Gas-Insulated Switchgear (GIS) — Eco-Gas / SF6-Free

up to 38 kV class · vacuum + eco-gas

Overview

Compact gas-insulated switchgear (GIS) using vacuum interrupters and an eco-friendly (SF6-free) insulating gas at near-zero gauge pressure — for space- constrained 15 / 27 / 38 kV class medium-voltage distribution, 60 Hz, with built-in online monitoring and SCADA. Designed to IEEE C37.20.9; UL / CSA certifiable.

This gas-insulated switchgear (GIS) extinguishes the arc with vacuum interrupters and insulates with an eco-friendly, SF6-free gas held at near-zero gauge pressure — combining the compact footprint of gas insulation with a low-global-warming medium. It serves space-constrained 15 / 27 / 38 kV class medium-voltage distribution at 60 Hz, sealed against moisture, dust and salt for urban, coastal and indoor sites.

Built-in gas, arc and condition monitoring with SCADA / IEC 61850 integration let operators manage the network remotely, and an arc-resistant rating per IEEE C37.20.7 is available. Designed and built to IEEE C37.20.9 (gas-insulated switchgear, 1–52 kV), with UL / CSA certification available on request — a smart, reliable choice for data centers, transit and mission-critical facilities.

FAQ

Common questions

Is this switchgear SF6-free?
Yes. It interrupts with vacuum bottles and insulates with an eco-friendly, SF6-free gas at near-zero gauge pressure — avoiding the high global-warming-potential of SF6 while keeping the compact footprint of gas-insulated switchgear.
Which North-American standard governs GIS?
IEEE C37.20.9-2019 covers metal-enclosed switchgear rated 1 kV to 52 kV incorporating gas-insulating systems — the NA adoption for GIS. This unit is designed to it; UL / CSA certification is available on request.
Why choose GIS over air-insulated switchgear?
GIS is much more compact and is sealed against moisture, dust and salt, so it suits space-constrained urban substations, data centers and coastal or harsh-environment sites, 60 Hz, 15 / 27 / 38 kV class.
