dry Air Gas Insulated Switchgears. The switching equipments are housed in a strong system made of stainless steel which contains climate-friendly, moisture-free and fireproof dry air gas and offers good insulation.
Environmental Impact:
SF6: SF6 gas has high environmental effects due to its high greenhouse effect and global warming potential (GWP).
Dry Air Gas: Dry air gas is a more climate-friendly option compared to SF6 gas. Dry air gas has a low global warming potential and does not contribute to greenhouse gas emissions.
Maintenance and Operation:
Dry air insulation generally requires less maintenance and special handling than SF6 gas. In dry air gas insulated switching, maintenance requirements are simpler and operating costs are lower. Switching equipments are contained in a sealed pressure system that is designed for 30-40 years of lifetime.
Safety:
SF6: SF6 gas is a non-toxic, fireproof and non-explosive gas under normal conditions. However, in a high-energy arc fault, SF6 gas can degenerate and create dangerous by products.
